It also now supports nice filtering for - units via --unit=/-u. - - * Type=oneshot services may use ExecReload= and do the - right thing. - - * The journal daemon now supports time-based rotation and - vacuuming, in addition to the usual disk-space based - rotation. - - * The journal will now index the available field values for - each field name. This enables clients to show pretty drop - downs of available match values when filtering. The bash - completion of journalctl has been updated - accordingly. journalctl gained a new switch -F to list all - values a certain field takes in the journal database. - - * More service events are now written as structured messages - to the journal, and made recognizable via message IDs. - - * The timedated, localed and hostnamed mini-services which - previously only provided support for changing time, locale - and hostname settings from graphical DEs such as GNOME now - also have a minimal (but very useful) text-based client - utility each. This is probably the nicest way to changing - these settings from the command line now, especially since - it lists available options and is fully integrated with bash - completion. - - * There's now a new tool "systemd-coredumpctl" to list and - extract coredumps from the journal. - - * We now install a README each in /var/log/ and - /etc/rc.d/init.d explaining where the system logs and init - scripts went. This hopefully should help folks who go to - that dirs and look into the otherwise now empty void and - scratch their heads. - - * When user-services are invoked (by systemd --user) the - $MANAGERPID env var is set to the PID of systemd. - - * SIGRTMIN+24 when sent to a --user instance will now result - in immediate termination of systemd. - - * gatewayd received numerous feature additions such as a - "follow" mode, for live syncing and filtering. - - * browse.html now allows filtering and showing detailed - information on specific entries. Keyboard navigation and - mouse screen support has been added. - - * gatewayd/journalctl now supports HTML5/JSON - Server-Sent-Events as output. - - * The SysV init script compatibility logic will now - heuristically determine whether a script supports the - "reload" verb, and only then make this available as - "systemctl reload". - - * "systemctl status --follow" has been removed, use "journalctl - -u" instead. - - * journald.conf's RuntimeMinSize=, PersistentMinSize= settings - have been removed since they are hardly useful to be - configured. - - * And I'd like to take the opportunity to specifically mention - Zbigniew for his great contributions. Zbigniew, you rock! - - Contributions from: Andrew Eikum, Christian Hesse, Colin - Guthrie, Daniel J Walsh, Dave Reisner, Eelco Dolstra, Ferenc - Wágner, Kay Sievers, Lennart Poettering, Lukas Nykryn, Mantas - Mikulėnas, Martin Mikkelsen, Martin Pitt, Michael Olbrich, - Michael Stapelberg, Michal Schmidt, Sebastian Ott, Thomas - Bächler, Umut Tezduyar, Will Woods, Wulf C. Krueger, Zbigniew - Jędrzejewski-Szmek, Сковорода Никита Андреевич - -CHANGES WITH 194: - - * If /etc/vconsole.conf is non-existent or empty we will no - longer load any console font or key map at boot by - default. Instead the kernel defaults will be left - intact. This is definitely the right thing to do, as no - configuration should mean no configuration, and hard-coding - font names that are different on all archs is probably a bad - idea. Also, the kernel default key map and font should be - good enough for most cases anyway, and mostly identical to - the userspace fonts/key maps we previously overloaded them - with. If distributions want to continue to default to a - non-kernel font or key map they should ship a default - /etc/vconsole.conf with the appropriate contents. - - Contributions from: Colin Walters, Daniel J Walsh, Dave - Reisner, Kay Sievers, Lennart Poettering, Lukas Nykryn, Tollef - Fog Heen, Tom Gundersen, Zbigniew Jędrzejewski-Szmek - -CHANGES WITH 193: - - * journalctl gained a new --cursor= switch to show entries - starting from the specified location in the journal. - - * We now enforce a size limit on journal entry fields exported - with "-o json" in journalctl. Fields larger than 4K will be - assigned null. This can be turned off with --all. - - * An (optional) journal gateway daemon is now available as - "systemd-journal-gatewayd.service". This service provides - access to the journal via HTTP and JSON. This functionality - will be used to implement live log synchronization in both - pull and push modes, but has various other users too, such - as easy log access for debugging of embedded devices. Right - now it is already useful to retrieve the journal via HTTP: - - # systemctl start systemd-journal-gatewayd.service - # wget http://localhost:19531/entries - - This will download the journal contents in a - /var/log/messages compatible format. The same as JSON: - - # curl -H"Accept: application/json" http://localhost:19531/entries - - This service is also accessible via a web browser where a - single static HTML5 app is served that uses the JSON logic - to enable the user to do some basic browsing of the - journal. This will be extended later on. Here's an example - screenshot of this app in its current state: - - http://0pointer.de/public/journal-gatewayd - - Contributions from: Kay Sievers, Lennart Poettering, Robert - Milasan, Tom Gundersen - -CHANGES WITH 192: - - * The bash completion logic is now available for journalctl - too. - - * We don't mount the "cpuset" controller anymore together with - "cpu" and "cpuacct", as "cpuset" groups generally cannot be - started if no parameters are assigned to it. "cpuset" hence - broke code that assumed it it could create "cpu" groups and - just start them. - - * journalctl -f will now subscribe to terminal size changes, - and line break accordingly. - - Contributions from: Dave Reisner, Kay Sievers, Lennart - Poettering, Lukas Nykrynm, Mirco Tischler, Václav Pavlín - -CHANGES WITH 191: - - * nspawn will now create a symlink /etc/localtime in the - container environment, copying the host's timezone - setting. Previously this has been done via a bind mount, but - since symlinks cannot be bind mounted this has now been - changed to create/update the appropriate symlink. - - * journalctl -n's line number argument is now optional, and - will default to 10 if omitted. - - * journald will now log the maximum size the journal files may - take up on disk. This is particularly useful if the default - built-in logic of determining this parameter from the file - system size is used. Use "systemctl status - systemd-journald.service" to see this information. - - * The multi-seat X wrapper tool has been stripped down. As X - is now capable of enumerating graphics devices via udev in a - seat-aware way the wrapper is not strictly necessary - anymore. A stripped down temporary stop-gap is still shipped - until the upstream display managers have been updated to - fully support the new X logic. Expect this wrapper to be - removed entirely in one of the next releases. - - * HandleSleepKey= in logind.conf has been split up into - HandleSuspendKey= and HandleHibernateKey=. The old setting - is not available anymore. X11 and the kernel are - distuingishing between these keys and we should too. This - also means the inhibition lock for these keys has been split - into two. - - Contributions from: Dave Airlie, Eelco Dolstra, Lennart - Poettering, Lukas Nykryn, Václav Pavlín - -CHANGES WITH 190: - - * Whenever a unit changes state we'll now log this to the - journal and show along the unit's own log output in - "systemctl status". - - * ConditionPathIsMountPoint= can now properly detect bind - mount points too. (Previously, a bind mount of one file - system to another place in the same file system could not be - detected as mount, since they shared struct stat's st_dev - field.) - - * We will now mount the cgroup controllers cpu, cpuacct, - cpuset and the controllers net_cls, net_prio together by - default. - - * nspawn containers will now have a virtualized boot - ID. (i.e. /proc/sys/kernel/random/boot_id is now mounted - over with a randomized ID at container initialization). This - has the effect of making "journalctl -b" do the right thing - in a container. - - * The JSON output journal serialization has been updated not - to generate "endless" list objects anymore, but rather one - JSON object per line. This is more in line how most JSON - parsers expect JSON objects. The new output mode - "json-pretty" has been added to provide similar output, but - neatly aligned for readability by humans. - - * We dropped all explicit sync() invocations in the shutdown - code. The kernel does this implicitly anyway in the kernel - reboot() syscall. halt(8)'s -n option is now a compatibility - no-op. - - * We now support virtualized reboot() in containers, as - supported by newer kernels. We will fall back to exit() if - CAP_SYS_REBOOT is not available to the container. Also, - nspawn makes use of this now and will actually reboot the - container if the containerized OS asks for that. - - * journalctl will only show local log output by default - now. Use --merge (-m) to show remote log output, too. - - * libsystemd-journal gained the new sd_journal_get_usage() - call to determine the current disk usage of all journal - files. This is exposed in the new "journalctl --disk-usage" - command. - - * journald gained a new configuration setting SplitMode= in - journald.conf which may be used to control how user journals - are split off. See journald.conf(5) for details. - - * A new condition type ConditionFileNotEmpty= has been added. - - * tmpfiles' "w" lines now support file globbing, to write - multiple files at once. - - * We added Python bindings for the journal submission - APIs. More Python APIs for a number of selected APIs will - likely follow. Note that we intend to add native bindings - only for the Python language, as we consider it common - enough to deserve bindings shipped within systemd. There are - various projects outside of systemd that provide bindings - for languages such as PHP or Lua. - - * Many conditions will now resolve specifiers such as %i. In - addition, PathChanged= and related directives of .path units - now support specifiers as well. - - * There's now a new RPM macro definition for the system preset - dir: %_presetdir. - - * journald will now warn if it can't foward a message to the - syslog daemon because it's socket is full. - - * timedated will no longer write or process /etc/timezone, - except on Debian. As we do not support late mounted /usr - anymore /etc/localtime always being a symlink is now safe, - and hence the information in /etc/timezone is not necessary - anymore. - - * logind will now always reserve one VT for a text getty (VT6 - by default). Previously if more than 6 X sessions where - started they took up all the VTs with auto-spawned gettys, - so that no text gettys were available anymore. - - * udev will now automatically inform the btrfs kernel logic - about btrfs RAID components showing up. This should make - simple hotplug based btrfs RAID assembly work. - - * PID 1 will now increase its RLIMIT_NOFILE to 64K by default - (but not for its children which will stay at the kernel - default). This should allow setups with a lot more listening - sockets. - - * systemd will now always pass the configured timezone to the - kernel at boot. timedated will do the same when the timezone - is changed. - - * logind's inhibition logic has been updated. By default, - logind will now handle the lid switch, the power and sleep - keys all the time, even in graphical sessions. If DEs want - to handle these events on their own they should take the new - handle-power-key, handle-sleep-key and handle-lid-switch - inhibitors during their runtime. A simple way to achiveve - that is to invoke the DE wrapped in an invocation of: - - systemd-inhibit --what=handle-power-key:handle-sleep-key:handle-lid-switch ... - - * Access to unit operations is now checked via SELinux taking - the unit file label and client process label into account. - - * systemd will now notify the administrator in the journal - when he over-mounts a non-empty directory. - - * There are new specifiers that are resolved in unit files, - for the host name (%H), the machine ID (%m) and the boot ID - (%b). - - Contributions from: Allin Cottrell, Auke Kok, Brandon Philips, - Colin Guthrie, Colin Walters, Daniel J Walsh, Dave Reisner, - Eelco Dolstra, Jan Engelhardt, Kay Sievers, Lennart - Poettering, Lucas De Marchi, Lukas Nykryn, Mantas Mikulėnas, - Martin Pitt, Matthias Clasen, Michael Olbrich, Pierre Schmitz, - Shawn Landden, Thomas Hindoe Paaboel Andersen, Tom Gundersen, - Václav Pavlín, Yin Kangkai, Zbigniew Jędrzejewski-Szmek - -CHANGES WITH 189: - - * Support for reading structured kernel messages from - /dev/kmsg has now been added and is enabled by default. - - * Support for reading kernel messages from /proc/kmsg has now - been removed. If you want kernel messages in the journal - make sure to run a recent kernel (>= 3.5) that supports - reading structured messages from /dev/kmsg (see - above). /proc/kmsg is now exclusive property of classic - syslog daemons again. - - * The libudev API gained the new - udev_device_new_from_device_id() call. - - * The logic for file system namespace (ReadOnlyDirectory=, - ReadWriteDirectoy=, PrivateTmp=) has been reworked not to - require pivot_root() anymore. This means fewer temporary - directories are created below /tmp for this feature. - - * nspawn containers will now see and receive all submounts - made on the host OS below the root file system of the - container. - - * Forward Secure Sealing is now supported for Journal files, - which provide cryptographical sealing of journal files so - that attackers cannot alter log history anymore without this - being detectable. Lennart will soon post a blog story about - this explaining it in more detail. - - * There are two new service settings RestartPreventExitStatus= - and SuccessExitStatus= which allow configuration of exit - status (exit code or signal) which will be excepted from the - restart logic, resp. consider successful. - - * journalctl gained the new --verify switch that can be used - to check the integrity of the structure of journal files and - (if Forward Secure Sealing is enabled) the contents of - journal files. - - * nspawn containers will now be run with /dev/stdin, /dev/fd/ - and similar symlinks pre-created. This makes running shells - as container init process a lot more fun. - - * The fstab support can now handle PARTUUID= and PARTLABEL= - entries. - - * A new ConditionHost= condition has been added to match - against the hostname (with globs) and machine ID. This is - useful for clusters where a single OS image is used to - provision a large number of hosts which shall run slightly - different sets of services. - - * Services which hit the restart limit will now be placed in a - failure state. - - Contributions from: Bertram Poettering, Dave Reisner, Huang - Hang, Kay Sievers, Lennart Poettering, Lukas Nykryn, Martin - Pitt, Simon Peeters, Zbigniew Jędrzejewski-Szmek - -CHANGES WITH 188: - - * When running in --user mode systemd will now become a - subreaper (PR_SET_CHILD_SUBREAPER). This should make the ps - tree a lot more organized. - - * A new PartOf= unit dependency type has been introduced that - may be used to group services in a natural way. - - * "systemctl enable" may now be used to enable instances of - services. - - * journalctl now prints error log levels in red, and - warning/notice log levels in bright white. It also supports - filtering by log level now. - - * cgtop gained a new -n switch (similar to top), to configure - the maximum number of iterations to run for. It also gained - -b, to run in batch mode (accepting no input). - - * The suffix ".service" may now be ommited on most systemctl - command lines involving service unit names. - - * There's a new bus call in logind to lock all sessions, as - well as a loginctl verb for it "lock-sessions". - - * libsystemd-logind.so gained a new call sd_journal_perror() - that works similar to libc perror() but logs to the