+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License along
+ with this program; if not, write to the Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+The options to install udev in the rootfs instead of /usr,
+and udevadm in /sbin:
+ --prefix=%{_prefix} \
+ --with-rootprefix= \
+ --sysconfdir=%{_sysconfdir} \
+ --bindir=/sbin \
+ --libdir=%{_libdir} \
+ --with-rootlibdir=/lib64 \
+ --libexecdir=/lib \
+ --with-systemdsystemunitdir=/lib/systemd/system \
+ --with-selinux
+
+Some tools expect udevadm in 'sbin'. A symlink to udevadm in 'bin'
+needs to be manually created if needed.
+
+The defined location for scripts and binaries which are called
+from rules is (/usr)/lib/udev/ on all systems and architectures. Any
+other location will break other packages, who rightfully expect
+the (/usr)/lib/udev/ directory, to install their rule helper and udev
+rule files.
+
+Default udev rules and persistent device naming rules may be required
+by other software that depends on the data udev collects from the
+devices.

+udev 182
+========
+Rules files in /etc/udev/rules.s/ with the same name as rules files in
+/run/udev/rules.d/ now always have precedence. The stack of files is now:
+/usr/lib (package), /run (runtime, auto-generated), /etc (admin), while
+the later ones override the earlier ones. In other words: the admin has
+always the last say.
+
+USB auto-suspend is now enabled by default for some built-in USB HID
+devices.
+
+/dev/disk/by-path/ links are no longer created for ATA devices behind
+an 'ATA transport class', the logic to extract predictable numbers does
+not exist in the kernel at this moment.
+
+/dev/disk/by-id/scsi-* compatibility links are no longer created for
+ATA devices, they have their own ata-* prefix.
+
+The s390 rule to set mode == 0666 for /dev/z90crypt is is removed from
+the udev tree and will be part of s390utils (or alternatively could be
+done by the kernel driver itself).
+
+The udev-acl tool is no longer provided, it will be part of a future
+ConsoleKit release. On systemd systems, advanced ConsoleKit and udev-acl
+functionality are provided by systemd.
+
+udev 181
+========
+Require kmod version 5.
+
+Provide /dev/cdrom symlink for /dev/sr0.
+
+udev 180
+========
+Fix for ID_PART_ENTRY_* property names, added by the blkid built-in. The
+fix is needed for udisk2 to operate properly.
+
+Fix for skipped rule execution when the kernel has removed the device
+node in /dev again, before the event was even started. The fix is needed
+to run device-mapper/LVM events properly.
+
+Fix for the man page installation, which was skipped when xsltproc was not
+installed.
+
+udev 179
+========
+Bugfix for $name resolution, which broke at least some keymap handling.
+
+udev 178
+========
+Bugfix for the firmware loading behavior with kernel modules which
+try to load firmware in the module_init() path. The blocked event
+runs into a timout now, which should allow the firmware to be loaded.
+
+Bugfix for a wrong DEVNAME= export, which breaks at least the udev-acl
+tool.
+
+Bugfix for missing ID_ properties for GPT partitions.
+
+The RUN+="socket:.." option is deprecated and should not be used. A warning
+during rules parsing is printed now. Services which listen to udev events,
+need to subscribe to the netlink messages with libudev and not let udev block
+in the rules execution until the message is delivered.
+
+udev 177
+========
+Bugfix for rule_generator instalation.
+
+udev 176
+========
+The 'devtmpfs' filesystem is required now, udev will not create or delete
+device nodes anymore, it only adjusts permissions and ownership of device
+nodes and maintains additional symlinks.
+
+A writable /run directory (ususally tmpfs) is required now for a fully
+functional udev, there is no longer a fallback to /dev/.udev.
+
+The default 'configure' install locations have changed. Packages for systems
+with the historic / vs. /usr split need to be adapted, otherwise udev will
+be installed in /usr and not work properly. Example configuration options
+to install things the traditional way are in INSTALL.
+
+The default install location of the 'udevadm' tool moved from 'sbin'
+to /usr/bin. Some tools expect udevadm in 'sbin', a symlink to udevadm
+needs to be manually created if needed, or --bindir=/sbin be specified.
+
+The expected value of '--libexecdir=' has changed and must no longer contain
+the 'udev' directory.
+
+Kernel modules are now loaded directly by linking udev to 'libkmod'. The
+'modprobe' tool is no longer executed by udev.
+
+The 'blkid' tool is no longer executed from udev rules. Udev links
+directly to libblkid now.
+
+Firmware is loaded natively by udev now, the external 'firmware' binary
+is no longer used.
+
+All built-in tools can be listed and tested with 'udevadm test-builtin'.
+
+The 'udevadm control --reload-rules' option has been renamed to '--reload'.
+It now also reloads the kernel module configuration.
+
+The systemd socket files use PassCredentials=yes, which is available in
+systemd version 38.
+
+The udev build system only creates a .xz tarball now.
+
+All tabs in the source code used for indentation are replaced by spaces now. :)
+
+udev 175
+========
+Bugfixes.
+
+udev 174
+========
+Bugfixes.
+
+The udev daemon moved to /lib/udev/udevd. Non-systemd init systems
+and non-dracut initramfs image generators need to change the init
+scripts. Alternatively the udev build needs to move udevd back to
+/sbin or create a symlink in /sbin, which is not done by default.
+
+The path_id, usb_id, input_id tools are built-in commands now and
+the stand-alone tools do not exist anymore. Static lists of file in
+initramfs generators need to be updated. For testing, the commands
+can still be executed standalone with 'udevadm test-builtin <cmd>'.
+
+The fusectl filesystem is no longer mounted directly from udev.
+Systemd systems will take care of mounting fusectl and configfs
+now. Non-systemd systems need to ship their own rule if they
+need these filesystems auto-mounted.
+
+The long deprecated keys: SYSFS=, ID=, BUS= have been removed.
+
+The support for 'udevadm trigger --type=failed, and the
+RUN{fail_event_on_error} attribute was removed.
+
+The udev control socket is now created in /run/udev/control
+and no longer as an abstract namespace one.
+
+The rules to create persistent network interface and cdrom link
+rules automatically in /etc/udev/rules.d/ have been disabled by
+default. Explicit configuration will be required for these use
+cases, udev will no longer try to write any persistent system
+configuration from a device hotplug path.
+
+udev 173
+========
+Bugfixes.
+
+The udev-acl extra is no longer enabled by default now. To enable it,
+--enable-udev_acl needs to be given at ./configure time. On systemd
+systems, the udev-acl rules prevent it from running as the functionality
+has moved to systemd.
+
+udev 172
+========
+Bugfixes.
+
+Udev now enables kernel media-presence polling if available. Part
+of udisks optical drive tray-handling moved to cdrom_id: The tray
+is locked as soon as a media is detected to enable the receiving
+of media-eject-request events. Media-eject-request events will
+eject the media.
+
+Libudev enumerate is now able to enumerate a subtree of a given
+device.
+
+The mobile-action-modeswitch modeswitch tool was deleted. The
+functionality is provided by usb_modeswitch now.
+
+udev 171
+========
+Bugfixes.
+
+The systemd service files require systemd version 28. The systemd
+socket activation make it possible now to start 'udevd' and 'udevadm
+trigger' in parallel.
+
+udev 170
+========
+Fix bug in control message handling, which can lead to a failing
+udevadm control --exit. Thanks to Jürg Billeter for help tracking
+it down.
+
+udev 169
+========
+Bugfixes.
+
+We require at least Linux kernel 2.6.32 now. Some platforms might
+require a later kernel that supports accept4() and similar, or
+need to backport the trivial syscall wiring to the older kernels.
+
+The hid2hci tool moved to the bluez package and was removed.
+
+Many of the extras can be --enable/--disabled at ./configure
+time. The --disable-extras option was removed. Some extras have
+been disabled by default. The current options and their defaults
+can be checked with './configure --help'.
+
+udev 168
+========
+Bugfixes.
+
+Udev logs a warning now if /run is not writable at udevd
+startup. It will still fall back to /dev/.udev, but this is
+now considered a bug.
+
+The running udev daemon can now cleanly shut down with:
+ udevadm control --exit
+
+Udev in initramfs should clean the state of the udev database
+with: udevadm info --cleanup-db which will remove all state left
+behind from events/rules in initramfs. If initramfs uses
+--cleanup-db and device-mapper/LVM, the rules in initramfs need
+to add OPTIONS+="db_persist" for all dm devices. This will
+prevent removal of the udev database for these devices.
+
+Spawned programs by PROGRAM/IMPORT/RUN now have a hard timeout of
+120 seconds per process. If that timeout is reached the spawned
+process will be killed. The event timeout can be overwritten with
+udev rules.
+
+If systemd is used, udev gets now activated by netlink data.
+Systemd will bind the netlink socket which will buffer all data.
+If needed, such setup allows a seemless update of the udev daemon,
+where no event can be lost during a udevd update/restart.
+Packages need to make sure to: systemctl stop udev.socket udev.service
+or 'mask' udev.service during the upgrade to prevent any unwanted
+auto-spawning of udevd.
+This version of udev conflicts with systemd version below 25. The
+unchanged service files will not wirk correctly.
+
+udev 167
+========
+Bugfixes.
+
+The udev runtime data moved from /dev/.udev/ to /run/udev/. The
+/run mountpoint is supposed to be a tmpfs mounted during early boot,
+available and writable to for all tools at any time during bootup,
+it replaces /var/run/, which should become a symlink some day.
+
+If /run does not exist, or is not writable, udev will fall back using
+/dev/.udev/.
+
+On systemd systems with initramfs and LVM used, packagers must
+make sure, that the systemd and initramfs versions match. The initramfs
+needs to create the /run mountpoint for udev to store the data, and
+mount this tmpfs to /run in the rootfs, so the that the udev database
+is preserved for the udev version started in the rootfs.
+
+The command 'udevadm info --convert-db' is gone. The udev daemon
+itself, at startup, converts any old database version if necessary.
+
+The systemd services files have been reorganized. The udev control
+socket is bound by systemd and passed to the started udev daemon.
+The udev-settle.service is no longer active by default. Services which
+can not handle hotplug setups properly need to actively pull it in, to
+act like a barrier. Alternatively the settle service can be unconditionally
+'systemctl'enabled, and act like a barrier for basic.target.
+
+The fstab_import callout is no longer built or installed. Udev
+should not be used to mount, does not watch changes to fstab, and
+should not mirror fstab values in the udev database.
+
+udev 166
+========
+Bugfixes.
+
+New and updated keymaps.
+
+udev 165
+========
+Bugfixes.
+
+The udev database has changed, After installation of a new udev
+version, 'udevadm info --convert-db' should be called, to let the new
+udev/libudev version read the already stored data.
+
+udevadm now supports quoting of property values, and prefixing of
+key names:
+ $ udevadm info --export --export-prefix=MY_ --query=property -n sda
+ MY_MAJOR='259'
+ MY_MINOR='0'
+ MY_DEVNAME='/dev/sda'
+ MY_DEVTYPE='disk'
+ ...
+
+libudev now supports:
+ udev_device_get_is_initialized()
+ udev_enumerate_add_match_is_initialized()
+to be able to skip devices the kernel has created , but udev has
+not already handled.
+
+libudev now supports:
+ udev_device_get_usec_since_initialized()
+to retrieve the "age" of a udev device record.
+
+GUdev supports a more generic GUdevEnumerator class, udev TAG
+handling, device initialization and timestamp now.
+
+The counterpart of /sys/dev/{char,block}/$major:$minor,
+/dev/{char,block}/$major:$minor symlinks are now unconditionally
+created, even when no rule files exist.
+
+New and updated keymaps.
+
+udev 164
+========
+Bugfixes.
+
+GUdev moved from /usr to /.
+
+udev 163
+========
+Bugfixes.
+
+udev 162
+========
+Bugfixes.
+
+Persistent network naming rules are disabled inside of Qemu/KVM now.
+
+New and updated keymaps.
+
+Udev gets unconditionally enabled on systemd installations now. There
+is no longer the need to to run 'systemctl enable udev.service'.
+
+udev 161
+========
+Bugfixes.
+
+udev 160
+========
+Bugfixes.
+
+udev 159
+========
+Bugfixes.
+
+New and fixed keymaps.
+
+Install systemd service files if applicable.
+
+udev 158
+========
+Bugfixes.
+
+All distribution specific rules are removed from the udev source tree,
+most of them are no longer needed. The Gentoo rules which allow to support
+older kernel versions, which are not covered by the default rules anymore
+has moved to rules/misc/30-kernel-compat.rules.
+
+udev 157
+========
+Bugfixes.
+
+The option --debug-trace and the environemnt variable UDEVD_MAX_CHILDS=
+was removed from udevd.
+
+Udevd now checks the kernel commandline for the following variables:
+ udev.log-priority=<syslog priority>
+ udev.children-max=<maximum number of workers>
+ udev.exec-delay=<seconds to delay the execution of RUN=>
+to help debuging coldplug setups where the loading of a kernel
+module crashes the system.
+
+The subdirectory in the source tree rules/packages has been renamed to
+rules/arch, anc contains only architecture specific rules now.

