systemd System and Service Manager
-CHANGES WITH:
- * systemd-logingctl and systemd-journalctl have been renamed
- to logingctl and journalctl to match systemctl.
+CHANGES WITH 198:
+
+ * Configuration of unit files may now be extended via drop-in
+ files without having to edit/override the unit files
+ themselves. More specifically, if the administrator wants to
+ change one value for a service file foobar.service he can
+ now do so by dropping in a configuration snippet into
+ /etc/systemd/system/foobar.service.d/*.conf. The unit logic
+ will load all these snippets and apply them on top of the
+ main unit configuration file, possibly extending or
+ overriding its settings. Using these drop-in snippets is
+ generally nicer than the two earlier options for changing
+ unit files locally: copying the files from
+ /usr/lib/systemd/system/ to /etc/systemd/system/ and editing
+ them there; or creating a new file in /etc/systemd/system/
+ that incorporates the original one via ".include". Drop-in
+ snippets into these .d/ directories can be placed in any
+ directory systemd looks for units in, and the usual
+ overriding semantics between /usr/lib, /etc and /run apply
+ for them too.
+
+ * Most unit file settings which take lists of items can now be
+ reset by assigning the empty string to them. For example,
+ normally, settings such as Environment=FOO=BAR append a new
+ environment variable assignment to the environment block,
+ each time they are used. By assigning Environment= the empty
+ string the environment block can be reset to empty. This is
+ particularly useful with the .d/*.conf drop-in snippets
+ mentioned above, since this adds the ability to reset list
+ settings from vendor unit files via these drop-ins.
+
+ * systemctl gained a new "list-dependencies" command for
+ listing the dependencies of a unit recursively.
+
+ * Inhibitors are now honored and listed by "systemctl
+ suspend", "systemctl poweroff" (and similar) too, not only
+ GNOME. These commands will also list active sessions by
+ other users.
+
+ * Resource limits (as exposed by the various control group
+ controllers) can now be controlled dynamically at runtime
+ for all units. More specifically, you can now use a command
+ like "systemctl set-cgroup-attr foobar.service cpu.shares
+ 2000" to alter the CPU shares a specific service gets. These
+ settings are stored persistently on disk, and thus allow the
+ administrator to easily adjust the resource usage of
+ services with a few simple commands. This dynamic resource
+ management logic is also available to other programs via the
+ bus. Almost any kernel cgroup attribute and controller is
+ supported.
+
+ * systemd-vconsole-setup will now copy all font settings to
+ all allocated VTs, where it previously applied them only to
+ the foreground VT.
+
+ * libsystemd-login gained the new sd_session_get_tty() API
+ call.
+
+ * This release drops support for a few legacy or
+ distribution-specific LSB facility names when parsing init
+ scripts: $x-display-manager, $mail-transfer-agent,
+ $mail-transport-agent, $mail-transfer-agent, $smtp,
+ $null. Also, the mail-transfer-agent.target unit backing
+ this has been removed. Distributions which want to retain
+ compatibility with this should carry the burden for
+ supporting this themselves and patch support for these back
+ in, if they really need to. Also, the facilities $syslog and
+ $local_fs are now ignored, since systemd does not support
+ early-boot LSB init scripts anymore, and these facilities
+ are implied anyway for normal services. syslog.target has
+ also been removed.
+
+ * There are new bus calls on PID1's Manager object for
