1 systemd System and Service Manager
4 * udev: sources merged into the systemd sources
6 * udev: /lib/udev/devices/ are not read anymore; tmpfiles should
7 be used to create workarounds for broken subsystems.
9 * systemd-logingctl and systemd-journalctl have been renamed
10 to logingctl and journalctl to match systemctl.
12 * The config files: /etc/systemd/systemd-logind.conf and
13 /etc/systemd/systemd-journald.conf have been renamed to
14 logind.conf and journald.conf. Package updates should rename
15 the files to the new names on upgrade.
18 * This is mostly a bugfix release
20 * Support optional initialization of the machine ID from the
21 KVM or container configured UUID.
23 * Support immediate reboots with "systemctl reboot -ff"
25 * Show /etc/os-release data in systemd-analyze output
27 * Many bugfixes for the journal, including endianess fixes and
28 ensuring that disk space enforcement works
30 * sd-login.h is C++ comptaible again
32 * Extend the /etc/os-release format on request of the Debian
35 * We now refuse non-UTF8 strings used in various configuration
36 and unit files. This is done to ensure we don't pass invalid
37 data over D-Bus or expose it elsewhere.
39 * Register Mimo USB Screens as suitable for automatic seat
42 * Read SELinux client context from journal clients in a race
45 * Reorder configuration file lookup order. /etc now always
46 overrides /run in order to allow the administrator to always
47 and unconditionally override vendor supplied or
48 automatically generated data.
50 * The various user visible bits of the journal now have man
51 pages. We still lack man pages for the journal API calls
54 * We now ship all man pages in HTML format again in the

63 * This is mostly a bugfix release
65 * systems lacking /etc/os-release are no longer supported.
67 * Various functionality updates to libsystemd-login.so
69 * Track class of PAM logins to distuingish greeters from

76 * This is an important bugfix release for v41.
78 * Building man pages is now optional which should be useful
79 for those building systemd from git but unwilling to install
82 * Watchdog support for supervising services is now usable. In
83 a future release support for hardware watchdogs
84 (i.e. /dev/watchdog) will be added building on this.
86 * Service start rate limiting is now configurable and can be
87 turned off per service. When a start rate limit is hit a
88 reboot can automatically be triggered.
90 * New CanReboot(), CanPowerOff() bus calls in systemd-logind.

97 * The systemd binary is installed /usr/lib/systemd/systemd now;
98 An existing /sbin/init symlink needs to be adapted with the
101 * The code that loads kernel modules has been ported to invoke
102 libkmod directly, instead of modprobe. This means we do not
103 support systems with module-init-tools anymore.
105 * Watchdog support is now already useful, but still not
108 * A new kernel command line option systemd.setenv= is
109 understood to set system wide environment variables
112 * We now limit the set of capabilities of systemd-journald.
114 * We now set SIGPIPE to ignore by default, since it only is
115 useful in shell pipelines, and has little use in general
116 code. This can be disabled with IgnoreSIPIPE=no in unit

124 * This is mostly a bugfix release
126 * We now expose the reason why a service failed in the
127 "Result" D-Bus property.
129 * Rudimentary service watchdog support (will be completed over
130 the next few releases.)
132 * When systemd forks off in order execute some service we will
133 now immediately changes its argv[0] to reflect which process
134 it will execute. This is useful to minimize the time window
135 with a generic argv[0], which makes bootcharts more useful

142 * This is mostly a test release, but incorporates many
145 * New systemd-cgtop tool to show control groups by their
148 * Linking against libacl for ACLs is optional again. If
149 disabled, support tracking device access for active logins
150 goes becomes unavailable, and so does access to the user
151 journals by the respective users.
153 * If a group "adm" exists, journal files are automatically
154 owned by them, thus allow members of this group full access
155 to the system journal as well as all user journals.
157 * The journal now stores the SELinux context of the logging
158 client for all entries.
160 * Add C++ inclusion guards to all public headers
162 * New output mode "cat" in the journal to print only text
163 messages, without any meta data like date or time.
165 * Include tiny X server wrapper as a temporary stop-gap to
166 teach XOrg udev display enumeration. This is used by display
167 managers such as gdm, and will go away as soon as XOrg
168 learned native udev hotplugging for display devices.
170 * Add new systemd-cat tool for executing arbitrary programs
171 with STDERR/STDOUT connected to the journal. Can also act as
172 BSD logger replacement, and does so by default.
174 * Optionally store all locally generated coredumps in the
175 journal along with meta data.
177 * systemd-tmpfiles learnt four new commands: n, L, c, b, for
178 writing short strings to files (for usage for /sys), and for
179 creating symlinks, character and block device nodes.
181 * New unit file option ControlGroupPersistent= to make cgroups
182 persistent, following the mechanisms outlined in
183 http://www.freedesktop.org/wiki/Software/systemd/PaxControlGroups
185 * Support multiple local RTCs in a sane way
187 * No longer monopolize IO when replaying readahead data on
188 rotating disks, since we might starve non-file-system IO to
189 death, since fanotify() will not see accesses done by blkid,
192 * Don't show kernel threads in systemd-cgls anymore, unless
193 requested with new -k switch.

199 * This is mostly a test release, but incorporates many
202 * The git repository moved to:
203 git://anongit.freedesktop.org/systemd/systemd
204 ssh://git.freedesktop.org/git/systemd/systemd
206 * First release with the journal
207 http://0pointer.de/blog/projects/the-journal.html
209 * The journal replaces both systemd-kmsg-syslogd and
210 systemd-stdout-bridge.
212 * New sd_pid_get_unit() API call in libsystemd-logind
214 * Many systemadm clean-ups
216 * Introduce remote-fs-pre.target which is ordered before all
217 remote mounts and may be used to start services before all
220 * Added Mageia support
222 * Add bash completion for systemd-loginctl
224 * Actively monitor PID file creation for daemons which exit in
225 the parent process before having finished writing the PID
226 file in the daemon process. Daemons which do this need to be
227 fixed (i.e. PID file creation must have finished before the
228 parent exits), but we now react a bit more gracefully to them.
230 * Add colourful boot output, mimicking the well-known output
231 of existing distributions.
233 * New option PassCredentials= for socket units, for
234 compatibility with a recent kernel ABI breakage.
236 * /etc/rc.local is now hooked in via a generator binary, and
237 thus will no longer act as synchronization point during
240 * systemctl list-unit-files now supports --root=.
242 * systemd-tmpfiles now understands two new commands: z, Z for
243 relabelling files according to the SELinux database. This is
244 useful to apply SELinux labels to specific files in /sys,
247 * Output of SysV services is now forwarded to both the console
248 and the journal by default, not only just the console.
250 * New man pages for all APIs from libsystemd-login.
252 * The build tree got reorganized and a the build system is a
253 lot more modular allowing embedded setups to specifically
254 select the components of systemd they are interested in.
256 * Support for Linux systems lacking the kernel VT subsystem is
259 * configure's --with-rootdir= got renamed to
260 --with-rootprefix= to follow the naming used by udev and
263 * Unless specified otherwise we'll now install to /usr instead
264 of /usr/local by default.
266 * Processes with '@' in argv[0][0] are now excluded from the
267 final shut-down killing spree, following the logic explained
269 http://www.freedesktop.org/wiki/Software/systemd/RootStorageDaemons
271 * All processes remaining in a service cgroup when we enter
272 the START or START_PRE states are now killed with
273 SIGKILL. That means it is no longer possible to spawn
274 background processes from ExecStart= lines (which was never
275 supported anyway, and bad style).
277 * New PropagateReloadTo=/PropagateReloadFrom= options to bind
278 reloading of units together.