+udev 156

+Bugfixes.
+
+udev 155
+========
+Bugfixes.
+
+Now the udev daemon itself, does on startup:
+ - copy the content of /lib/udev/devices to /dev
+ - create the standard symlinks like /dev/std{in,out,err},
+ /dev/core, /dev/fd, ...
+ - use static node information provided by kernel modules
+ and creates these nodes to allow module on-demand loading
+ - possibly apply permissions to all ststic nodes from udev
+ rules which are annotated to match a static node
+
+The default mode for a device node is 0600 now to match the kernel
+created devtmpfs defaults. If GROUP= is specified and no MODE= is
+given the default will be 0660.
+
+udev 154
+========
+Bugfixes.
+
+Udev now gradually starts to pass control over the primary device nodes
+and their names to the kernel, and will in the end only manage the
+permissions of the node, and possibly create additional symlinks.
+As a first step NAME="" will be ignored, and NAME= setings with names
+other than the kernel provided name will result in a logged warning.
+Kernels that don't provide device names, or devtmpfs is not used, will
+still work as they did before, but it is strongly recommended to use
+only the same names for the primary device node as the recent kernel
+provides for all devices.
+
+udev 153
+========
+Fix broken firmware loader search path.
+
+udev 152
+========
+Bugfixes.
+
+"udevadm trigger" defaults to "change" events now instead of "add"
+events. The "udev boot script" might need to add "--action=add" to
+the trigger command if not already there, in case the initial coldplug
+events are expected as "add" events.
+
+The option "all_partitons" was removed from udev. This should not be
+needed for usual hardware. Udev can not safely make assumptions
+about non-existing partition major/minor numbers, and therefore no
+longer provide this unreliable and unsafe option.
+
+The option "ignore_remove" was removed from udev. With devtmpfs
+udev passed control over device nodes to the kernel. This option
+should not be needed, or can not work as advertised. Neither
+udev nor the kernel will remove device nodes which are copied from
+the /lib/udev/devices/ directory.
+
+All "add|change" matches are replaced by "!remove" in the rules and
+in the udev logic. All types of events will update possible symlinks
+and permissions, only "remove" is handled special now.
+
+The modem modeswitch extra was removed and the external usb_modeswitch
+program should be used instead.
+
+New and fixed keymaps.
+
+udev 151
+========
+Bugfixes.
+
+udev 150
+========
+Bugfixes.
+
+Kernels with SYSFS_DEPRECATED=y are not supported since a while. Many users
+depend on the current sysfs layout and the information not available in the
+deprecated layout. All remaining support for the deprecated sysfs layout is
+removed now.
+
+udev 149
+========
+Fix for a possible endless loop in the new input_id program.
+
+udev 148
+========
+Bugfixes.
+
+The option "ignore_device" does no longer exist. There is no way to
+ignore an event, as libudev events can not be suppressed by rules.
+It only prevented RUN keys from being executed, which results in an
+inconsistent behavior in current setups.
+
+BUS=, SYSFS{}=, ID= are long deprecated and should be SUBSYSTEM(S)=,
+ATTR(S){}=, KERNEL(S)=. It will cause a warning once for every rule
+file from now on.
+
+The support for the deprecated IDE devices has been removed from the
+default set of rules. Distros who still care about non-libata drivers
+need to add the rules to the compat rules file.
+
+The ID_CLASS property on input devices has been replaced by the more accurate
+set of flags ID_INPUT_{KEYBOARD,KEY,MOUSE,TOUCHPAD,TABLET,JOYSTICK}. These are
+determined by the new "input_id" prober now. Some devices, such as touchpads,
+can have several classes. So if you previously had custom udev rules which e. g.
+checked for ENV{ID_CLASS}=="kbd", you need to replace this with
+ENV{ID_INPUT_KEYBOARD}=="?*".
+
+udev 147
+========
+Bugfixes.
+
+To support DEVPATH strings larger than the maximum file name length, the
+private udev database format has changed. If some software still reads the
+private files in /dev/.udev/, which it shouldn't, now it's time to fix it.
+Please do not port anything to the new format again, everything in /dev/.udev
+is and always was private to udev, and may and will change any time without
+prior notice.
+
+Multiple devices claiming the same names in /dev are limited to symlinks
+only now. Mixing identical symlink names and node names is not supported.
+This reduces the amount of data in the database significantly.
+
+NAME="%k" causes a warning now. It's is and always was completely superfluous.
+It will break kernel supplied DEVNAMEs and therefore it needs to be removed
+from all rules.
+
+Most NAME= instructions got removed. Kernel 2.6.31 supplies the needed names
+if they are not the default. To support older kernels, the NAME= rules need to
+be added to the compat rules file.
+
+Symlinks to udevadm with the old command names are no longer resolved to
+the udevadm commands.
+
+The udev-acl tool got adopted to changes in ConsoleKit. Version 0.4.1 is
+required now.
+
+The option "last_rule" does no longer exist. Its use breaks too many
+things which expect to be run from independent later rules, and is an idication
+that something needs to be fixed properly instead.
+
+The gudev API is no longer marked as experimental,
+G_UDEV_API_IS_SUBJECT_TO_CHANGE is no longer needed. The gudev introspection
+is enabled by default now. Various projects already depend on introspection
+information to bind dynamic languages to the gudev interfaces.
+
+udev 146
+========
+Bugfixes.
+
+The udevadm trigger "--retry-failed" option, which is replaced since quite
+a while by "--type=failed" is removed.
+
+The failed tracking was not working at all for a few releases. The RUN
+option "ignore_error" is replaced by a "fail_event_on_error" option, and the
+default is not to track any failing RUN executions.
+
+New keymaps, new modem, hid2hci updated.
+
+udev 145
+========
+Fix possible crash in udevd when worker processes are busy, rules are
+changed at the same time, and workers get killed to reload the rules.
+
+udev 144
+========
+Bugfixes.
+
+Properties set with ENV{.FOO}="bar" are marked private by starting the
+name with a '.'. They will not be stored in the database, and not be
+exported with the event.
+
+Firmware files are looked up in:
+ /lib/firmware/updates/$(uname -r)
+ /lib/firmware/updates
+ /lib/firmware/$(uname -r)
+ /lib/firmware"
+now.
+
+ATA devices switched the property from ID_BUS=scsi to ID_BUS=ata.
+ata_id, instead of scsi_id, is the default tool now for ATA devices.
+
+udev 143
+========
+Bugfixes.
+
+The configure options have changed because another library needs to be
+installed in a different location. Instead of exec_prefix and udev_prefix,
+libdir, rootlibdir and libexecdir are used. The Details are explained in
+the README file.
+
+Event processes now get re-used after they handled an event. This reduces
+the number of forks and the pressure on the CPU significantly, because
+cloned event processes no longer cause page faults in the main daemon.
+After the events have settled, a few worker processes stay around for
+future events, all others get cleaned up.
+
+To be able to use signalfd(), udev depends on kernel version 2.6.25 now.
+Also inotify support is mandatory now to run udev.
+
+The format of the queue exported by the udev damon has changed. There is
+no longer a /dev/.udev/queue/ directory. The current event queue can be
+accessed with udevadm settle and libudedv.
+
+Libudev does not have the unstable API header anymore. From now on,
+incompatible changes will be handled by bumping the library major version.
+
+To build udev from the git tree gtk-doc is needed now. The tarballs will
+build without it and contain the pre-built documentation. An online copy
+is available here:
+ http://www.kernel.org/pub/linux/utils/kernel/hotplug/libudev/
+
+The tools from the udev-extras repository have been merged into the main
+udev repository. Some of the extras have larger external dependencies, and
+they can be disabled with the configure switch --disable-extras.
+
+udev 142
+========
+Bugfixes.
+
+The program vol_id and the library libvolume_id are removed from the
+repository. Libvolume_id is merged with libblkid from the util-linux-ng
+package. Persistent disk links for label and uuid depend on the
+util-linux-ng version (2.15) of blkid now. Older versions of blkid
+can not be used with udev.
+
+Libudev allows to subscribe to udev events. To prevent unwanted messages
+to be delivered, and waking up the subscribing process, a filter can be
+installed, to drop messages inside a kernel socket filter. The filters
+match on the <subsytem>:<devtype> properties of the device.
+ This is part of the ongoing effort to replace HAL, and switch current
+users over to directly use libudev.
+ Libudev is still marked as experimental, and its interface might
+eventually change if needed, but no major changes of the currently exported
+interface are expected anymore, and a first stable release should happen
+soon.
+
+A too old kernel (2.6.21) or a kernel with CONFIG_SYSFS_DEPRECATED
+is not supported since while and udevd will log an error message at
+startup. It should still be able to boot-up, but advanced rules and system
+services which depend on the information not available in the old sysfs
+format will fail to work correctly.
+
+DVB device naming is supplied by the kernel now. In case older kernels
+need to be supported, the old shell script should be added to a compat
+rules file.
+
+udev 141
+========
+Bugfixes.
+
+The processed udev events get send back to the netlink socket. Libudev
+provides access to these events. This is work-in-progress, to replace
+the DeviceKit daemon functionality directly with libudev. There are
+upcoming kernel changes to allow non-root users to subcribe to these
+events.
+
+udev 140
+========
+Bugfixes.
+
+"udevadm settle" now optionally accepts a range of events to wait for,
+instead of waiting for "all" events.
+
+udev 139
+========
+Bugfixes.
+
+The installed watch for block device metadata changes is now removed
+during event hadling, because some (broken) tools may be called from udev
+rules and (wrongly) open the device with write access. After the finished
+event handling the watch is restored.
+
+udev 138
+========
+Bugfixes.
+
+Device nodes can be watched for changes with inotify with OPTIONS="watch".
+If closed after being opened for writing, a "change" uevent will occur.
+/dev/disk/by-{label,uuid}/* symlinks will be automatically updated.
+
+udev 137
+========
+Bugfixes.
+
+The udevadm test command has no longer a --force option, nodes and symlinks
+are always updated with a test run now.
+
+The udevd daemon can be started with --resolve-names=never to avoid all user
+and group lookups (e.g. in cut-down systems) or --resolve-names=late to
+lookup user and groups every time events are handled.
+
+udev 136
+========
+Bugfixes.
+
+We are currently merging the Ubuntu rules in the udev default rules,
+and get one step closer to provide a common Linux /dev setup, regarding
+device names, symlinks, and default device permissions. On udev startup,
+we now expect the following groups to be resolvable to their ids with
+glibc's getgrnam():
+ disk, cdrom, floppy, tape, audio, video, lp, tty, dialout, kmem.
+LDAP setups need to make sure, that these groups are always resolvable at
+bootup, with only the rootfs mounted, and without network access available.
+
+Some systems may need to add some new, currently not used groups, or need
+to add some users to new groups, but the cost of this change is minimal,
+compared to the pain the current, rather random, differences between the
+various distributions cause for upstream projects and third-party vendors.
+
+In general, "normal" users who log into a machine should never be a member
+of any such group, but the device-access should be managed by dynamic ACLs,
+which get added and removed for the specific users on login/logout and
+session activity/inactivity. These groups are only provided for custom setups,
+and mainly system services, to allow proper privilege separation.
+A video-streaming daemon uid would be a member of "audio" and "video", to get
+access to the sound and video devices, but no "normal" user should ever belong
+to the "audio" group, because he could listen to the built-in microphone with
+any ssh-session established from the other side of the world.
+
+/dev/serial/by-{id,path}/ now contains links for ttyUSB devices,
+which do not depend on the kernel device name. As usual, unique
+devices - only a single one per product connected, or a real
+USB serial number in the device - are always found with the same
+name in the by-id/ directory.
+Completely identical devices may overwrite their names in by-id/
+and can only be found reliably in the by-path/ directory. Devices
+specified by by-path/ must not change their connection, like the
+USB port number they are plugged in, to keep their name.
+
+To support some advanced features, Linux 2.6.22 is the oldest supported
+version now. The kernel config with enabled SYSFS_DEPRECATED is no longer
+supported. Older kernels should still work, and devices nodes should be
+reliably created, but some rules and libudev will not work correctly because
+the old kernels do not provide the expected information or interfaces.
+
+udev 135
+========
+Bugfixes.
+
+Fix for a possible segfault while swapping network interface names in udev
+versions 131-134.
+
+udev 134
+========
+Bugfixes.
+
+The group "video" is part of the default rules now.
+
+udev 133
+========
+Bugfix for kernels using SYSFS_DEPRECATED* option and finding parent
+block devices in some cases. No common distro uses this option anymore,
+and we do not get enough testing for this and recent udev versions. If
+this option is not needed to run some old distro with a new kernel,
+it should be disabled in the kernel config.
+
+Bugfix for the $links substitution variable, which may crash if no links
+are created. This should not happen in usual setups because we always
+create /dev/{block,char}/ links.
+
+The strings of the parsed rules, which are kept in memory, no longer
+contain duplicate entries, or duplicate tails of strings. This, and the
+new rules parsing/matching code reduces the total in-memory size of
+a huge distro rule sets to 0.08 MB, compared to the 1.2MB of udev
+version 130.
+
+The export of DEVTYPE=disk/partition got removed from the default
+rules. This value is available from the kernel. The pnp shell script
+modprobe hack is removed from the default rules. ACPI devices have _proper_
+modalias support and take care of the same functionality.
+Installations which support old kernels, but install current default
+udev rules may want to add that to the compat rules file.
+
+Libvolume_id now always probes for all known filesystems, and does not
+stop at the first match. Some filesystems are marked as "exclusive probe",
+and if any other filesytem type matches at the same time, libvolume_id
+will, by default, not return any probing result. This is intended to prevent
+mis-detection with conflicting left-over signatures found from earlier
+file system formats. That way, we no longer depend on the probe-order
+in case of multiple competing signatures. In some setups the kernel allows
+to mount a volume with just the old filesystem signature still in place.
+This may damage the new filesystem and cause data-loss, just by mounting
+it. Because volume_id can not decide which one the correct signature is,
+the wrong signatures need to be removed manually from the volume, or the
+volume needs to be reformatted, to enable filesystem detection and possible
+auto-mounting.
+
+udev 132
+========
+Fix segfault if compiled without optimization and dbg() does not get
+compiled out and uses variables which are not available.
+
+udev 131
+========
+Bugfixes. (And maybe new bugs. :))
+
+The rule matching engine got converted from a rule list to a token
+array which reduced the in-memory rules representation of a full
+featured distros with thousends of udev rules from 1.2MB to 0.12 MB.
+Limits like 5 ENV and ATTR matches, and one single instance for most
+other keys per rule are gone.
+
+The NAME assignment is no longer special cased. If later rules assign
+a NAME value again, the former value will be overwritten. As usual
+for most other keys, the NAME value can be protected by doing a final
+assignment with NAME:="<value>".
+
+All udev code now uses libudev, which is also exported. The library
+is still under development, marked as experimental, and its interface
+may change as long as the DeviceKit integration is not finished.
+
+Many thanks to Alan Jenkins for his continuous help, and finding and
+optimizing some of the computing expensive parts.
+
+udev 130
+========
+Bugfixes.
+
+Kernel devices and device nodes are connected now by reverse indizes in
+/sys and /dev. A device number retrieved by a stat() or similar, the
+kernel device directory can be found by looking up:
+ /sys/dev/{block,char}/<maj>:<min>
+and the device node of the same device by looking up:
+ /dev/{block,char}/<maj>:<min>
+
+udev 129
+========
+Fix recently introduced bug, which caused a compilation without large
+file support, where vol_id does not recognize raid signatures at the end
+of a volume.
+
+Firewire disks now create both, by-id/scsi-* and by-id/ieee-* links.
+Seems some kernel versions prevent the creation of the ieee-* links,
+so people used the scsi-* link which disappeared now.
+
+More libudev work. Almost all udevadm functionality comes from libudev
+now.
+
+udevadm trigger has a new option --type, which allows to trigger events
+for "devices", for "subsystems", or "failed" devices. The old option
+--retry-failed" still works, but is no longer mentioned in the man page.
+
+udev 128
+========
+Bugfixes.
+
+The udevadm info --device-id-of-file= output has changed to use
+the obvious format. Possible current users should use the --export
+option which is not affected.
+
+The old udev commands symlinks to udevadm are not installed, if
+these symlinks are used, a warning is printed.
+
+udev 127
+========
+Bugfixes.
+
+Optical drive's media is no longer probed for raid signatures,
+reading the end of the device causes some devices to malfunction.
+Also the offset of the last session found is used now to probe
+for the filesystem.
+
+The volume_id library got a major version number update to 1,
+some deprecated functions are removed.
+
+A shared library "libudev" gets installed now to provide access
+to udev device information. DeviceKit, the successor of HAL, will
+need this library to access the udev database and search sysfs for
+devices.
+The library is currently in an experimental state, also the API is
+expected to change, as long as the DeviceKit integration is not
+finished.
+
+udev 126
+========
+We use ./configure now. See INSTALL for details. Current
+options are:
+ --prefix=
+ "/usr" - prefix for man pages, include files
+ --exec-prefix=
+ "" - the root filesystem, prefix for libs and binaries
+ --sysconfdir=
+ "/etc"
+ --with-libdir-name=
+ "lib" - directory name for libraries, not a path name
+ multilib 64bit systems may use "lib64" instead of "lib"
+ --enable-debug
+ compile-in verbose debug messages
+ --disable-logging
+ disable all logging and compile-out all log strings
+ --with-selinux
+ link against SELInux libraries, to set the expected context
+ for created files
+
+In the default rules, the group "disk" gets permissions 0660 instead
+of 0640. One small step closer to unify distro rules. Some day, all
+distros hopefully end up with the same set of rules.
+
+No symlinks to udevadm are installed anymore, if they are still needed,
+they should be provided by the package.
+
+udev 125
+========
+Bugfixes.
+
+Default udev rules, which are not supposed to be edited by the user, should
+be placed in /lib/udev/rules.d/ now, to make it clear that they are private to
+the udev package and will be replaced with an update. Udev will pick up rule
+files from:
+ /lib/udev/rules.d/ - default installed rules
+ /etc/udev/rules.d/ - user rules + on-the-fly generated rules
+ /dev/.udev/rules.d/ - temporary non-persistent rules created after bootup
+It does not matter in which directory a rule file lives, all files are sorted
+in lexical order.
+
+To help creating /dev/root, we have now:
+ $ udevadm info --export --export-prefix="ROOT_" --device-id-of-file=/
+ ROOT_MAJOR=8
+ ROOT_MINOR=5
+In case the current --device-id-of-file is already used, please switch to
+the --export format version, it saves the output parsing and the old
+format will be changed to use ':' as a separator, like the format in the
+sysfs 'dev' file.
+
+udev 124
+========
+Fix cdrom_id to properly recognize blank media.
+
+udev 123
+========
+Bugfixes.
+
+Tape drive id-data is queried from /dev/bsg/* instead of the tape
+nodes. This avoids rewinding tapes on open().
+
+udev 122
+========
+Bugfixes.
+
+The symlinks udevcontrol and udevtrigger are no longer installed by
+the Makefile.
+
+The scsi_id program does not depend on sysfs anymore. It can speak
+SGv4 now, so /dev/bsg/* device nodes can be used, to query SCSI device
+data, which should solve some old problems with tape devices, where
+we better do not open all tape device nodes to identify the device.
+
+udev 121
+========
+Many bugfixes.
+
+The cdrom_id program is replaced by an advanced version, which can
+detect most common device types, and also properties of the inserted
+media. This is part of moving some basic functionality from HAL into
+udev (and the kernel).
+
+udev 120
+========
+Bugfixes.
+
+The last WAIT_FOR_SYSFS rule is removed from the default rules.
+
+The symlinks to udevadm for the debugging tools: udevmonitor and
+udevtest are no longer created.
+
+The symlinks to the udevadm man page for the old tool names are
+no longer created.
+
+Abstract namespace sockets paths in RUN+="socket:@<path>" rules,
+should be prefixed with '@' to indicate that the path is not a
+real file.