+ cancelling jobs, and removing snapshot units. Previously,
+ both calls were only available on the Job and Snapshot
+ objects themselves.
+
+ * systemd-journal-gatewayd gained SSL support.
+
+ * The various "environment" files, such as /etc/locale.conf
+ now support continuation lines with a backslash ("\") as
+ last character in the line, similar in style (but different)
+ to how this is supported in shells.
+
+ * For normal user processes the _SYSTEMD_USER_UNIT= field is
+ now implicitly appended to every log entry logged. systemctl
+ has been updated to filter by this field when operating on a
+ user systemd instance.
+
+ * nspawn will now implicitly add the CAP_AUDIT_WRITE and
+ CAP_AUDIT_CONTROL capabilities to the capabilities set for
+ the container. This makes it easier to boot unmodified
+ Fedora systems in a container, which however still requires
+ audit=0 to be passed on the kernel command line. Auditing in
+ kernel and userspace is unfortunately still too broken in
+ context of containers, hence we recommend compiling it out
+ of the kernel or using audit=0. Hopefully this will be fixed
+ one day for good in the kernel.
+
+ * nspawn gained the new --bind= and --bind-ro= parameters to
+ bind mount specific directories from the host into the
+ container.
+
+ * nspawn will now mount its own devpts file system instance
+ into the container, in order not to leak pty devices from
+ the host into the container.
+
+ * systemd will now read the firmware boot time performance
+ information from the EFI variables, if the used boot loader
+ supports this, and takes it into account for boot performance
+ analysis via "systemd-analyze". This is currently supported
+ only in conjunction with Gummiboot, but could be supported
+ by other boot loaders too. For details see:
+
+ http://www.freedesktop.org/wiki/Software/systemd/BootLoaderInterface
+
+ * A new generator has been added that automatically mounts the
+ EFI System Partition (ESP) to /boot, if that directory
+ exists, is empty, and no other file system has been
+ configured to be mounted there.
+
+ * logind will now send out PrepareForSleep(false) out
+ unconditionally, after coming back from suspend. This may be
+ used by applications as asynchronous notification for
+ system resume events.
+
+ * "systemctl unlock-sessions" has been added, that allows
+ unlocking the screens of all user sessions at once, similar
+ how "systemctl lock-sessions" already locked all users
+ sessions. This is backed by a new D-Bus call UnlockSessions().
+
+ * "loginctl seat-status" will now show the master device of a
+ seat. (i.e. the device of a seat that needs to be around for
+ the seat to be considered available, usually the graphics
+ card).
+
+ * tmpfiles gained a new "X" line type, that allows
+ configuration of files and directories (with wildcards) that
+ shall be excluded from automatic cleanup ("aging").
+
+ * udev default rules set the device node permissions now only
+ at "add" events, and do not change them any longer with a
+ later "change" event.
+
+ * The log messages for lid events and power/sleep keypresses
+ now carry a message ID.
+
+ * We now have a substantially larger unit test suite, but this
+ continues to be work in progress.
+
+ * udevadm hwdb gained a new --root= parameter to change the
+ root directory to operate relative to.
+
+ * logind will now issue a background sync() request to the kernel
+ early at shutdown, so that dirty buffers are flushed to disk early
+ instead of at the last moment, in order to optimize shutdown
+ times a little.
+
+ * A new bootctl tool has been added that is an interface for
+ certain boot loader operations. This is currently a preview
