systemd System and Service Manager
+CHANGES WITH 207:
+
+ * The Restart= option for services now understands a new
+ on-watchdog setting, which will restart the service
+ automatically if the service stops sending out watchdog keep
+ alive messages (as configured with WatchdogSec=).
+
+ * The getty generator (which is responsible for bringing up a
+ getty on configured serial consoles) will no longer only
+ start a getty on the primary kernel console but on all
+ others, too. This makes the order in which console= is
+ specified on the kernel command line less important.
+
+ * libsystemd-logind gained a new sd_session_get_vt() call to
+ retrieve the VT number of a session.
+
+ * If the option "tries=0" is set for an entry of /etc/crypttab
+ its passphrase is queried indefinitely instead of any
+ maximum number of tries.
+
+ * If a service with a configure PID file terminates its PID
+ file will now be removed automatically if it still exists
+ afterwards. This should put an end to stale PID files.
+
+ * systemd-run will now also take relative binary path names
+ for execution and no longer insists on absolute paths.
+
+ * InaccessibleDirectories= and ReadOnlyDirectories= now take
+ paths that are optionally prefixed with "-" to indicate that
+ it should not be considered a failure if they don't exist.
+
+ * journalctl -o (and similar commands) now understands a new
+ output mode "short-precise", it is similar to "short" but
+ shows timestamps with usec accuracy.
+
+ * The option "discard" (as known from Debian) is now
+ synonymous to "allow-discards" in /etc/crypttab. In fact,
+ "discard" is preferred now (since it is easier to remember
+ and type).
+
+ * Some licensing clean-ups were made, so that more code is now
+ LGPL-2.1 licensed than before.
+
+ * A minimal tool to save/restore the display backlight
+ brightness across reboots has been added. It will store the
+ backlight setting as late as possible at shutdown, and
+ restore it as early as possible during reboot.
+
+ * A logic to automatically discover and enable home and swap
+ partitions on GPT disks has been added. With this in place
+ /etc/fstab becomes optional for many setups as systemd can
+ discover certain partitions located on the root disk
+ automatically. Home partitions are recognized under their
+ GPT type ID 933ac7e12eb44f13b8440e14e2aef915. Swap
+ partitions are recognized under their GPT type ID
+ 0657fd6da4ab43c484e50933c84b4f4f.
+
+ * systemd will no longer pass any environment from the kernel
+ or initrd to system services. If you want to set an
+ environment for all services, do so via the kernel command
+ line systemd.setenv= assignment.
+
+ * The systemd-sysctl tool no longer natively reads the file
+ /etc/sysctl.conf. If desired, the file should be symlinked
+ from /etc/sysctl.d/99-sysctl.conf. Apart from providing
+ legacy support by a symlink rather than built-in code, it
+ also makes the otherwise hidden order of application of the
+ different files visible. (Note that this partly reverts to a
+ pre-198 application order of sysctl knobs!)
+
+ * The "systemctl set-log-level" and "systemctl dump" commands
+ have been moved to systemd-analyze.
+
+ * systemd-run learned the new --remain-after-exit switch,
+ which causes the scope unit not to be cleaned up
+ automatically after the process terminated.
+
+ * tmpfiles learned a new --exclude-prefix= switch to exclude
+ certain paths from operation.
+
+ * journald will now automatically flush all messages to disk
+ as soon as a message of the log priorities CRIT, ALERT or
+ EMERG is received.

+
+CHANGES WITH 206:
+
+ * The documentation has been updated to cover the various new
+ concepts introduced with 205.
+
+ * Unit files now understand the new %v specifier which
+ resolves to the kernel version string as returned by "uname
+ -r".
+
+ * systemctl now supports filtering the unit list output by
+ load state, active state and sub state, using the new
+ --state= parameter.
+
+ * "systemctl status" will now show the results of the
+ condition checks (like ConditionPathExists= and similar) of
+ the last start attempts of the unit. They are also logged to
+ the journal.