+
+udev 117
+========
+Bugfixes.
+
+All udev tools are merged into a single binary called udevadm.
+The old names of the tools are built-in commands in udevadm now.
+Symlinks to udevadm, with the names of the old tools, provide
+the same functionality as the standalone tools. There is also
+only a single udevadm.8 man page left for all tools.
+
+Tools like mkinitramfs should be checked, if they need to include
+udevadm in the list of files.
+
+udev 116
+========
+Bugfixes.
+
+udev 115
+========
+Bugfixes.
+
+The etc/udev/rules.d/ directory now contains a default set of basic
+udev rules. This initial version is the result of a rules file merge
+of Fedora and openSUSE. For these both distros only a few specific
+rules are left in their own file, named after the distro. Rules which
+are optionally installed, because they are only valid for a specific
+architecture, or rules for subsystems which are not always used are
+in etc/udev/packages/.
+
+udev 114
+========
+Bugfixes.
+
+Dynamic rules can be created in /dev/.udev/rules.d/ to trigger
+actions by dynamically created rules.
+
+SYMLINK=="<value>" matches agains the entries in the list of
+currently defined symlinks. The links are not created in the
+filesystem at that point in time, but the values can be matched.
+
+RUN{ignore_error}+="<program>" will ignore any exit code from the
+program and not record as a failed event.
+
+udev 113
+========
+Bugfixes.
+
+Final merge of patches/features from the Ubuntu package.
+
+udev 112
+========
+Bugfixes.
+
+Control characters in filesystem label strings are no longer silenty
+removed, but hex-encoded, to be able to uniquely identify the device
+by its symlink in /dev/disk/by-label/.
+If libvolume_id is used by mount(8), LABEL= will work as expected,
+if slashes or other characters are used in the label string.
+
+To test the existence of a file, TEST=="<file>" and TEST!="<file>"
+can be specified now. The TEST key accepts an optional mode mask
+TEST{0100}=="<is executable file>".
+
+Scsi_id now supports a mode without expecting scsi-specific sysfs
+entries to allow the extraction of cciss-device persistent properties.
+
+udev 111
+========
+Bugfixes.
+
+In the future, we may see uuid's which are just simple character
+strings (see the DDF Raid Specification). For that reason vol_id now
+exports ID_FS_UUID_SAFE, just like ID_FS_LABEL_SAFE. For things like
+the creation of symlinks, the *_SAFE values ensure, that no control
+or whitespace characters are used in the filename.
+
+Possible users of libvolume_id, please use the volume_id_get_* functions.
+The public struct will go away in a future release of the library.