journal - and encodes structured information about the error number. - - * /etc/crypttab entries now understand the new keyfile-size= - option. - - * shutdown(8) now can send a (configurable) wall message when - a shutdown is cancelled. - - * The mount propagation mode for the root file system will now - default to "shared", which is useful to make containers work - nicely out-of-the-box so that they receive new mounts from - the host. This can be undone locally by running "mount - --make-rprivate /" if needed. - - * The prefdm.service file has been removed. Distributions - should maintain this unit downstream if they intend to keep - it around. However, we recommend writing normal unit files - for display managers instead. - - * Since systemd is a crucial part of the OS we will now - default to a number of compiler switches that improve - security (hardening) such as read-only relocations, stack - protection, and suchlike. - - * The TimeoutSec= setting for services is now split into - TimeoutStartSec= and TimeoutStopSec= to allow configuration - of individual time outs for the start and the stop phase of - the service. - - Contributions from: Artur Zaprzala, Arvydas Sidorenko, Auke - Kok, Bryan Kadzban, Dave Reisner, David Strauss, Harald Hoyer, - Jim Meyering, Kay Sievers, Lennart Poettering, Mantas - Mikulėnas, Martin Pitt, Michal Schmidt, Michal Sekletar, Peter - Alfredsen, Shawn Landden, Simon Peeters, Terence Honles, Tom - Gundersen, Zbigniew Jędrzejewski-Szmek - -CHANGES WITH 187: - - * The journal and id128 C APIs are now fully documented as man - pages. - - * Extra safety checks have been added when transitioning from - the initial RAM disk to the main system to avoid accidental - data loss. - - * /etc/crypttab entries now understand the new keyfile-offset= - option. - - * systemctl -t can now be used to filter by unit load state. - - * The journal C API gained the new sd_journal_wait() call to - make writing synchronous journal clients easier. - - * journalctl gained the new -D switch to show journals from a - specific directory. - - * journalctl now displays a special marker between log - messages of two different boots. - - * The journal is now explicitly flushed to /var via a service - systemd-journal-flush.service, rather than implicitly simply - by seeing /var/log/journal to be writable. - - * journalctl (and the journal C APIs) can now match for much - more complex expressions, with alternatives and - disjunctions. - - * When transitioning from the initial RAM disk to the main - system we will now kill all processes in a killing spree to - ensure no processes stay around by accident. - - * Three new specifiers may be used in unit files: %u, %h, %s - resolve to the user name, user home directory resp. user - shell. This is useful for running systemd user instances. - - * We now automatically rotate journal files if their data - object hash table gets a fill level > 75%. We also size the - hash table based on the configured maximum file size. This - together should lower hash collisions drastically and thus - speed things up a bit. - - * journalctl gained the new "--header" switch to introspect - header data of journal files. - - * A new setting SystemCallFilters= has been added to services - which may be used to apply blacklists or whitelists to - system calls. This is based on SECCOMP Mode 2 of Linux 3.5. - - * nspawn gained a new --link-journal= switch (and quicker: -j) - to link the container journal with the host. This makes it - very easy to centralize log viewing on the host for all - guests while still keeping the journal files separated. - - * Many bugfixes and optimizations - - Contributions from: Auke Kok, Eelco Dolstra, Harald Hoyer, Kay - Sievers, Lennart Poettering, Malte Starostik, Paul Menzel, Rex - Tsai, Shawn Landden, Tom Gundersen, Ville Skyttä, Zbigniew - Jędrzejewski-Szmek - -CHANGES WITH 186: - - * Several tools now understand kernel command line arguments, - which are only read when run in an initial RAM disk. They - usually follow closely their normal counterparts, but are - prefixed with rd. - - * There's a new tool to analyze the readahead files that are - automatically generated at boot. Use: - - /usr/lib/systemd/systemd-readahead analyze /.readahead - - * We now provide an early debug shell on tty9 if this enabled. Use: - - systemctl enable debug-shell.service - - * All plymouth related units have been moved into the Plymouth - package. Please make sure to upgrade your Plymouth version - as well. - - * systemd-tmpfiles now supports getting passed the basename of - a configuration file only, in which case it will look for it - in all appropriate directories automatically. - - * udevadm info now takes a /dev or /sys path as argument, and - does the right thing. Example: - - udevadm info /dev/sda - udevadm info /sys/class/block/sda - - * systemctl now prints a warning if a unit is stopped but a - unit that might trigger it continues to run. Example: a - service is stopped but the socket that activates it is left - running. - - * "systemctl status" will now mention if the log output was - shortened due to rotation since a service has been started. - - * The journal API now exposes functions to determine the - "cutoff" times due to rotation. - - * journald now understands SIGUSR1 and SIGUSR2 for triggering - immediately flushing of runtime logs to /var if possible, - resp. for