+
+ * "journalctl -b" may now be used to look for boot output of a
+ specific boot. Try "journalctl -b -1" for the previous boot,
+ but the syntax is substantially more powerful.
+
+ * "journalctl --show-cursor" has been added which prints the
+ cursor string the last shown log line. This may then be used
+ with the new "journalctl --after-cursor=" switch to continue
+ browsing logs from that point on.
+
+ * "journalctl --force" may now be used to force regeneration
+ of an FSS key.
+
+ * Creation of "dead" device nodes has been moved from udev
+ into kmod and tmpfiles. Previously, udev would read the kmod
+ databases to pre-generate dead device nodes based on meta
+ information contained in kernel modules, so that these would
+ be auto-loaded on access rather then at boot. As this
+ doesn't really have much to do with the exposing actual
+ kernel devices to userspace this has always been slightly
+ alien in the udev codebase. Following the new scheme kmod
+ will now generate a runtime snippet for tmpfiles from the
+ module meta information and it now is tmpfiles' job to the
+ create the nodes. This also allows overriding access and
+ other parameters for the nodes using the usual tmpfiles
+ facilities. As side effect this allows us to remove the
+ CAP_SYS_MKNOD capability bit from udevd entirely.
+
+ * logind's device ACLs may now be applied to these "dead"
+ devices nodes too, thus finally allowing managed access to
+ devices such as /dev/snd/sequencer whithout loading the
+ backing module right-away.
+
+ * A new RPM macro has been added that may be used to apply
+ tmpfiles configuration during package installation.
+
+ * systemd-detect-virt and ConditionVirtualization= now can
+ detect User-Mode-Linux machines (UML).
+
+ * journald will now implicitly log the effective capabilities
+ set of processes in the message metadata.
+
+ * systemd-cryptsetup has gained support for TrueCrypt volumes.
+
+ * The initrd interface has been simplified (more specifically,
+ support for passing performance data via environment
+ variables and fsck results via files in /run has been
+ removed). These features were non-essential, and are
+ nowadays available in a much nicer way by having systemd in
+ the initrd serialize its state and have the hosts systemd
+ deserialize it again.
+
+ * The udev "keymap" data files and tools to apply keyboard
+ specific mappings of scan to key codes, and force-release
+ scan code lists have been entirely replaced by a udev
+ "keyboard" builtin and a hwdb data file.
+
+ * systemd will now honour the kernel's "quiet" command line
+ argument also during late shutdown, resulting in a
+ completely silent shutdown when used.
+
+ * There's now an option to control the SO_REUSEPORT socket
+ option in .socket units.
+
+ * Instance units will now automatically get a per-template
+ subslice of system.slice unless something else is explicitly
+ configured. For example, instances of sshd@.service will now
+ implicitly be placed in system-sshd.slice rather than
+ system.slice as before.
+
+ * Test coverage support may now be enabled at build time.

+
+ -- Berlin, 2013-07-23
+
+CHANGES WITH 205:
+
+ * Two new unit types have been introduced:
+
+ Scope units are very similar to service units, however, are
+ created out of pre-existing processes -- instead of PID 1
+ forking off the processes. By using scope units it is
+ possible for system services and applications to group their
+ own child processes (worker processes) in a powerful way
+ which then maybe used to organize them, or kill them
+ together, or apply resource limits on them.
+
+ Slice units may be used to partition system resources in an
+ hierarchial fashion and then assign other units to them. By
+ default there are now three slices: system.slice (for all
+ system services), user.slice (for all user sessions),
+ machine.slice (for VMs and containers).
+
+ Slices and scopes have been introduced primarily in
+ context of the work to move cgroup handling to a
+ single-writer scheme, where only PID 1
+ creates/removes/manages cgroups.
+
+ * There's a new concept of "transient" units. In contrast to
+ normal units these units are created via an API at runtime,
+ not from configuration from disk. More specifically this
+ means it is now possible to run arbitrary programs as
+ independent services, with all execution parameters passed
+ in via bus APIs rather than read from disk. Transient units
+ make systemd substantially more dynamic then it ever was,
+ and useful as a general batch manager.