+The directory multiplexer for dev.d/ and hotplug.d are finally removed
+from the udev package.
+
+udev 107
+========
+Bugfixes.
+
+Symlinks can have priorities now, the priority is assigned to the device
+and specified with OPTIONS="link_priority=100". Devices with higher
+priorities overwrite the symlinks of devices with lower priorities.
+If the device that currently owns the link, goes away, the symlink
+will be removed, and recreated, pointing to the next device with the
+highest actual priority. This should make /dev/disk/by-{label,uuid,id}
+more reliable, if multiple devices contain the same metadata and overwrite
+these symlinks.
+
+The dasd_id program is removed from the udev tree, and dasdinfo, with the
+needed rules, are part of the s390-tools now.
+
+Please add KERNEL=="[0-9]*:[0-9]*" to the scsi wait-for-sysfs rule,
+we may get the scsi sysfs mess fixed some day, and this will only catch
+the devices we are looking for.
+
+USB serial numbers for storage devices have the target:lun now appended,
+to make it possibble to distinguish broken multi-lun devices with all
+the same SCSI identifiers.
+
+Note: The extra "run_directory" which searches and executes stuff in
+/etc/hotplug.d/ and /etc/dev.d/ is long deprecated, and will be removed
+with the next release. Make sure, that you don't use it anymore, or
+provides your own implementation of that inefficient stuff.
+We are tired of reports about a "slow udev", because these directories
+contain stuff, that runs with _every_ event, instead of using rules,
+that run programs only for the matching events.
+
+udev 106
+========
+Bugfixes.
+
+udev 105
+========
+Bugfixes.
+
+DRIVER== will match only for devices that actually have a real
+driver. DRIVERS== must be used, if parent devices should be
+included in the match.
+
+Libvolume_id's "linux_raid" detection needed another fix.
+
+udev 104
+========
+Bugfixes.
+
+udev 103
+========
+Add additional check to volume_id detection of via_raid, cause
+some company decided to put a matching pattern all over the empty
+storage area of their music players.
+
+udev 102
+========
+Fix path_id for SAS devices.
+
+udev 101
+========
+The udev daemon can be started with --debug-trace now, which will
+execute all events serialized to get a chance to catch a possible
+action that crashes the box.
+
+A warning is logged, if PHYSDEV* keys, the "device" link, or a parent
+device attribute like $attr{../file} is used, only WAIT_FOR_SYSFS rules
+are excluded from the warning. Referencing parent attributes directly
+may break when something in the kernel driver model changes. Udev will
+just find the attribute by walking up the parent chain.
+
+Udevtrigger now sorts the list of devices depending on the device
+dependency, so a "usb" device is triggered after the parent "pci"
+device.
+
+udev 100
+========
+Revert persistent-storage ata-serial '_' '-' replacement.
+
+udev 099
+========
+Bugfixes.
+
+Udevtrigger can now filter the list of devices to be triggered. Matches
+for subsystems or sysfs attributes can be specified.
+
+The entries in /dev/.udev/queue and /dev/.udev/failed have changed to
+zero-sized files to avoid pointing to /sys and confuse broken tools which
+scan the /dev directory. To retry failed events, udevtrigger --retry-failed
+should be used now.
+
+The rules and scripts to create udev rules for persistent network
+devices and optical drives are in the extras/rules_generator directory
+now. If you use something similar, please consider replacing your own
+version with this, to share the support effort. The rule_generator
+installs its own rules into /etc/udev/rules.d.
+
+The cdrom_id tool installs its own rule now in /etc/udev/rules.d, cause
+the rule_generator depends on cdrom_id to be called in an earlier rule.
+
+udev 098
+========
+Bugfixes.
+
+Renaming of some key names (the old names still work):
+BUS -> SUBSYSTEMS, ID -> KERNELS, SYSFS -> ATTRS, DRIVER -> DRIVERS.
+(The behavior of the key DRIVER will change soon in one of the next
+releases, to match only the event device, please switch to DRIVERS
+instead. If DRIVER is used, it will behave like DRIVERS, but an error
+is logged.
+With the new key names, we have a more consistent and simpler scheme.
+We can match the properties of the event device only, with: KERNEL,
+SUBSYSTEM, ATTR, DRIVER. Or include all the parent devices in the match,
+with: KERNELS, SUBSYSTEMS, ATTRS, DRIVERS. ID, BUS, SYSFS, DRIVER are no
+longer mentioned in the man page and should be switched in the rule
+files.
+
+ATTR{file}="value" can be used now, to write to a sysfs file of the
+event device. Instead of:
+ ..., SYSFS{type}=="0|7|14", RUN+="/bin/sh -c 'echo 60 > /sys$$DEVPATH/timeout'"
+we now can do:
+ ..., ATTR{type}=="0|7|14", ATTR{timeout}="60"
+
+All the PHYSDEV* keys are deprecated and will be removed from a
+future kernel:
+ PHYDEVPATH - is the path of a parent device and should not be
+ needed at all.
+ PHYSDEVBUS - is just a SUBSYSTEM value of a parent, and can be
+ matched with SUBSYSTEMS==
+ PHYSDEVDRIVER - for bus devices it is available as ENV{DRIVER}.
+ Newer kernels will have DRIVER in the environment,
+ for older kernels udev puts in. Class device will
+ no longer carry this property of a parent and
+ DRIVERS== can be used to match such a parent value.
+Note that ENV{DRIVER} is only available for a few bus devices, where
+the driver is already bound at device event time. On coldplug, the
+events for a lot devices are already bound to a driver, and they will have
+that value set. But on hotplug, at the time the kernel creates the device,
+it can't know what driver may claim the device after that, therefore
+in most cases it will be empty.
+
+Failed events should now be re-triggered with:
+ udevtrigger --retry-failed.
+Please switch to this command, so we keep the details of the /dev/.udev/failed/
+files private to the udev tools. We may need to switch the current symlink
+target, cause some obviously broken tools try to scan all files in /dev
+including /dev/.udev/, find the links to /sys and end up stat()'ing sysfs files
+million times. This takes ages on slow boxes.
+
+The udevinfo attribute walk (-a) now works with giving a device node
+name (-n) instead of a devpath (-p). The query now always works, also when
+no database file was created by udev.
+
+The built-in /etc/passwd /etc/group parser is removed, we always depend on
+getpwnam() and getgrnam() now. One of the next releases will depend on
+fnmatch() and may use getopt_long().
+
+udev 097
+========
+Bugfixes and small improvements.
+
+udev 096
+========
+Fix path_id for recent kernels.
+
+udev 095
+========
+%e is finally gone.
+
+Added support for swapping network interface names, by temporarily
+renaming the device and wait for the target name to become free.
+
+udev 094
+========
+The built-in MODALIAS key and substitution is removed.
+
+udev 093
+========
+The binary firmware helper is replaced by the usual simple
+shell script. Udevsend is removed from the tree.
+
+udev 092
+========
+Bugfix release.
+
+udev 091
+========
+Some more keys require the correct use of '==' and '=' depending
+on the kind of operation beeing an assignment or a match. Rules
+with invalid operations are skipped and logged to syslog. Please
+test with udevtest if the parsing of your rules throws errors and
+fix possibly broken rules.
+
+udev 090
+========
+Provide "udevsettle" to wait for all current udev events to finish.
+It also watches the current kernel netlink queue by comparing the
+even sequence number to make sure that there are no current pending
+events that have not already arrived in the daemon.
+
+udev 089
+========
+Fix rule to skip persistent rules for removable IDE devices, which
+also skipped optical IDE drives.
+
+All *_id program are installed in /lib/udev/ by default now.
+
+No binary is stripped anymore as this should be done in the
+packaging process and not at build time.
+
+libvolume_id is provided as a shared library now and vol_id is
+linked against it. Also one of the next HAL versions will require
+this library, and the HAL build process will also require the
+header file to be installed. The copy of the same code in HAL will
+be removed to have only a single copy left on the system.
+
+udev 088
+========
+Add persistent links for SCSI tapes. The rules file is renamed
+to 60-persistent-storage.rules.
+
+Create persistent path for usb devices. Can be used for all sorts
+of devices that can't be distinguished by other properties like
+multiple identical keyboards and mice connected to the same box.
+
+Provide "udevtrigger" program to request events on coldplug. The
+shell script is much too slow with thousends of devices.
+
+udev 087
+========
+Fix persistent disk rules to exclude removable IDE drives.
+
+Warn if %e, $modalias or MODALIAS is used.
+
+udev 086
+========
+Fix queue export, which wasn't correct for subsequent add/remove
+events for the same device.
+
+udev 085
+========
+Fix cramfs detection on big endian.
+
+Make WAIT_FOR_SYSFS usable in "normal" rules and silent if the whole
+device goes away.
+
+udev 084
+========
+If BUS== and SYSFS{}== have been used in the same rule, the sysfs
+attributes were only checked at the parent device that matched the
+by BUS requested subsystem. Fix it to also look at the device we
+received the event for.
+
+Build variable CROSS has changed to CROSS_COMPILE to match the kernel
+build name.
+
+udev 083
+========
+Fix a bug where NAME="" would prevent RUN from beeing executed.
+
+RUN="/bin/program" does not longer automatically add the subsystem
+as the first parameter. This is from the days of /sbin/hotplug
+which is dead now and it's just confusing to need to add a space at
+the end of the program name to prevent this.
+If you use rules that need the subsystem as the first parameter,
+like the old "udev_run_hotlugd" and "udev_run_devd", add the subsystem
+to the key like RUN+="/bin/program $env{SUBSYSTEM}".
+
+udev 082
+========
+The udev man page has moved to udev(7) as it does not describe a command
+anymore. The programs udev, udevstart and udevsend are no longer installed
+by default and must be copied manually, if they should be installed or
+included in a package.
+
+Fix a bug where "ignore_device" could run earlier collected RUN keys before
+the ignore rule was applied.
+
+More preparation for future sysfs changes. usb_id and scsi_id no longer
+depend on a magic order of devices in the /devices chain. Specific devices
+should be requested by their subsytem.
+
+This will always find the scsi parent device without depending on a specific
+path position:
+ dev = sysfs_device_get(devpath);
+ dev_usb = sysfs_device_get_parent_with_subsystem(dev, "scsi");
+
+The "device" link in the current sysfs layout will be automatically
+_resolved_ as a parent and in the new sysfs layout it will just _be_ the
+parent in the devpath. If a device is requested by it's symlink, like all
+class devices in the new sysfs layout will look like, it gets automatically
+resolved and substituted with the real devpath and not the symlink path.
+
+Note:
+A similar logic must be applied to _all_ sysfs users, including
+scripts, that search along parent devices in sysfs. The explicit use of
+the "device" link must be avoided. With the future sysfs layout all
+DEVPATH's will start with /devices/ and have a "subsystem" symlink poiting
+back to the "class" or the "bus". The layout of the parent devices in
+/devices is not necessarily expected to be stable across kernel releases and
+searching for parents by their subsystem should make sysfs users tolerant
+for changed parent chains.
+
+udev 081
+========
+Prepare udev to work with the experimental kernel patch, that moves
+/sys/class devices to /sys/devices and /sys/block to /sys/class/block.
+
+Clarify BUS, ID, $id usage and fix $id behavior. This prepares for
+moving the class devices to /sys/devices.
+
+Thanks again to Marco for help finding a hopefully nice compromise
+to make %b simpler and working again.
+
+udev 080
+========
+Complete removal of libsysfs, replaced by simple helper functions
+which are much simpler and a bit faster. The udev daemon operatesentirely
+on event parameters and does not use sysfs for simple rules anymore.
+Please report any new bugs/problems, that may be caused by this big
+change. They will be fixed immediately.
+
+The enumeration format character '%e' is deprecated and will be
+removed sometimes from a future udev version. It never worked correctly
+outside of udevstart, so we can't use it with the new parallel
+coldplug. A simple enumeration is as useless as the devfs naming
+scheme, just get rid of both if you still use it.
+
+MODALIAS and $modalias is not needed and will be removed from one of
+the next udev versions, replace it in all rules with ENV{MODALIAS} or
+the sysfs "modalias" value.
+
+Thanks a lot to Marco for all his help on finding and fixing bugs.
+
+udev 079
+========
+Let scsi_id request libata drive serial numbers from page 0x80.
+
+Renamed etc/udev/persistent.rules to persistent-disk.rules and
+added /dev/disk/by-name/* for device mapper device names.
+