+ and is likely to be extended into a small mechanism daemon
+ like timedated, localed, hostnamed, and can be used by
+ graphical UIs to enumerate available boot options, and
+ request boot into firmware operations.
+
+ * systemd-bootchart has been relicensed to LGPLv2.1+ to match
+ the rest of the package. It also has been updated to work
+ correctly in initrds.
+
+ * Policykit previously has been runtime optional, and is now
+ also compile time optional via a configure switch.
+
+ * systemd-analyze has been reimplemented in C. Also "systemctl
+ dot" has moved into systemd-analyze.
+
+ * "systemctl status" with no further parameters will now print
+ the status of all active or failed units.
+
+ * Operations such as "systemctl start" can now be executed
+ with a new mode "--irreversible" which may be used to queue
+ operations that cannot accidentally be reversed by a later
+ job queuing. This is by default used to make shutdown
+ requests more robust.
+
+ * The Python API of systemd now gained a new module for
+ reading journal files.
+
+ * A new tool kernel-install has been added that can install
+ kernel images according to the Boot Loader Specification:
+
+ http://www.freedesktop.org/wiki/Specifications/BootLoaderSpec
+
+ * Boot time console output has been improved to provide
+ animated boot time output for hanging jobs.
+
+ * A new tool systemd-activate has been added which can be used
+ to test socket activation with, directly from the command
+ line. This should make it much easier to test and debug
+ socket activation in daemons.
+
+ * journalctl gained a new "--reverse" (or -r) option to show
+ journal output in reverse order (i.e. newest line first).
+
+ * journalctl gained a new "--pager-end" (or -e) option to jump
+ to immediately jump to the end of the journal in the
+ pager. This is only supported in conjunction with "less".
+
+ * journalctl gained a new "--user-unit=" option, that works
+ similar to "--unit=" but filters for user units rather than
+ system units.
+
+ * A number of unit files to ease adoption of systemd in
+ initrds has been added. This moves some minimal logic from
+ the various initrd implementations into systemd proper.
+
+ * The journal files are now owned by a new group
+ "systemd-journal", which exists specifically to allow access
+ to the journal, and nothing else. Previously, we used the
+ "adm" group for that, which however possibly covers more
+ than just journal/log file access. This new group is now
+ already used by systemd-journal-gatewayd to ensure this
+ daemon gets access to the journal files and as little else
+ as possible. Note that "make install" will also set FS ACLs
+ up for /var/log/journal to give "adm" and "wheel" read
+ access to it, in addition to "systemd-journal" which owns
+ the journal files. We recommend that packaging scripts also
+ add read access to "adm" + "wheel" to /var/log/journal, and
+ all existing/future journal files. To normal users and
+ administrators little changes, however packagers need to
+ ensure to create the "systemd-journal" system group at
+ package installation time.
+
+ * The systemd-journal-gatewayd now runs as unprivileged user
+ systemd-journal-gateway:systemd-journal-gateway. Packaging
+ scripts need to create these system user/group at
+ installation time.
+
+ * timedated now exposes a new boolean property CanNTP that
+ indicates whether a local NTP service is available or not.
+
+ * systemd-detect-virt will now also detect xen PVs
+
+ * The pstore file system is now mounted by default, if it is
+ available.
+
+ * In addition to the SELinux and IMA policies we will now also
+ load SMACK policies at early boot.