+
+ * logind has been updated to make use of scope and slice units
+ for managing user sessions. As a user logs in he will get
+ his own private slice unit, to which all sessions are added
+ as scope units. We also added support for automatically
+ adding an instance of user@.service for the user into the
+ slice. Effectively logind will no longer create cgroup
+ hierarchies on its own now, it will defer entirely to PID 1
+ for this by means of scope, service and slice units. Since
+ user sessions this way become entities managed by PID 1
+ the output of "systemctl" is now a lot more comprehensive.
+
+ * A new mini-daemon "systemd-machined" has been added which
+ may be used by virtualization managers to register local
+ VMs/containers. nspawn has been updated accordingly, and
+ libvirt will be updated shortly. machined will collect a bit
+ of meta information about the VMs/containers, and assign
+ them their own scope unit (see above). The collected
+ meta-data is then made available via the "machinectl" tool,
+ and exposed in "ps" and similar tools. machined/machinectl
+ is compile-time optional.
+
+ * As discussed earlier, the low-level cgroup configuration
+ options ControlGroup=, ControlGroupModify=,
+ ControlGroupPersistent=, ControlGroupAttribute= have been
+ removed. Please use high-level attribute settings instead as
+ well as slice units.
+
+ * A new bus call SetUnitProperties() has been added to alter
+ various runtime parameters of a unit. This is primarily
+ useful to alter cgroup parameters dynamically in a nice way,
+ but will be extended later on to make more properties
+ modifiable at runtime. systemctl gained a new set-properties
+ command that wraps this call.
+
+ * A new tool "systemd-run" has been added which can be used to
+ run arbitrary command lines as transient services or scopes,
+ while configuring a number of settings via the command
+ line. This tool is currently very basic, however already
+ very useful. We plan to extend this tool to even allow
+ queuing of execution jobs with time triggers from the
+ command line, similar in fashion to "at".
+
+ * nspawn will now inform the user explicitly that kernels with
+ audit enabled break containers, and suggest the user to turn
+ off audit.
+
+ * Support for detecting the IMA and AppArmor security
+ frameworks with ConditionSecurity= has been added.
+
+ * journalctl gained a new "-k" switch for showing only kernel
+ messages, mimicking dmesg output; in addition to "--user"
+ and "--system" switches for showing only user's own logs
+ and system logs.
+
+ * systemd-delta can now show information about drop-in
+ snippets extending unit files.
+
+ * libsystemd-bus has been substantially updated but is still
+ not available as public API.
+
+ * systemd will now look for the "debug" argument on the kernel
+ command line and enable debug logging, similar to
+ "systemd.log_level=debug" already did before.
+
+ * "systemctl set-default", "systemctl get-default" has been
+ added to configure the default.target symlink, which
+ controls what to boot into by default.
+
+ * "systemctl set-log-level" has been added as a convenient
+ way to raise and lower systemd logging threshold.
+
+ * "systemd-analyze plot" will now show the time the various
+ generators needed for execution, as well as information
+ about the unit file loading.
+
+ * libsystemd-journal gained a new sd_journal_open_files() call
+ for opening specific journal files. journactl also gained a
+ new switch to expose this new functionality. Previously we
+ only supported opening all files from a directory, or all
+ files from the system, as opening individual files only is
+ racy due to journal file rotation.
+
+ * systemd gained the new DefaultEnvironment= setting in
+ /etc/systemd/system.conf to set environment variables for
+ all services.
+
+ * If a privileged process logs a journal message with the
+ OBJECT_PID= field set, then journald will automatically
+ augment this with additional OBJECT_UID=, OBJECT_GID=,
+ OBJECT_COMM=, OBJECT_EXE=, ... fields. This is useful if
+ system services want to log events about specific client
+ processes. journactl/systemctl has been updated to make use
+ of this information if all log messages regarding a specific
+ unit is requested.