+Removed %e from the man page. It never worked reliably outside
+of udevstart and udevstart is no longer recommended to use.
+
+udev 078
+========
+Symlinks are now exported to the event environment. Hopefully it's no
+longer needed to run udevinfo from an event process, like it was
+mentioned on the hotplug list:
+ UDEV [1134776873.702967] add@/block/sdb
+ ...
+ DEVNAME=/dev/sdb
+ DEVLINKS=/dev/disk/by-id/usb-IBM_Memory_Key_0218B301030027E8 /dev/disk/by-path/usb-0218B301030027E8:0:0:0
+
+udev 077
+========
+Fix a problem if udevsend is used as the hotplug handler and tries to use
+syslog, which causes a "vc" event loop. 2.6.15 will make udevsend obsolete
+and this kind of problems will hopefully go away soon.
+
+udev 076
+========
+All built-in logic to work around bad sysfs timing is removed with this
+version. The need to wait for sysfs files is almost fixed with a kernel
+version that doesn't work with this udev version anyway. Until we fix
+the timing of the "bus" link creation, the former integrated logic should
+be emulated by a rule placed before all other rules:
+ ACTION=="add", DEVPATH=="/devices/*", ENV{PHYSDEVBUS}=="?*", WAIT_FOR_SYSFS="bus"
+
+The option "udev_db" does no longer exist. All udev state will be in
+/$udev_root/.udev/ now, there is no longer an option to set this
+to anything else.
+If the init script or something else used this value, just depend on
+this hardcoded path. But remember _all_content_ of this directory is
+still private to udev and can change at any time.
+
+Default location for rule sripts and helper programs is now: /lib/udev/.
+Everything that is not useful on the commandline should go into this
+directory. Some of the helpers in the extras folder are installed there
+now. The rules need to be changed, to find the helpers there.
+
+Also /lib/udev/devices is recommended as a directory where packages or
+the user can place real device nodes, which get copied over to /dev at
+every boot. This should replace the various solutions with custom config
+files.
+
+Udevsend does no longer start the udev daemon. This must be done with
+the init script that prepares /dev on tmpfs and creates the initial nodes,
+before starting the daemon.
+
+udev 075
+========
+Silent a too verbose error logging for the old hotplug.d/ dev.d/
+emulation.
+
+The copy of klibc is removed. A systemwide installed version of klibc
+should be used to build a klibc udev now.
+
+udev 074
+========
+NAME="" will not create any nodes, but execute RUN keys. To completely
+ignore an event the OPTION "ignore_device" should be used.
+
+After removal of the reorder queue, events with a TIMEOUT can be executed
+without any queuing now.
+
+udev 073
+========
+Fixed bug in udevd, if inotify is not available. We depend on netlink
+uevents now, kernels without that event source will not work with that
+version of udev anymore.
+
+udev 072
+========
+The rule parsing happens now in the daemon once at startup, all udev
+event processes inherit the already parsed rules from the daemon.
+It is shipped with SUSE10.0 and reduces heavily the system load at
+startup. The option to save precompiled rules and let the udev process
+pick the them up is removed, as it's no longer needed.
+
+Kernel 2.6.15 will have symlinks at /class/input pointing to the real
+device. Libsysfs is changed to "translate" the requested link into the
+real device path, as it would happen with the hotplug event. Otherwise
+device removal and the udev database will not work.
+
+Using 'make STRIPCMD=' will leave the binaries unstripped for debugging
+and packaging.
+
+A few improvements for vol_id, the filesytem probing code.
+
+udev 071
+========
+Fix a stupid typo in extras/run_directory for "make install".
+
+scsi_id creates the temporary devnode now in /dev for usage with a
+non-writable /tmp directory.
+
+The uevent kernel socket buffer can carry app. 50.000 events now,
+let's see who can break this again. :)
+
+The upcoming kernel will have a new input driver core integration.
+Some class devices are now symlinks to the real device. libsysfs
+needs a fix for this to work correctly. Udevstart of older udev
+versions will _not_ create these devices!
+
+udev 070
+========
+Fix a 'install' target in the Makefile, that prevents EXTRAS from
+beeing installed.
+
+udev 069
+========
+A bunch of mostly trivial bugfixes. From now on no node name or
+symlink name can contain any character than plain whitelisted ascii
+characters or validated utf8 byte-streams. This is needed for the
+/dev/disk/by-label/* links, because we import untrusted data and
+export it to the filesystem.
+
+udev 068
+========
+More bugfixes. If udevd was started from the kernel, we don't
+have stdin/stdout/stderr, which broke the forked tools in some
+situations.
+
+udev 067
+========
+Bugfix. udevstart event ordering was broken for a long time.
+The new run_program() uncovered it, because /dev/null was not
+available while we try to run external programs.
+Now udevstart should create it before we run anything.
+
+udev 066
+========
+Minor bugfixes and some distro rules updates. If you don't have the
+persistent disk rules in /dev/disk/by-*/* on your distro, just
+grab it from here. :)
+
+udev 065
+========
+We can use socket communication now to pass events from udev to
+other programs:
+ RUN+="socket:/org/freedesktop/hal/udev_event"
+will pass the whole udev event to the HAL daemon without the need
+for a forked helper. (See ChangeLog for udevmonitor, as an example)
+
+udev 064
+========
+Mostly bugfixes and see ChangeLog.
+
+The test for the existence of an environment value should be
+switched from:
+ ENV{KEY}=="*" to ENV{KEY}=="?*"
+because "*" will not fail anymore, if the key does not exist or
+is empty.
+
+udev 063
+========
+Bugfixes and a few tweaks described in the ChangeLog.
+
+udev 062
+========
+Mostly a Bugfix release.
+
+Added WAIT_FOR_SYSFS="<attribute>" to be able to fight against the sysfs
+timing with custom rules.
+
+udev 061
+========
+We changed the internal rule storage format. Our large rule files took
+2 MB of RAM, with the change we are down to 99kB.
+
+If the device-node has been created with default name and no symlink or
+options are to remenber, it is not longer stored in the udevdb. HAL will
+need to be updated to work correctly with that change.
+
+To overrride optimization flags, OPTFLAGS may be used now.
+
+udev 060
+========
+Bugfix release.
+
+udev 059
+========
+Major changes happened with this release. The goal is to take over the
+complete kernel-event handling and provide a more efficient way to dispatch
+kernel events. Replacing most of the current shell script logic and the
+kernel forked helper with a netlink-daemon and a rule-based event handling.
+
+o udevd listens to netlink events now. The first valid netlink event
+ will make udevd ignore any message from udevsend that contains a
+ SEQNUM, to avoid duplicate events. The forked events can be disabled
+ with:
+ echo "" > /proc/sys/kernel/hotplug
+ For full support, the broken input-subsytem needs to be fixed, not to
+ bypass the driver core.
+
+o /etc/dev.d/ + /etc/hotplug.d/ directory multiplexing is completely
+ removed from udev itself and must be emulated by calling small
+ helper binaries provided in the extras folder:
+ make EXTRAS=extras/run_directory/
+ will build udev_run_devd and udev_run_hotplugd, which can be called
+ from a rule if needed:
+ RUN+="/sbin/udev_run_hotplugd"
+ The recommended way to handle this is to convert all the calls from
+ the directories to explicit udev rules and get completely rid of the
+ multiplexing. (To catch a ttyUSB event, you now no longer need to
+ fork and exit 300 tty script instances you are not interested in, it
+ is just one rule that matches exactly the device.)
+
+o udev handles now _all_ events not just events for class and block
+ devices, this way it is possible to control the complete event
+ behavior with udev rules. Especially useful for rules like:
+ ACTION="add", DEVPATH="/devices/*", MODALIAS=="?*", RUN+="/sbin/modprobe $modalias"
+
+o As used in the modalias rule, udev supports now textual
+ substitution placeholder along with the usual format chars. This
+ needs to be documented, for now it's only visible in udev_rules_parse.c.
+
+o The rule keys support now more operations. This is documented in the
+ man page. It is possible to add values to list-keys like the SYMLINK
+ and RUN list with KEY+="value" and to clear the list by assigning KEY="".
+ Also "final"-assignments are supported by using KEY:="value", which will
+ prevent changing the key by any later rule.
+
+o kernel 2.6.12 has the "detached_state" attribute removed from
+ sysfs, which was used to recognize sysfs population. We switched that
+ to wait for the "bus" link, which is only available in kernels after 2.6.11.
+ Running this udev version on older kernels may cause a short delay for
+ some events.
+
+o To provide infrastructure for persistent device naming, the id programs:
+ scsi_id, vol_id (former udev_volume_id), and ata_id (new) are able now
+ to export the probed data in environment key format:
+ pim:~ # /sbin/ata_id --export /dev/hda
+ ID_MODEL=HTS726060M9AT00
+ ID_SERIAL=MRH401M4G6UM9B
+ ID_REVISION=MH4OA6BA
+
+ The following rules:
+ KERNEL="hd*[!0-9]", IMPORT="/sbin/ata_id --export $tempnode"
+ KERNEL="hd*[!0-9]", ENV{ID_SERIAL}=="?*", SYMLINK+="disk/by-id/$env{ID_MODEL}_$env{ID_SERIAL}"
+
+ Will create:
+ kay@pim:~> tree /dev/disk
+ /dev/disk
+ |-- by-id
+ | |-- HTS726060M9AT00_MRH401M4G6UM9B -> ../../hda
+ | `-- IBM-Memory_Key -> ../../sda
+ |-- by-label
+ | |-- swap -> ../../hda1
+ | |-- date -> ../../sda1
+ | `-- home -> ../../hda3
+ `-- by-uuid
+ |-- 2E08712B0870F2E7 -> ../../hda3
+ |-- 9352cfef-7687-47bc-a2a3-34cf136f72e1 -> ../../hda1
+ |-- E845-7A89 -> ../../sda1
+ `-- b2a61681-3812-4f13-a4ff-920d70604299 -> ../../hda2
+
+ The IMPORT= operation will import these keys in the environment and make
+ it available for later PROGRAM= and RUN= executed programs. The keys are
+ also stored in the udevdb and can be queried from there with one of the
+ next udev versions.
+
+o A few binaries are silently added to the repository, which can be used
+ to replay kernel events from initramfs instead of using coldplug. udevd
+ can be instructed now to queue-up events while the stored events from
+ initramfs are filled into the udevd-queue. This code is still under
+ development and there is no documentation now besides the code itself.
+ The additional binaries get compiled, but are not installed by default.
+
+o There is also a temporary fix for a performance problem where too many
+ events happen in parallel and every event needs to parse the rules.
+ udev can now read precompiled rules stored on disk. This is likely to be
+ replaced by a more elegant solution in a future udev version.
+
+udev 058
+========
+With kernel version 2.6.12, the sysfs file "detached_state" was removed.
+Fix for libsysfs not to expect this file was added.
+
+udev 057
+========
+All rules are applied now, but only the first matching rule with a NAME-key
+will be applied. All later rules with NAME-key are completely ignored. This
+way system supplied symlinks or permissions gets applied to user-defined
+naming rules.
+
+Note:
+Please check your rules setup, if you may need to add OPTIONS="last_rule"
+to some rules, to keep the old behavior.
+
+The rules are read on "remove"-events too. That makes is possible to match
+with keys that are available on remove (KERNEL, SUBSYSTEM, ID, ENV, ...) to
+instruct udev to ignore an event (OPTIONS="ignore_device").
+The new ACTION-key may be used to let a rule act only at a "remove"-event.
+
+The new RUN-key supports rule-based execution of programs after device-node
+handling. This is meant as a general replacement for the dev.d/-directories
+to give fine grained control over the execution of programs.
+
+The %s{}-sysfs format char replacement values are searched at any of the
+devices in the device chain now, not only at the class-device.
+
+We support log priority levels now. The value udev_log in udev.conf is used
+to determine what is printed to syslog. This makes it possible to
+run a version with compiled-in debug messages in a production environment
+which is sometimes needed to find a bug.
+It is still possible to supress the inclusion of _any_ syslog usage with
+USE_LOG=false to create the smallest possible binaries if needed.
+The configured udev_log value can be overridden with the environment variable
+UDEV_LOG.
+
+udev 056
+========
+Possible use of a system-wide klibc:
+ make USE_KLIBC=true KLCC=/usr/bin/klcc all
+will link against an external klibc and our own version will be ignored.
+
+udev 055
+========
+We support an unlimited count of symlinks now.
+
+If USE_STATIC=true is passed to a glibc build, we link statically and use
+a built-in userdb parser to resolve user and group names.
+
+The PLACE= key is gone. It can be replaced by an ID= for a long time, because
+we walk up the chain of physical devices to find a match.
+
+The KEY="<value>" format supports '=', '==', '!=,' , '+=' now. This makes it
+easy to skip certain attribute matches without composing rules with weird