+
+CHANGES WITH 197:
+
+ * Timer units now support calendar time events in addition to
+ monotonic time events. That means you can now trigger a unit
+ based on a calendar time specification such as "Thu,Fri
+ 2013-*-1,5 11:12:13" which refers to 11:12:13 of the first
+ or fifth day of any month of the year 2013, given that it is
+ a thursday or friday. This brings timer event support
+ considerably closer to cron's capabilities. For details on
+ the supported calendar time specification language see
+ systemd.time(7).
+
+ * udev now supports a number of different naming policies for
+ network interfaces for predictable names, and a combination
+ of these policies is now the default. Please see this wiki
+ document for details:
+
+ http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames
+
+ * Auke Kok's bootchart implementation has been added to the
+ systemd tree. It's an optional component that can graph the
+ boot in quite some detail. It's one of the best bootchart
+ implementations around and minimal in its code and
+ dependencies.
+
+ * nss-myhostname has been integrated into the systemd source
+ tree. nss-myhostname guarantees that the local hostname
+ always stays resolvable via NSS. It has been a weak
+ requirement of systemd-hostnamed since a long time, and
+ since its code is actually trivial we decided to just
+ include it in systemd's source tree. It can be turned off
+ with a configure switch.
+
+ * The read-ahead logic is now capable of properly detecting
+ whether a btrfs file system is on SSD or rotating media, in
+ order to optimize the read-ahead scheme. Previously, it was
+ only capable of detecting this on traditional file systems
+ such as ext4.
+
+ * In udev, additional device properties are now read from the
+ IAB in addition to the OUI database. Also, Bluetooth company
+ identities are attached to the devices as well.
+
+ * In service files %U may be used as specifier that is
+ replaced by the configured user name of the service.
+
+ * nspawn may now be invoked without a controlling TTY. This
+ makes it suitable for invocation as its own service. This
+ may be used to set up a simple containerized server system
+ using only core OS tools.
+
+ * systemd and nspawn can now accept socket file descriptors
+ when they are started for socket activation. This enables
+ implementation of socket activated nspawn
+ containers. i.e. think about autospawning an entire OS image
+ when the first SSH or HTTP connection is received. We expect
+ that similar functionality will also be added to libvirt-lxc
+ eventually.
+
+ * journalctl will now suppress ANSI color codes when
+ presenting log data.
+
+ * systemctl will no longer show control group information for
+ a unit if a the control group is empty anyway.
+
+ * logind can now automatically suspend/hibernate/shutdown the
+ system on idle.
+
+ * /etc/machine-info and hostnamed now also expose the chassis
+ type of the system. This can be used to determine whether
+ the local system is a laptop, desktop, handset or
+ tablet. This information may either be configured by the
+ user/vendor or is automatically determined from ACPI and DMI
+ information if possible.
+
+ * A number of PolicyKit actions are now bound together with
+ "imply" rules. This should simplify creating UIs because
+ many actions will now authenticate similar ones as well.
+
+ * Unit files learnt a new condition ConditionACPower= which
+ may be used to conditionalize a unit depending on whether an
+ AC power source is connected or not, of whether the system
+ is running on battery power.
+
+ * systemctl gained a new "is-failed" verb that may be used in
+ shell scripts and suchlike to check whether a specific unit
+ is in the "failed" state.
+
+ * The EnvironmentFile= setting in unit files now supports file
+ globbing, and can hence be used to easily read a number of
+ environment files at once.
+
+ * systemd will no longer detect and recognize specific
+ distributions. All distribution-specific #ifdeffery has been
+ removed, systemd is now fully generic and
+ distribution-agnostic. Effectively, not too much is lost as
+ a lot of the code is still accessible via explicit configure
+ switches. However, support for some distribution specific
+ legacy configuration file formats has been dropped. We
+ recommend distributions to simply adopt the configuration
+ files everybody else uses now and convert the old
+ configuration from packaging scripts. Most distributions
+ already did that. If that's not possible or desirable,
+ distributions are welcome to forward port the specific
+ pieces of code locally from the git history.
+
+ * When logging a message about a unit systemd will now always
+ log the unit name in the message meta data.
+
+ * localectl will now also discover system locale data that is
+ not stored in locale archives, but directly unpacked.
+
+ * logind will no longer unconditionally use framebuffer
+ devices as seat masters, i.e. as devices that are required
+ to be existing before a seat is considered preset. Instead,
+ it will now look for all devices that are tagged as
+ "seat-master" in udev. By default framebuffer devices will
+ be marked as such, but depending on local systems other
+ devices might be marked as well. This may be used to
+ integrate graphics cards using closed source drivers (such
+ as NVidia ones) more nicely into logind. Note however, that
+ we recommend using the open source NVidia drivers instead,
+ and no udev rules for the closed-source drivers will be
+ shipped from us upstream.