triggering immediate rotation of the journal - files. - - * It is now considered an error if a service is attempted to - be stopped that is not loaded. - - * XDG_RUNTIME_DIR now uses numeric UIDs instead of usernames. - - * systemd-analyze now supports Python 3 - - * tmpfiles now supports cleaning up directories via aging - where the first level dirs are always kept around but - directories beneath it automatically aged. This is enabled - by prefixing the age field with '~'. - - * Seat objects now expose CanGraphical, CanTTY properties - which is required to deal with very fast bootups where the - display manager might be running before the graphics drivers - completed initialization. - - * Seat objects now expose a State property. - - * We now include RPM macros for service enabling/disabling - based on the preset logic. We recommend RPM based - distributions to make use of these macros if possible. This - makes it simpler to reuse RPM spec files across - distributions. - - * We now make sure that the collected systemd unit name is - always valid when services log to the journal via - STDOUT/STDERR. - - * There's a new man page kernel-command-line(7) detailing all - command line options we understand. - - * The fstab generator may now be disabled at boot by passing - fstab=0 on the kernel command line. - - * A new kernel command line option modules-load= is now understood - to load a specific kernel module statically, early at boot. - - * Unit names specified on the systemctl command line are now - automatically escaped as needed. Also, if file system or - device paths are specified they are automatically turned - into the appropriate mount or device unit names. Example: - - systemctl status /home - systemctl status /dev/sda - - * The SysVConsole= configuration option has been removed from - system.conf parsing. - - * The SysV search path is no longer exported on the D-Bus - Manager object. - - * The Names= option is been removed from unit file parsing. - - * There's a new man page bootup(7) detailing the boot process. - - * Every unit and every generator we ship with systemd now - comes with full documentation. The self-explanatory boot is - complete. - - * A couple of services gained "systemd-" prefixes in their - name if they wrap systemd code, rather than only external - code. Among them fsck@.service which is now - systemd-fsck@.service. - - * The HaveWatchdog property has been removed from the D-Bus - Manager object. - - * systemd.confirm_spawn= on the kernel command line should now - work sensibly. - - * There's a new man page crypttab(5) which details all options - we actually understand. - - * systemd-nspawn gained a new --capability= switch to pass - additional capabilities to the container. - - * timedated will now read known NTP implementation unit names - from /usr/lib/systemd/ntp-units.d/*.list, - systemd-timedated-ntp.target has been removed. - - * journalctl gained a new switch "-b" that lists log data of - the current boot only. - - * The notify socket is in the abstract namespace again, in - order to support daemons which chroot() at start-up. - - * There is a new Storage= configuration option for journald - which allows configuration of where log data should go. This - also provides a way to disable journal logging entirely, so - that data collected is only forwarded to the console, the - kernel log buffer or another syslog implementation. - - * Many bugfixes and optimizations - - Contributions from: Auke Kok, Colin Guthrie, Dave Reisner, - David Strauss, Eelco Dolstra, Kay Sievers, Lennart Poettering, - Lukas Nykryn, Michal Schmidt, Michal Sekletar, Paul Menzel, - Shawn Landden, Tom Gundersen - -CHANGES WITH 185: - - * "systemctl help <unit>" now shows the man page if one is - available. - - * Several new man pages have been added. - - * MaxLevelStore=, MaxLevelSyslog=, MaxLevelKMsg=, - MaxLevelConsole= can now be specified in - journald.conf. These options allow reducing the amount of - data stored on disk or forwarded by the log level. - - * TimerSlackNSec= can now be specified in system.conf for - PID1. This allows system-wide power savings. - - Contributions from: Dave Reisner, Kay Sievers, Lauri Kasanen, - Lennart Poettering, Malte Starostik, Marc-Antoine Perennou, - Matthias Clasen - -CHANGES WITH 184: - - * logind is now capable of (optionally) handling power and - sleep keys as well as the lid switch. - - * journalctl now understands the syntax "journalctl - /usr/bin/avahi-daemon" to get all log output of a specific - daemon. - - * CapabilityBoundingSet= in system.conf now also influences - the capability bound set of usermode helpers of the kernel. - - Contributions from: Daniel Drake, Daniel J. Walsh, Gert - Michael Kulyk, Harald Hoyer, Jean Delvare, Kay Sievers, - Lennart Poettering, Matthew Garrett, Matthias Clasen, Paul - Menzel, Shawn Landden, Tero Roponen, Tom Gundersen - -CHANGES WITH 183: - - * Note that we skipped 139 releases here in order to set the - new version to something that is greater than both udev's - and systemd's most recent version number. - - * udev: all udev sources are merged into the systemd source tree now. - All future udev development will happen in the systemd tree. It - is still fully supported to use the udev daemon and tools without - systemd running, like in initramfs or other init systems. Building - udev though, will require the *build* of the systemd