+udev - Linux userspace device management
+
+Integrating udev in the system has complex dependencies and may differ from
+distribution to distribution. A system may not be able to boot up or work
+reliably without a properly installed udev version. The upstream udev project
+does not recommend replacing a distro's udev installation with the upstream
+version.
+
+The upstream udev project's set of default rules may require a most recent
+kernel release to work properly.
+
+Tools and rules shipped by udev are not public API and may change at any time.
+Never call any private tool in /usr/lib/udev from any external application; it
+might just go away in the next release. Access to udev information is only offered
+by udevadm and libudev. Tools and rules in /usr/lib/udev and the entire contents
+of the /run/udev directory are private to udev and do change whenever needed.
+
+Requirements:
+ - Version 2.6.34 of the Linux kernel with sysfs, procfs, signalfd, inotify,
+ unix domain sockets, networking and hotplug enabled
+
+ - Some architectures might need a later kernel, that supports accept4(),
+ or need to backport the accept4() syscall wiring in the kernel.
+
+ - These options are required:
+ CONFIG_DEVTMPFS=y
+ CONFIG_HOTPLUG=y
+ CONFIG_INOTIFY_USER=y
+ CONFIG_NET=y
+ CONFIG_PROC_FS=y
+ CONFIG_SIGNALFD=y
+ CONFIG_SYSFS=y
+ CONFIG_SYSFS_DEPRECATED*=n
+ CONFIG_UEVENT_HELPER_PATH=""
+
+ - These options might be needed:
+ CONFIG_BLK_DEV_BSG=y (SCSI devices)
+ CONFIG_TMPFS_POSIX_ACL=y (user ACLs for device nodes)
+
+ - The /dev directory needs the 'devtmpfs' filesystem mounted.
+ Udev only manages the permissions and ownership of the
+ kernel-provided device nodes, and possibly creates additional symlinks.
+
+ - Udev requires /run to be writable, which is usually done by mounting a
+ 'tmpfs' filesystem.
+
+ - This version of udev does not work properly with the CONFIG_SYSFS_DEPRECATED*
+ option enabled.
+
+ - The deprecated hotplug helper /sbin/hotplug should be disabled in the
+ kernel configuration, it is not needed today, and may render the system
+ unusable because the kernel may create too many processes in parallel
+ so that the system runs out-of-memory.
+
+ - The proc filesystem must be mounted on /proc, and the sysfs filesystem must
+ be mounted at /sys. No other locations are supported by a standard
+ udev installation.
+
+ - The default rule sset requires the following group names resolvable at udev startup:
+ disk, cdrom, floppy, tape, audio, video, lp, tty, dialout, and kmem.
+ Especially in LDAP setups, it is required that getgrnam() be able to resolve
+ these group names with only the rootfs mounted and while no network is
+ available.
+
+ - Some udev extras have external dependencies like:
+ libglib2, usbutils, pciutils, and gperf.
+ All these extras can be disabled with configure options.
+
+Setup:
+ - The udev daemon should be started to handle device events sent by the kernel.
+ During bootup, the events for already existing devices can be replayed, so
+ that they are configured by udev. The systemd service files contain the
+ needed commands to start the udev daemon and the coldplug sequence.
+
+ - Restarting the daemon never applies any rules to existing devices.
+
+ - New/changed rule files are picked up automatically; there is usually no
+ daemon restart or signal needed.
+
+Operation:
+ - Based on events the kernel sends out on device creation/removal, udev
+ creates/removes device nodes and symlinks in the /dev directory.
+
+ - All kernel events are matched against a set of specified rules, which
+ possibly hook into the event processing and load required kernel
+ modules to set up devices. For all devices, the kernel exports a major/minor
+ number; if needed, udev creates a device node with the default kernel
+ device name. If specified, udev applies permissions/ownership to the device
+ node, creates additional symlinks pointing to the node, and executes
+ programs to handle the device.
+
+ - The events udev handles, and the information udev merges into its device
+ database, can be accessed with libudev:
+ http://www.kernel.org/pub/linux/utils/kernel/hotplug/libudev/
+ http://www.kernel.org/pub/linux/utils/kernel/hotplug/gudev/
+
+For more details about udev and udev rules, see the udev man pages:
+ http://www.kernel.org/pub/linux/utils/kernel/hotplug/udev/
+
+Please direct any comment/question to the linux-hotplug mailing list at:
+ linux-hotplug@vger.kernel.org

+# Ok, we probably need a little explanation here for what the two lines above
+# are good for.
+#
+# The story goes like this: when ALSA registers a new sound card it emits a
+# series of 'add' events to userspace, for the main card device and for all the
+# child device nodes that belong to it. udev relays those to applications,
+# however only maintains the order between father and child, but not between
+# the siblings. The control device node creation can be used as synchronization
+# point. All other devices that belong to a card are created in the kernel
+# before it. However unfortunately due to the fact that siblings are forwarded
+# out of order by udev this fact is lost to applications.
+#
+# OTOH before an application can open a device it needs to make sure that all
+# its device nodes are completely created and set up.
+#
+# As a workaround for this issue we have added the udev rule above which will
+# generate a 'change' event on the main card device from the 'add' event of the
+# card's control device. Due to the ordering semantics of udev this event will
+# only be relayed after all child devices have finished processing properly.
+# When an application needs to listen for appearing devices it can hence look
+# for 'change' events only, and ignore the actual 'add' events.
+#
+# When the application is initialized at the same time as a device is plugged
+# in it may need to figure out if the 'change' event has already been triggered
+# or not for a card. To find that out we store the flag environment variable
+# SOUND_INITIALIZED on the device which simply tells us if the card 'change'
+# event has already been processed.