+
+CHANGES WITH 196:
+
+ * udev gained support for loading additional device properties
+ from an indexed database that is keyed by vendor/product IDs
+ and similar device identifiers. For the beginning this
+ "hwdb" is populated with data from the well-known PCI and
+ USB database, but also includes PNP, ACPI and OID data. In
+ the longer run this indexed database shall grow into
+ becoming the one central database for non-essential
+ userspace device metadata. Previously, data from the PCI/USB
+ database was only attached to select devices, since the
+ lookup was a relatively expensive operation due to O(n) time
+ complexity (with n being the number of entries in the
+ database). Since this is now O(1), we decided to add in this
+ data for all devices where this is available, by
+ default. Note that the indexed database needs to be rebuilt
+ when new data files are installed. To achieve this you need
+ to update your packaging scripts to invoke "udevadm hwdb
+ --update" after installation of hwdb data files. For
+ RPM-based distributions we introduced the new
+ %udev_hwdb_update macro for this purpose.
+
+ * The Journal gained support for the "Message Catalog", an
+ indexed database to link up additional information with
+ journal entries. For further details please check:
+
+ http://www.freedesktop.org/wiki/Software/systemd/catalog
+
+ The indexed message catalog database also needs to be
+ rebuilt after installation of message catalog files. Use
+ "journalctl --update-catalog" for this. For RPM-based
+ distributions we introduced the %journal_catalog_update
+ macro for this purpose.
+
+ * The Python Journal bindings gained support for the standard
+ Python logging framework.
+
+ * The Journal API gained new functions for checking whether
+ the underlying file system of a journal file is capable of
+ properly reporting file change notifications, or whether
+ applications that want to reflect journal changes "live"
+ need to recheck journal files continously in appropriate
+ time intervals.
+
+ * It is now possible to set the "age" field for tmpfiles
+ entries to 0, indicating that files matching this entry
+ shall always be removed when the directories are cleaned up.
+
+ * coredumpctl gained a new "gdb" verb which invokes gdb
+ right-away on the selected coredump.
+
+ * There's now support for "hybrid sleep" on kernels that
+ support this, in addition to "suspend" and "hibernate". Use
+ "systemctl hybrid-sleep" to make use of this.
+
+ * logind's HandleSuspendKey= setting (and related settings)
+ now gained support for a new "lock" setting to simply
+ request the screen lock on all local sessions, instead of
+ actually executing a suspend or hibernation.
+
+ * systemd will now mount the EFI variables file system by
+ default.
+
+ * Socket units now gained support for configuration of the
+ SMACK security label.
+
+ * timedatectl will now output the time of the last and next
+ daylight saving change.
+
+ * We dropped support for various legacy and distro-specific
+ concepts, such as insserv, early-boot SysV services
+ (i.e. those for non-standard runlevels such as 'b' or 'S')
+ or ArchLinux /etc/rc.conf support. We recommend the
+ distributions who still need support this to either continue
+ to maintain the necessary patches downstream, or find a
+ different solution. (Talk to us if you have questions!)
+
+ * Various systemd components will now bypass PolicyKit checks
+ for root and otherwise handle properly if PolicyKit is not
+ found to be around. This should fix most issues for
+ PolicyKit-less systems. Quite frankly this should have been
+ this way since day one. It is absolutely our intention to
+ make systemd work fine on PolicyKit-less systems, and we
+ consider it a bug if something doesn't work as it should if
+ PolicyKit is not around.
+
+ * For embedded systems it is now possible to build udev and
+ systemd without blkid and/or kmod support.
+
+ * "systemctl switch-root" is now capable of switching root
+ more than once. I.e. in addition to transitions from the
+ initrd to the host OS it is now possible to transition to
+ further OS images from the host. This is useful to implement
+ offline updating tools.
+
+ * Various other additions have been made to the RPM macros
+ shipped with systemd. Use %udev_rules_update() after
+ installing new udev rules files. %_udevhwdbdir,
+ %_udevrulesdir, %_journalcatalogdir, %_tmpfilesdir,
+ %_sysctldir are now available which resolve to the right
+ directories for packages to place various data files in.
+
+ * journalctl gained the new --full switch (in addition to
+ --all, to disable ellipsation for long messages.

+
+CHANGES WITH 195:
+
+ * journalctl gained new --since= and --until= switches to
+ filter by time. 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!

+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.

+
+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
+

+
+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.

+
+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.

+
+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).

+
+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.

+
+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.

+
+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

+
+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

+
+ * MaxLevelStore=, MaxLevelSyslog=, MaxLevelKMsg=,
+ MaxLevelConsole= can now be specified in
+ journald.conf. These options allow reducing the amount of

+
+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.
+