tree, but - udev can be properly *run* without systemd. - - * udev: /lib/udev/devices/ are not read anymore; systemd-tmpfiles - should be used to create dead device nodes as workarounds for broken - subsystems. - - * udev: RUN+="socket:..." and udev_monitor_new_from_socket() is - no longer supported. udev_monitor_new_from_netlink() needs to be - used to subscribe to events. - - * udev: when udevd is started by systemd, processes which are left - behind by forking them off of udev rules, are unconditionally cleaned - up and killed now after the event handling has finished. Services or - daemons must be started as systemd services. Services can be - pulled-in by udev to get started, but they can no longer be directly - forked by udev rules. - - * udev: the daemon binary is called systemd-udevd now and installed - in /usr/lib/systemd/. Standalone builds or non-systemd systems need - to adapt to that, create symlink, or rename the binary after building - it. - - * libudev no longer provides these symbols: - udev_monitor_from_socket() - udev_queue_get_failed_list_entry() - udev_get_{dev,sys,run}_path() - The versions number was bumped and symbol versioning introduced. - - * systemd-loginctl and systemd-journalctl have been renamed - to loginctl and journalctl to match systemctl. - - * The config files: /etc/systemd/systemd-logind.conf and - /etc/systemd/systemd-journald.conf have been renamed to - logind.conf and journald.conf. Package updates should rename - the files to the new names on upgrade. - - * For almost all files the license is now LGPL2.1+, changed - from the previous GPL2.0+. Exceptions are some minor stuff - of udev (which will be changed to LGPL2.1 eventually, too), - and the MIT licensed sd-daemon.[ch] library that is suitable - to be used as drop-in files. - - * systemd and logind now handle system sleep states, in - particular suspending and hibernating. - - * logind now implements a sleep/shutdown/idle inhibiting logic - suitable for a variety of uses. Soonishly Lennart will blog - about this in more detail. - - * var-run.mount and var-lock.mount are no longer provided - (which prevously bind mounted these directories to their new - places). Distributions which have not converted these - directories to symlinks should consider stealing these files - from git history and add them downstream. - - * We introduced the Documentation= field for units and added - this to all our shipped units. This is useful to make it - easier to explore the boot and the purpose of the various - units. - - * All smaller setup units (such as - systemd-vconsole-setup.service) now detect properly if they - are run in a container and are skipped when - appropriate. This guarantees an entirely noise-free boot in - Linux container environments such as systemd-nspawn. - - * A framework for implementing offline system updates is now - integrated, for details see: - http://freedesktop.org/wiki/Software/systemd/SystemUpdates - - * A new service type Type=idle is available now which helps us - avoiding ugly interleaving of getty output and boot status - messages. - - * There's now a system-wide CapabilityBoundingSet= option to - globally reduce the set of capabilities for the - system. This is useful to drop CAP_SYS_MKNOD, CAP_SYS_RAWIO, - CAP_NET_RAW, CAP_SYS_MODULE, CAP_SYS_TIME, CAP_SYS_PTRACE or - even CAP_NET_ADMIN system-wide for secure systems. - - * There are now system-wide DefaultLimitXXX= options to - globally change the defaults of the various resource limits - for all units started by PID 1. - - * Harald Hoyer's systemd test suite has been integrated into - systemd which allows easy testing of systemd builds in qemu - and nspawn. (This is really awesome! Ask us for details!) - - * The fstab parser is now implemented as generator, not inside - of PID 1 anymore. - - * systemctl will now warn you if .mount units generated from - /etc/fstab are out of date due to changes in fstab that - haven't been read by systemd yet. - - * systemd is now suitable for usage in initrds. Dracut has - already been updated to make use of this. With this in place - initrds get a slight bit faster but primarily are much - easier to introspect and debug since "systemctl status" in - the host system can be used to introspect initrd services, - and the journal from the initrd is kept around too. - - * systemd-delta has been added, a tool to explore differences - between user/admin configuration and vendor defaults. - - * PrivateTmp= now affects both /tmp and /var/tmp. - - * Boot time status messages are now much prettier and feature - proper english language. Booting up systemd has never been - so sexy. - - * Read-ahead pack files now include the inode number of all - files to pre-cache. When the inode changes the pre-caching - is not attempted. This should be nicer to deal with updated - packages which might result in changes of read-ahead - patterns. - - * We now temporaritly lower the kernel's read_ahead_kb variable - when collecting read-ahead data to ensure the kernel's - built-in read-ahead does not add noise to our measurements - of necessary blocks to pre-cache. - - * There's now RequiresMountsFor= to add automatic dependencies - for all mounts necessary for a specific file system path. - - * MountAuto= and SwapAuto= have been removed from - system.conf. Mounting file systems at boot has to take place - in systemd now. - - * nspawn now learned