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+ This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it. You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+ When we speak of free software, we are referring to freedom of use,
+not price. Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+ To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+there is no warranty for the free library. Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+ Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder. Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License. This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License. We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom. The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+ We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard. To achieve this, non-free programs must be
+allowed to use the library. A more frequent case is that a free
+library does the same job as widely used non-free libraries. In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software. For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+ Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+ 6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a
+ copy of the library already present on the user's computer system,
+ rather than copying library functions into the executable, and (2)
+ will operate properly with a modified version of the library, if
+ the user installs one, as long as the modified version is
+ interface-compatible with the version that the work was made with.
+
+ c) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ d) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ e) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+ 11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded. In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission. For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this. Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the library's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>

+Also add information on how to contact you by electronic and paper mail.

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+ This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it. You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+ When we speak of free software, we are referring to freedom of use,
+not price. Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+ To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+there is no warranty for the free library. Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+ Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder. Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License. This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License. We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom. The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+ We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard. To achieve this, non-free programs must be
+allowed to use the library. A more frequent case is that a free
+library does the same job as widely used non-free libraries. In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software. For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+ Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+ 6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a
+ copy of the library already present on the user's computer system,
+ rather than copying library functions into the executable, and (2)
+ will operate properly with a modified version of the library, if
+ the user installs one, as long as the modified version is
+ interface-compatible with the version that the work was made with.
+
+ c) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ d) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ e) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+ 11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded. In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission. For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this. Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the library's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This library is free software; you can redistribute it and/or
+ modify it under the terms of the GNU Lesser General Public
+ License as published by the Free Software Foundation; either
+ version 2.1 of the License, or (at your option) any later version.
+
+ This library is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
+ Lesser General Public License for more details.
+
+ You should have received a copy of the GNU Lesser General Public
+ License along with this library; if not, write to the Free Software
+ Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the
+ library `Frob' (a library for tweaking knobs) written by James Random Hacker.

+ * @short_description: Query devices and listen to uevents
+ *
+ * #GUdevClient is used to query information about devices on a Linux
+ * system from the Linux kernel and the udev device
+ * manager.
+ *
+ * Device information is retrieved from the kernel (through the
+ * <literal>sysfs</literal> filesystem) and the udev daemon (through a
+ * <literal>tmpfs</literal> filesystem) and presented through
+ * #GUdevDevice objects. This means that no blocking IO ever happens
+ * (in both cases, we are essentially just reading data from kernel
+ * memory) and as such there are no asynchronous versions of the
+ * provided methods.
+ *
+ * To get #GUdevDevice objects, use
+ * g_udev_client_query_by_subsystem(),
+ * g_udev_client_query_by_device_number(),
+ * g_udev_client_query_by_device_file(),
+ * g_udev_client_query_by_sysfs_path(),
+ * g_udev_client_query_by_subsystem_and_name()
+ * or the #GUdevEnumerator type.
+ *
+ * To listen to uevents, connect to the #GUdevClient::uevent signal.

+ * SECTION:gudevdevice
+ * @short_description: Get information about a device
+ *
+ * The #GUdevDevice class is used to get information about a specific
+ * device. Note that you cannot instantiate a #GUdevDevice object
+ * yourself. Instead you must use #GUdevClient to obtain #GUdevDevice
+ * objects.
+ *
+ * To get basic information about a device, use
+ * g_udev_device_get_subsystem(), g_udev_device_get_devtype(),
+ * g_udev_device_get_name(), g_udev_device_get_number(),
+ * g_udev_device_get_sysfs_path(), g_udev_device_get_driver(),
+ * g_udev_device_get_action(), g_udev_device_get_seqnum(),
+ * g_udev_device_get_device_type(), g_udev_device_get_device_number(),
+ * g_udev_device_get_device_file(),
+ * g_udev_device_get_device_file_symlinks().
+ *
+ * To navigate the device tree, use g_udev_device_get_parent() and
+ * g_udev_device_get_parent_with_subsystem().
+ *
+ * To access udev properties for the device, use
+ * g_udev_device_get_property_keys(),
+ * g_udev_device_has_property(),
+ * g_udev_device_get_property(),
+ * g_udev_device_get_property_as_int(),
+ * g_udev_device_get_property_as_uint64(),
+ * g_udev_device_get_property_as_double(),
+ * g_udev_device_get_property_as_boolean() and
+ * g_udev_device_get_property_as_strv().
+ *
+ * To access sysfs attributes for the device, use
+ * g_udev_device_get_sysfs_attr(),
+ * g_udev_device_get_sysfs_attr_as_int(),
+ * g_udev_device_get_sysfs_attr_as_uint64(),
+ * g_udev_device_get_sysfs_attr_as_double(),
+ * g_udev_device_get_sysfs_attr_as_boolean() and
+ * g_udev_device_get_sysfs_attr_as_strv().
+ *
+ * Note that all getters on #GUdevDevice are non-reffing – returned
+ * values are owned by the object, should not be freed and are only
+ * valid as long as the object is alive.
+ *
+ * By design, #GUdevDevice will not react to changes for a device – it
+ * only contains a snapshot of information when the #GUdevDevice
+ * object was created. To work with changes, you typically connect to
+ * the #GUdevClient::uevent signal on a #GUdevClient and get a new
+ * #GUdevDevice whenever an event happens.

+= The udev keymap tool =
+
+== Introduction ==
+
+This udev extension configures computer model specific key mappings. This is
+particularly necessary for the non-standard extra keys found on many laptops,
+such as "brightness up", "next song", "www browser", or "suspend". Often these
+are accessed with the Fn key.
+
+Every key produces a "scan code", which is highly vendor/model specific for the
+nonstandard keys. This tool maintains mappings for these scan codes to standard
+"key codes", which denote the "meaning" of the key. The key codes are defined
+in /usr/include/linux/input.h.
+
+If some of your keys on your keyboard are not working at all, or produce the
+wrong effect, then a very likely cause of this is that the scan code -> key
+code mapping is incorrect on your computer.
+
+== Structure ==
+
+udev-keymap consists of the following parts:
+
+ keymaps/*:: mappings of scan codes to key code names
+
+ 95-keymap.rules:: udev rules for mapping system vendor/product names and
+ input module names to one of the keymaps above
+
+ keymap:: manipulate an evdev input device:
+ * write a key map file into a device (used by udev rules)
+ * dump current scan → key code mapping
+ * interactively display scan and key codes of pressed keys
+
+ findkeyboards:: display evdev input devices which belong to actual keyboards,
+ i. e. those suitable for the keymap program
+
+ fdi2rules.py:: convert hal keymap FDIs into udev rules and key map files
+ (Please note that this is far from perfect, since the mapping between fdi and
+ udev rules is not straightforward, and impossible in some cases.)
+
+== Fixing broken keys ==
+
+In order to make a broken key work on your system and send it back to upstream
+for inclusion you need to do the following steps:
+
+ 1. Find the keyboard device.
+
+ Run /usr/lib/udev/findkeyboards. This should always give you an "AT
+ keyboard" and possibly a "module". Some laptops (notably Thinkpads, Sonys, and
+ Acers) have multimedia/function keys on a separate input device instead of the
+ primary keyboard. The keyboard device should have a name like "input/event3".
+ In the following commands, the name will be written as "input/eventX" (replace
+ X with the appropriate number).
+
+ 2. Find broken scan codes:
+
+ sudo /usr/lib/udev/keymap -i input/eventX
+
+ Press all multimedia/function keys and check if the key name that gets printed
+ out is plausible. If it is unknown or wrong, write down the scan code (looks
+ like "0x1E") and the intended functionality of this key. Look in
+ /usr/include/linux/input.h for an available KEY_XXXXX constant which most
+ closely approximates this functionality and write it down as the new key code.
+
+ For example, you might press a key labeled "web browser" which currently
+ produces "unknown". Note down this:
+
+ 0x1E www # Fn+F2 web browser
+
+ Repeat that for all other keys. Write the resulting list into a file. Look at
+ /usr/lib/udev/keymaps/ for existing key map files and make sure that you use the
+ same structure.
+
+ If the key only ever works once and then your keyboard (or the entire desktop)
+ gets stuck for a long time, then it is likely that the BIOS fails to send a
+ corresponding "key release" event after the key press event. Please note down
+ this case as well, as it can be worked around in
+ /usr/lib/udev/keymaps/95-keyboard-force-release.rules .
+
+ 3. Find out your system vendor and product:
+
+ cat /sys/class/dmi/id/sys_vendor
+ cat /sys/class/dmi/id/product_name
+
+ 4. Generate a device dump with "udevadm info --export-db > /tmp/udev-db.txt".
+
+ 6. Send the system vendor/product names, the key mapping from step 2,
+ and /tmp/udev-db.txt from step 4 to the linux-hotplug@vger.kernel.org mailing
+ list, so that they can be included in the next release.
+
+For local testing, copy your map file to /usr/lib/udev/keymaps/ with an appropriate
+name, and add an appropriate udev rule to /usr/lib/udev/rules.d/95-keymap.rules:
+
+ * If you selected an "AT keyboard", add the rule to the section after
+ 'LABEL="keyboard_vendorcheck"'.
+
+ * If you selected a "module", add the rule to the top section where the
+ "ThinkPad Extra Buttons" are.
+

+ * DISCLAIMER - The file format mentioned here is private to udev/libudev,
+ * and may be changed without notice.
+ *
+ * The udev event queue is exported as a binary log file.
+ * Each log record consists of a sequence number followed by the device path.
+ *
+ * When a new event is queued, its details are appended to the log.
+ * When the event finishes, a second record is appended to the log
+ * with the same sequence number but a devpath len of 0.
+ *
+ * Example:
+ * { 0x0000000000000001 }
+ * { 0x0000000000000001, 0x0019, "/devices/virtual/mem/null" },
+ * { 0x0000000000000002, 0x001b, "/devices/virtual/mem/random" },
+ * { 0x0000000000000001, 0x0000 },
+ * { 0x0000000000000003, 0x0019, "/devices/virtual/mem/zero" },
+ *
+ * Events 2 and 3 are still queued, but event 1 has finished.
+ *
+ * The queue does not grow indefinitely. It is periodically re-created
+ * to remove finished events. Atomic rename() makes this transparent to readers.
+ *
+ * The queue file starts with a single sequence number which specifies the
+ * minimum sequence number in the log that follows. Any events prior to this
+ * sequence number have already finished.

