Example for /block/sda:
SUBSYSTEMS="scsi", ENV{COMMENT}="$attr{driver}"
sets COMMENT=sd
SUBSYSTEMS="pci", ENV{COMMENT}="$attr{driver}"
sets COMMENT=ata_piix

devices
This scheme is more consistent and makes it obvious if a match happens
against the event device only, or the full chain of parent devices.
The old key names are now:
BUS -> SUBSYSTEMS
ID -> KERNELS
SYSFS -> ATTRS
DRIVER -> DRIVERS
Match keys for the event device:
KERNEL
SUBSYSTEM
ATTR
DRIVER (in a future release, for now the same as DRIVERS)
Match keys for all devices along the parent device chain:
KERNELS
SUBSYSTEMS
ATTRS
DRIVERS
ID, BUS, SYSFS are no longer mentioned in the man page but still work.
DRIVER must be converted to DRIVERS to match the new scheme. For now,
an error is logged, if DRIVER is used. In a future release, the DRIVER
key behaviour will change.

Consecutive "add" events will not remove and recreate the same symlinks
anymore. No longer valid links, like after changing a filesystem label,
will still be removed.

We never used any of the libsysfs convenience features. Here we replace
it completely with 300 lines of code, which are much simpler and a bit
faster cause udev(d) does not open any syfs file for a simple event which
does not need any parent device information.

All udev state is kept in /$udev_root/.udev/ now. No option to
configure that anymore, it will always be there.

No device node or symlink can have other characters as plain
readable ascii or valid utf8. The /dev/disk/by-label/* symlinks
can no longer contain weird stuff read from untrusted sources.

This can be uses to export stuff to the event environment or
to carry a state from one rule to another, like enabling/disabling
later rules conditionally.

This will allow us to have whole blocks of rules to skip
conditionally. The following section creates the node "yes":
GOTO="TEST"
NAME="no"
NAME="no2", LABEL="NO"
NAME="yes", LABEL="TEST"
NAME="no3"

This allows to source-in a file into the udev environment to have
the defined keys available for later processing by udev itself or
the forked helper programs.

Former values are cleared if SYMLINK=<value> is used. To add a value
SYMLINK+=<value> is now needed.

The use of KEY:=<value> will make the key unchangeable by later rules.

Yeah, I guess it's broken. In create_node() in udev_add.c there is
always added 1 to the minor number, thus the error. The attached patch
should fix this.

SUBSYSTEM=="block", RUN="/sbin/program"
will execute the program only for block device events.
ACTION="remove", SUBSYSTEM=="block", RUN"/sbin/program"
will execute the program, if a block device is removed.

Better remove characters that are useless in a device node name.
It may be a security risk to pass any character read from e.g. a
sysfs attribute to a shell script we execute later.
Prevent the modification of the libsysfs attribute value
cache.
Clear PROGRAM result if the execution encountered an error.

ID should do the same, cause we walk up the chain of devices on the
physical device and can match for the name of every device there with
the ID key.

Fix from: Hannes Reinecke <hare@suse.de>
namedev_parse is a bit overzealous when in comes to handling backspaces;
it always eats up backspaces regardless of anything beyond that. This
means it is impossible to enter '\t' in a rule. Quite a bit of fun when
you're trying to write regexps.
|

Here we move all possible options into a own key to make it possible
to have options-only rules.
The options on the NAME key are removed from the man page and will
be removed from a future version of udev.
For ignore rules, OPTIONS="ignore" should be used.
The rule:
SUBSYSTEM="block", SYSFS{removable}="1", OPTIONS="all_partitions"
will create all partitions for a block device which is known to have
removable media (a check for cdrom drives would be needed too).