a new switch --uuid= to set the machine - ID on the command line. - - * nspawn now learned the -b switch to automatically search - for an init system. - - * vt102 is now the default TERM for serial TTYs, upgraded from - vt100. - - * systemd-logind now works on VT-less systems. - - * The build tree has been reorganized. The individual - components now have directories of their own. - - * A new condition type ConditionPathIsReadWrite= is now available. - - * nspawn learned the new -C switch to create cgroups for the - container in other hierarchies. - - * We now have support for hardware watchdogs, configurable in - system.conf. - - * The scheduled shutdown logic now has a public API. - - * We now mount /tmp as tmpfs by default, but this can be - masked and /etc/fstab can override it. - - * Since udisks doesn't make use of /media anymore we are not - mounting a tmpfs on it anymore. - - * journalctl gained a new --local switch to only interleave - locally generated journal files. - - * We can now load the IMA policy at boot automatically. - - * The GTK tools have been split off into a systemd-ui. - - Contributions from: Andreas Schwab, Auke Kok, Ayan George, - Colin Guthrie, Daniel Mack, Dave Reisner, David Ward, Elan - Ruusamäe, Frederic Crozat, Gergely Nagy, Guillermo Vidal, - Hannes Reinecke, Harald Hoyer, Javier Jardón, Kay Sievers, - Lennart Poettering, Lucas De Marchi, Léo Gillot-Lamure, - Marc-Antoine Perennou, Martin Pitt, Matthew Monaco, Maxim - A. Mikityanskiy, Michael Biebl, Michael Olbrich, Michal - Schmidt, Nis Martensen, Patrick McCarty, Roberto Sassu, Shawn - Landden, Sjoerd Simons, Sven Anders, Tollef Fog Heen, Tom - Gundersen - -CHANGES WITH 44: - - * This is mostly a bugfix release - - * Support optional initialization of the machine ID from the - KVM or container configured UUID. - - * Support immediate reboots with "systemctl reboot -ff" - - * Show /etc/os-release data in systemd-analyze output - - * Many bugfixes for the journal, including endianess fixes and - ensuring that disk space enforcement works - - * sd-login.h is C++ comptaible again - - * Extend the /etc/os-release format on request of the Debian - folks - - * We now refuse non-UTF8 strings used in various configuration - and unit files. This is done to ensure we don't pass invalid - data over D-Bus or expose it elsewhere. - - * Register Mimo USB Screens as suitable for automatic seat - configuration - - * Read SELinux client context from journal clients in a race - free fashion - - * Reorder configuration file lookup order. /etc now always - overrides /run in order to allow the administrator to always - and unconditionally override vendor supplied or - automatically generated data. - - * The various user visible bits of the journal now have man - pages. We still lack man pages for the journal API calls - however. - - * We now ship all man pages in HTML format again in the - tarball. - - Contributions from: Dave Reisner, Dirk Eibach, Frederic - Crozat, Harald Hoyer, Kay Sievers, Lennart Poettering, Marti - Raudsepp, Michal Schmidt, Shawn Landden, Tero Roponen, Thierry - Reding - -CHANGES WITH 43: - - * This is mostly a bugfix release - - * systems lacking /etc/os-release are no longer supported. - - * Various functionality updates to libsystemd-login.so - - * Track class of PAM logins to distuingish greeters from - normal user logins. - - Contributions from: Kay Sievers, Lennart Poettering, Michael - Biebl - -CHANGES WITH 42: - - * This is an important bugfix release for v41. - - * Building man pages is now optional which should be useful - for those building systemd from git but unwilling to install - xsltproc. - - * Watchdog support for supervising services is now usable. In - a future release support for hardware watchdogs - (i.e. /dev/watchdog) will be added building on this. - - * Service start rate limiting is now configurable and can be - turned off per service. When a start rate limit is hit a - reboot can automatically be triggered. - - * New CanReboot(), CanPowerOff() bus calls in systemd-logind. - - Contributions from: Benjamin Franzke, Bill Nottingham, - Frederic Crozat, Lennart Poettering, Michael Olbrich, Michal - Schmidt, Michał Górny, Piotr Drąg - -CHANGES WITH 41: - - * The systemd binary is installed /usr/lib/systemd/systemd now; - An existing /sbin/init symlink needs to be adapted with the - package update. - - * The code that loads kernel modules has been ported to invoke - libkmod directly, instead of modprobe. This means we do not - support systems with module-init-tools anymore. - - * Watchdog support is now already useful, but still not - complete. - - * A new kernel command line option systemd.setenv= is - understood to set system wide environment variables - dynamically at boot. - - * We now limit the set of capabilities of systemd-journald. - - * We now set SIGPIPE to ignore by default, since it only is - useful in shell pipelines, and has little use in general - code. This can be disabled with IgnoreSIPIPE=no in unit - files. - - Contributions from: Benjamin Franzke, Kay Sievers, Lennart - Poettering, Michael Olbrich, Michal Schmidt, Tom Gundersen, - William Douglas - -CHANGES WITH 40: - - * This is mostly a bugfix release - - * We now expose the reason why a service failed in the - "Result" D-Bus property. - - * Rudimentary service watchdog support (will be completed over - the next few releases.) - - * When