+.TH SCSI_ID 8 "December 2003" "" "Linux Administrator's Manual"
+.SH NAME
+scsi_id \- retrieve and generate a unique SCSI identifier
+.SH SYNOPSIS
+.BI scsi_id
+[\fIoptions\fP]
+.SH "DESCRIPTION"
+.B scsi_id
+queries a SCSI device via the SCSI INQUIRY vital product data (VPD) page 0x80 or
+0x83 and uses the resulting data to generate a value that is unique across
+all SCSI devices that properly support page 0x80 or page 0x83.
+
+If a result is generated it is sent to standard output, and the program
+exits with a zero value. If no identifier is output, the program exits
+with a non\-zero value.
+
+\fBscsi_id\fP is primarily for use by other utilities such as \fBudev\fP
+that require a unique SCSI identifier.
+
+By default all devices are assumed black listed, the \fB\-\-whitelisted\fP option must
+be specified on the command line or in the config file for any useful
+behaviour.
+
+SCSI commands are sent directly to the device via the SG_IO ioctl
+interface.
+
+In order to generate unique values for either page 0x80 or page 0x83, the
+serial numbers or world wide names are prefixed as follows.
+
+Identifiers based on page 0x80 are prefixed by the character 'S', the SCSI
+vendor, the SCSI product (model) and then the the serial number returned
+by page 0x80. For example:
+
+.sp
+.nf
+# /usr/lib/udev/scsi_id \-\-page=0x80 \-\-whitelisted \-\-device=/dev/sda
+SIBM 3542 1T05078453
+.fi
+.P
+
+Identifiers based on page 0x83 are prefixed by the identifier type
+followed by the page 0x83 identifier. For example, a device with a NAA
+(Name Address Authority) type of 3 (also in this case the page 0x83
+identifier starts with the NAA value of 6):
+
+.sp
+.nf
+# /usr/lib/udev/scsi_id \-\-page=0x83 \-\-whitelisted \-\-device=/dev/sda
+3600a0b80000b174b000000d63efc5c8c
+.fi
+.P
+
+.SH OPTIONS
+.TP
+.BI \-\-blacklisted
+The default behaviour \- treat the device as black listed, and do nothing
+unless a white listed device is found in the scsi_id config\-file.
+.TP
+.BI \-\-device=\| device\^
+Send SG_IO commands to \fBdevice\fP, such as \fB/dev/sdc\fP.
+.TP
+.BI \-\-config=\| config\-file
+Read configuration and black/white list entries from
+.B config\-file
+rather than the default
+.B /etc/scsi_id.config
+file.
+.TP
+.BI \-\-whitelisted
+Treat the device as white listed. The \fB\-\-whitelisted\fP option must be specified
+on the command line or in the scsi_id configuration file for
+.B scsi_id
+to generate any output.
+.TP
+.BI \-\-page=\| 0x80 | 0x83 | pre-spc3-83
+Use SCSI INQUIRY VPD page code 0x80, 0x83, or pre-spc3-83.
+.sp
+The default
+behaviour is to query the available VPD pages, and use page 0x83 if found,
+else page 0x80 if found, else nothing.
+.sp
+Page pre-spc3-83 should only be utilized for those scsi devices which
+are not compliant with the SPC-2 or SPC-3 format for page 83. While this
+option is used for older model 4, 5, and 6 EMC Symmetrix devices, its
+use with SPC-2 or SPC-3 compliant devices will fallback to the page 83
+format supported by these devices.
+.TP
+.BI \-\-replace-whitespace
+Reformat the output : replace all whitespaces by underscores.
+.TP
+.BI \-\-export
+Export all data in KEY=<value> format used to import in other programs.
+.TP
+.BI \-\-verbose
+Generate verbose debugging output.
+.TP
+.BI \-\-version
+Display version number and exit.

+ Reference implementation of a few systemd related interfaces for
+ writing daemons. These interfaces are trivial to implement. To
+ simplify porting we provide this reference implementation.
+ Applications are welcome to reimplement the algorithms described
+ here if they do not want to include these two source files.
+
+ The following functionality is provided:
+
+ - Support for logging with log levels on stderr
+ - File descriptor passing for socket-based activation
+ - Daemon startup and status notification
+ - Detection of systemd boots
+
+ You may compile this with -DDISABLE_SYSTEMD to disable systemd
+ support. This makes all those calls NOPs that are directly related to
+ systemd (i.e. only sd_is_xxx() will stay useful).
+
+ Since this is drop-in code we don't want any of our symbols to be
+ exported in any case. Hence we declare hidden visibility for all of
+ them.
+
+ You may find an up-to-date version of these source files online:
+
+ http://cgit.freedesktop.org/systemd/systemd/plain/src/systemd/sd-daemon.h
+ http://cgit.freedesktop.org/systemd/systemd/plain/src/sd-daemon.c
+
+ This should compile on non-Linux systems, too, but with the
+ exception of the sd_is_xxx() calls all functions will become NOPs.

+ fork off the process itself. Example: "MAINPID=4711"
+
+ WATCHDOG=1 Tells systemd to update the watchdog timestamp.
+ Services using this feature should do this in
+ regular intervals. A watchdog framework can use the
+ timestamps to detect failed services.
+
+ Daemons can choose to send additional variables. However, it is
+ recommended to prefix variable names not listed above with X_.
+
+ Returns a negative errno-style error code on failure. Returns > 0
+ if systemd could be notified, 0 if it couldn't possibly because
+ systemd is not running.
+
+ Example: When a daemon finished starting up, it could issue this
+ call to notify systemd about it:
+
+ sd_notify(0, "READY=1");
+
+ See sd_notifyf() for more complete examples.
+
+ See sd_notify(3) for more information.
+*/

+ Similar to sd_notify() but takes a format string.
+
+ Example 1: A daemon could send the following after initialization:
+
+ sd_notifyf(0, "READY=1\n"
+ "STATUS=Processing requests...\n"
+ "MAINPID=%lu",
+ (unsigned long) getpid());
+
+ Example 2: A daemon could send the following shortly before
+ exiting, on failure:
+
+ sd_notifyf(0, "STATUS=Failed to start up: %s\n"
+ "ERRNO=%i",
+ strerror(errno),
+ errno);

+ that all of the functions above handle non-systemd boots just
+ fine. You should NOT protect them with a call to this function. Also
+ note that this function checks whether the system, not the user

+ <refsect1><title>Description</title>
+ <para>udev supplies the system software with device events, manages permissions
+ of device nodes and may create additional symlinks in the <filename>/dev</filename>
+ directory, or renames network interfaces. The kernel usually just assigns unpredictable
+ device names based on the order of discovery. Meaningful symlinks or network device
+ names provide a way to reliably identify devices based on their properties or
+ current configuration.</para>
+
+ <para>The udev daemon, <citerefentry><refentrytitle>udevd</refentrytitle>
+ <manvolnum>8</manvolnum></citerefentry>, receives device uevents directly from
+ the kernel whenever a device is added or removed from the system, or it changes its
+ state. When udev receives a device event, it matches its configured set of rules
+ against various device attributes to identify the device. Rules that match may
+ provide additional device information to be stored in the udev database or
+ to be used to create meaningful symlink names.</para>
+
+ <para>All device information udev processes is stored in the udev database and
+ sent out to possible event subscribers. Access to all stored data and the event
+ sources is provided by the library libudev.</para>
+ </refsect1>
+
+ <refsect1><title>Configuration</title>
+ <para>udev configuration files are placed in <filename>/etc/udev</filename>
+ and <filename>/usr/lib/udev</filename>. All empty lines or lines beginning with
+ '#' are ignored.</para>
+
+ <refsect2><title>Configuration file</title>
+ <para>udev expects its main configuration file at <filename>/etc/udev/udev.conf</filename>.
+ It consists of a set of variables allowing the user to override default udev values.
+ The following variables can be set:</para>
+ <variablelist>
+ <varlistentry>
+ <term><option>udev_root</option></term>
+ <listitem>
+ <para>Specifies where to place the device nodes in the filesystem.
+ The default value is <filename>/dev</filename>.</para>
+ </listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term><option>udev_log</option></term>
+ <listitem>
+ <para>The logging priority. Valid values are the numerical syslog priorities
+ or their textual representations: <option>err</option>, <option>info</option>
+ and <option>debug</option>.</para>
+ </listitem>
+ </varlistentry>
+ </variablelist>
+ </refsect2>
+
+ <refsect2><title>Rules files</title>
+ <para>The udev rules are read from the files located in the
+ system rules directory <filename>/usr/lib/udev/rules.d</filename>,
+ the volatile runtime directory <filename>/run/udev/rules.d</filename>
+ and the local administration directory <filename>/etc/udev/rules.d</filename>.
+ All rules files are collectively sorted and processed in lexical order,
+ regardless of the directories in which they live. However, files with
+ identical file names replace each other. Files in <filename>/etc</filename>
+ have the highest priority, files in <filename>/run</filename> take precedence
+ over files with the same name in <filename>/lib</filename>. This can be
+ used to override a system-supplied rules file with a local file if needed;
+ a symlink in <filename>/etc</filename> with the same name as a rules file in
+ <filename>/lib</filename>, pointing to <filename>/dev/null</filename>,
+ disables the rules file entirely.</para>
+
+ <para>Rule files must have the extension <filename>.rules</filename>; other
+ extensions are ignored.</para>
+
+ <para>Every line in the rules file contains at least one key-value pair.
+ There are two kind of keys: match and assignment.
+ If all match keys are matching against its value, the rule gets applied and the
+ assignment keys get the specified value assigned.</para>
+
+ <para>A matching rule may rename a network interface, add symlinks
+ pointing to the device node, or run a specified program as part of
+ the event handling.</para>
+
+ <para>A rule consists of a comma-separated list of one or more key-value pairs.
+ Each key has a distinct operation, depending on the used operator. Valid
+ operators are:</para>
+ <variablelist>
+ <varlistentry>
+ <term><option>==</option></term>
+ <listitem>
+ <para>Compare for equality.</para>
+ </listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term><option>!=</option></term>
+ <listitem>
+ <para>Compare for inequality.</para>
+ </listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term><option>=</option></term>
+ <listitem>
+ <para>Assign a value to a key. Keys that represent a list are reset
+ and only this single value is assigned.</para>
+ </listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term><option>+=</option></term>

+ <term><option>:=</option></term>
+ <listitem>
+ <para>Assign a value to a key finally; disallow any later changes.</para>
+ </listitem>
+ </varlistentry>
+ </variablelist>
+
+ <para>The following key names can be used to match against device properties.
+ Some of the keys also match against properties of the parent devices in sysfs,
+ not only the device that has generated the event. If multiple keys that match
+ a parent device are specified in a single rule, all these keys must match at
+ one and the same parent device.</para>

+# udev test
+#
+# Provides automated testing of the udev binary.
+# The whole test is self contained in this file, except the matching sysfs tree.
+# Simply extend the @tests array, to add a new test variant.
+#
+# Every test is driven by its own temporary config file.
+# This program prepares the environment, creates the config and calls udev.
+#
+# udev parses the rules, looks at the provided sysfs and
+# first creates and then removes the device node.
+# After creation and removal the result is checked against the
+# expected value and the result is printed.