+
+CHANGES WITH 204:
+
+ * The Python bindings gained some minimal support for the APIs
+ exposed by libsystemd-logind.
+
+ * ConditionSecurity= gained support for detecting SMACK. Since
+ this condition already supports SELinux and AppArmor we only
+ miss IMA for this. Patches welcome!

+
+CHANGES WITH 203:
+
+ * systemd-nspawn will now create /etc/resolv.conf if
+ necessary, before bind-mounting the host's file onto it.
+
+ * systemd-nspawn will now store meta information about a
+ container on the container's cgroup as extended attribute
+ fields, including the root directory.
+
+ * The cgroup hierarchy has been reworked in many ways. All
+ objects any of the components systemd creates in the cgroup
+ tree are now suffixed. More specifically, user sessions are
+ now placed in cgroups suffixed with ".session", users in
+ cgroups suffixed with ".user", and nspawn containers in
+ cgroups suffixed with ".nspawn". Furthermore, all cgroup
+ names are now escaped in a simple scheme to avoid collision
+ of userspace object names with kernel filenames. This work
+ is preparation for making these objects relocatable in the
+ cgroup tree, in order to allow easy resource partitioning of
+ these objects without causing naming conflicts.
+
+ * systemctl list-dependencies gained the new switches
+ --plain, --reverse, --after and --before.
+
+ * systemd-inhibit now shows the process name of processes that
+ have taken an inhibitor lock.
+
+ * nss-myhostname will now also resolve "localhost"
+ implicitly. This makes /etc/hosts an optional file and
+ nicely handles that on IPv6 ::1 maps to both "localhost" and
+ the local hostname.
+
+ * libsystemd-logind.so gained a new call
+ sd_get_machine_names() to enumerate running containers and
+ VMs (currently only supported by very new libvirt and
+ nspawn). sd_login_monitor can now be used to watch
+ VMs/containers coming and going.
+
+ * .include is not allowed recursively anymore, and only in
+ unit files. Usually it is better to use drop-in snippets in
+ .d/*.conf anyway, as introduced with systemd 198.
+
+ * systemd-analyze gained a new "critical-chain" command that
+ determines the slowest chain of units run during system
+ boot-up. It is very useful for tracking down where
+ optimizing boot time is the most beneficial.
+
+ * systemd will no longer allow manipulating service paths in
+ the name=systemd:/system cgroup tree using ControlGroup= in
+ units. (But is still fine with it in all other dirs.)
+
+ * There's a new systemd-nspawn@.service service file that may
+ be used to easily run nspawn containers as system
+ services. With the container's root directory in
+ /var/lib/container/foobar it is now sufficient to run
+ "systemctl start systemd-nspawn@foobar.service" to boot it.
+
+ * systemd-cgls gained a new parameter "--machine" to list only
+ the processes within a certain container.
+
+ * ConditionSecurity= now can check for "apparmor". We still
+ are lacking checks for SMACK and IMA for this condition
+ check though. Patches welcome!
+
+ * A new configuration file /etc/systemd/sleep.conf has been
+ added that may be used to configure which kernel operation
+ systemd is supposed to execute when "suspend", "hibernate"
+ or "hybrid-sleep" is requested. This makes the new kernel
+ "freeze" state accessible to the user.
+
+ * ENV{SYSTEMD_WANTS} in udev rules will now implicitly escape
+ the passed argument if applicable.

+
+CHANGES WITH 202:
+
+ * The output of 'systemctl list-jobs' got some polishing. The
+ '--type=' argument may now be passed more than once. A new
+ command 'systemctl list-sockets' has been added which shows
+ a list of kernel sockets systemd is listening on with the
+ socket units they belong to, plus the units these socket
+ units activate.
+
+ * The experimental libsystemd-bus library got substantial
+ updates to work in conjunction with the (also experimental)
+ kdbus kernel project. It works well enough to exchange
+ messages with some sophistication. Note that kdbus is not
+ ready yet, and the library is mostly an elaborate test case
+ for now, and not installable.