systemd forks off in order execute some service we will - now immediately changes its argv[0] to reflect which process - it will execute. This is useful to minimize the time window - with a generic argv[0], which makes bootcharts more useful - - Contributions from: Alvaro Soliverez, Chris Paulson-Ellis, Kay - Sievers, Lennart Poettering, Michael Olbrich, Michal Schmidt, - Mike Kazantsev, Ray Strode - -CHANGES WITH 39: - - * This is mostly a test release, but incorporates many - bugfixes. - - * New systemd-cgtop tool to show control groups by their - resource usage. - - * Linking against libacl for ACLs is optional again. If - disabled, support tracking device access for active logins - goes becomes unavailable, and so does access to the user - journals by the respective users. - - * If a group "adm" exists, journal files are automatically - owned by them, thus allow members of this group full access - to the system journal as well as all user journals. - - * The journal now stores the SELinux context of the logging - client for all entries. - - * Add C++ inclusion guards to all public headers - - * New output mode "cat" in the journal to print only text - messages, without any meta data like date or time. - - * Include tiny X server wrapper as a temporary stop-gap to - teach XOrg udev display enumeration. This is used by display - managers such as gdm, and will go away as soon as XOrg - learned native udev hotplugging for display devices. - - * Add new systemd-cat tool for executing arbitrary programs - with STDERR/STDOUT connected to the journal. Can also act as - BSD logger replacement, and does so by default. - - * Optionally store all locally generated coredumps in the - journal along with meta data. - - * systemd-tmpfiles learnt four new commands: n, L, c, b, for - writing short strings to files (for usage for /sys), and for - creating symlinks, character and block device nodes. - - * New unit file option ControlGroupPersistent= to make cgroups - persistent, following the mechanisms outlined in - http://www.freedesktop.org/wiki/Software/systemd/PaxControlGroups - - * Support multiple local RTCs in a sane way - - * No longer monopolize IO when replaying readahead data on - rotating disks, since we might starve non-file-system IO to - death, since fanotify() will not see accesses done by blkid, - or fsck. - - * Don't show kernel threads in systemd-cgls anymore, unless - requested with new -k switch. - - Contributions from: Dan Horák, Kay Sievers, Lennart - Poettering, Michal Schmidt - -CHANGES WITH 38: - - * This is mostly a test release, but incorporates many - bugfixes. - - * The git repository moved to: - git://anongit.freedesktop.org/systemd/systemd - ssh://git.freedesktop.org/git/systemd/systemd - - * First release with the journal - http://0pointer.de/blog/projects/the-journal.html - - * The journal replaces both systemd-kmsg-syslogd and - systemd-stdout-bridge. - - * New sd_pid_get_unit() API call in libsystemd-logind - - * Many systemadm clean-ups - - * Introduce remote-fs-pre.target which is ordered before all - remote mounts and may be used to start services before all - remote mounts. - - * Added Mageia support - - * Add bash completion for systemd-loginctl - - * Actively monitor PID file creation for daemons which exit in - the parent process before having finished writing the PID - file in the daemon process. Daemons which do this need to be - fixed (i.e. PID file creation must have finished before the - parent exits), but we now react a bit more gracefully to them. - - * Add colourful boot output, mimicking the well-known output - of existing distributions. - - * New option PassCredentials= for socket units, for - compatibility with a recent kernel ABI breakage. - - * /etc/rc.local is now hooked in via a generator binary, and - thus will no longer act as synchronization point during - boot. - - * systemctl list-unit-files now supports --root=. - - * systemd-tmpfiles now understands two new commands: z, Z for - relabelling files according to the SELinux database. This is - useful to apply SELinux labels to specific files in /sys, - among other things. - - * Output of SysV services is now forwarded to both the console - and the journal by default, not only just the console. - - * New man pages for all APIs from libsystemd-login. - - * The build tree got reorganized and a the build system is a - lot more modular allowing embedded setups to specifically - select the components of systemd they are interested in. - - * Support for Linux systems lacking the kernel VT subsystem is - restored. - - * configure's --with-rootdir= got renamed to - --with-rootprefix= to follow the naming used by udev and - kmod - - * Unless specified otherwise we'll now install to /usr instead - of /usr/local by default. - - * Processes with '@' in argv[0][0] are now excluded from the - final shut-down killing spree, following the logic explained - in: - http://www.freedesktop.org/wiki/Software/systemd/RootStorageDaemons - - * All processes remaining in a service cgroup when we enter - the START or START_PRE states are now killed with - SIGKILL. That means it is no longer possible to spawn - background processes from ExecStart= lines (which was never - supported anyway, and bad style). - - * New PropagateReloadTo=/PropagateReloadFrom= options to bind - reloading of units together. - - Contributions from: Bill Nottingham, Daniel J.