+
+ * systemd gained a new unit 'systemd-static-nodes.service'
+ that generates static device nodes earlier during boot, and
+ can run in conjunction with udev.
+
+ * libsystemd-login gained a new call sd_pid_get_user_unit()
+ to retrieve the user systemd unit a process is running
+ in. This is useful for systems where systemd is used as
+ session manager.
+
+ * systemd-nspawn now places all containers in the new /machine
+ top-level cgroup directory in the name=systemd
+ hierarchy. libvirt will soon do the same, so that we get a
+ uniform separation of /system, /user and /machine for system
+ services, user processes and containers/virtual
+ machines. This new cgroup hierarchy is also useful to stick
+ stable names to specific container instances, which can be
+ recognized later this way (this name may be controlled
+ via systemd-nspawn's new -M switch). libsystemd-login also
+ gained a new call sd_pid_get_machine_name() to retrieve the
+ name of the container/VM a specific process belongs to.
+
+ * bootchart can now store its data in the journal.
+
+ * libsystemd-journal gained a new call
+ sd_journal_add_conjunction() for AND expressions to the
+ matching logic. This can be used to express more complex
+ logical expressions.
+
+ * journactl can now take multiple --unit= and --user-unit=
+ switches.
+
+ * The cryptsetup logic now understands the "luks.key=" kernel
+ command line switch for specifying a file to read the
+ decryption key from. Also, if a configured key file is not
+ found the tool will now automatically fall back to prompting
+ the user.
+
+ * Python systemd.journal module was updated to wrap recently
+ added functions from libsystemd-journal. The interface was
+ changed to bring the low level interface in s.j._Reader
+ closer to the C API, and the high level interface in
+ s.j.Reader was updated to wrap and convert all data about
+ an entry.

+
+CHANGES WITH 201:
+
+ * journalctl --update-catalog now understands a new --root=
+ option to operate on catalogs found in a different root
+ directory.
+
+ * During shutdown after systemd has terminated all running
+ services a final killing loop kills all remaining left-over
+ processes. We will now print the name of these processes
+ when we send SIGKILL to them, since this usually indicates a
+ problem.
+
+ * If /etc/crypttab refers to password files stored on
+ configured mount points automatic dependencies will now be
+ generated to ensure the specific mount is established first
+ before the key file is attempted to be read.
+
+ * 'systemctl status' will now show information about the
+ network sockets a socket unit is listening on.
+
+ * 'systemctl status' will also shown information about any
+ drop-in configuration file for units. (Drop-In configuration
+ files in this context are files such as
+ /etc/systemd/systemd/foobar.service.d/*.conf)
+
+ * systemd-cgtop now optionally shows summed up CPU times of
+ cgroups. Press '%' while running cgtop to switch between
+ percentage and absolute mode. This is useful to determine
+ which cgroups use up the most CPU time over the entire
+ runtime of the system. systemd-cgtop has also been updated
+ to be 'pipeable' for processing with further shell tools.
+
+ * 'hostnamectl set-hostname' will now allow setting of FQDN
+ hostnames.
+
+ * The formatting and parsing of time span values has been
+ changed. The parser now understands fractional expressions
+ such as "5.5h". The formatter will now output fractional
+ expressions for all time spans under 1min, i.e. "5.123456s"
+ rather than "5s 123ms 456us". For time spans under 1s
+ millisecond values are shown, for those under 1ms
+ microsecond values are shown. This should greatly improve
+ all time-related output of systemd.
+
+ * libsystemd-login and libsystemd-journal gained new
+ functions for querying the poll() events mask and poll()
+ timeout value for integration into arbitrary event
+ loops.
+
+ * localectl gained the ability to list available X11 keymaps
+ (models, layouts, variants, options).
+
+ * 'systemd-analyze dot' gained the ability to filter for
+ specific units via shell-style globs, to create smaller,
+ more useful graphs. I.e. it's now possible to create simple
+ graphs of all the dependencies between only target units, or
+ of all units that Avahi has dependencies with.
