1 systemd System and Service Manager
4 * This is an important bugfix release for v41.
6 * Building man pages is now optional which should be useful
7 for those building systemd from git but unwilling to install
10 * Watchdog support for supervising services is now usable. In
11 a future release support for hardware watchdogs
12 (i.e. /dev/watchdog) will be added building on this.
14 * Service start rate limiting is now configurable and can be
15 turned off per service. When a start rate limit is hit a
16 reboot can automatically be triggered.
18 * New CanReboot(), CanPowerOff() bus calls in systemd-logind.

25 * The systemd binary is installed /usr/lib/systemd/systemd now;
26 An existing /sbin/init symlink needs to be adapted with the
29 * The code that loads kernel modules has been ported to invoke
30 libkmod directly, instead of modprobe. This means we do not
31 support systems with module-init-tools anymore.
33 * Watchdog support is now already useful, but still not
36 * A new kernel command line option systemd.setenv= is
37 understood to set system wide environment variables
40 * We now limit the set of capabilities of systemd-journald.
42 * We now set SIGPIPE to ignore by default, since it only is
43 useful in shell pipelines, and has little use in general
44 code. This can be disabled with IgnoreSIPIPE=no in unit

52 * This is mostly a bugfix release
54 * We now expose the reason why a service failed in the
55 "Result" D-Bus property.
57 * Rudimentary service watchdog support (will be completed over
58 the next few releases.)
60 * When systemd forks off in order execute some service we will
61 now immediately changes its argv[0] to reflect which process
62 it will execute. This is useful to minimize the time window
63 with a generic argv[0], which makes bootcharts more useful

70 * This is mostly a test release, but incorporates many
73 * New systemd-cgtop tool to show control groups by their
76 * Linking against libacl for ACLs is optional again. If
77 disabled, support tracking device access for active logins
78 goes becomes unavailable, and so does access to the user
79 journals by the respective users.
81 * If a group "adm" exists, journal files are automatically
82 owned by them, thus allow members of this group full access
83 to the system journal as well as all user journals.
85 * The journal now stores the SELinux context of the logging
86 client for all entries.
88 * Add C++ inclusion guards to all public headers
90 * New output mode "cat" in the journal to print only text
91 messages, without any meta data like date or time.
93 * Include tiny X server wrapper as a temporary stop-gap to
94 teach XOrg udev display enumeration. This is used by display
95 managers such as gdm, and will go away as soon as XOrg
96 learned native udev hotplugging for display devices.
98 * Add new systemd-cat tool for executing arbitrary programs
99 with STDERR/STDOUT connected to the journal. Can also act as
100 BSD logger replacement, and does so by default.
102 * Optionally store all locally generated coredumps in the
103 journal along with meta data.
105 * systemd-tmpfiles learnt four new commands: n, L, c, b, for
106 writing short strings to files (for usage for /sys), and for
107 creating symlinks, character and block device nodes.
109 * New unit file option ControlGroupPersistent= to make cgroups
110 persistent, following the mechanisms outlined in
111 http://www.freedesktop.org/wiki/Software/systemd/PaxControlGroups
113 * Support multiple local RTCs in a sane way
115 * No longer monopolize IO when replaying readahead data on
116 rotating disks, since we might starve non-file-system IO to
117 death, since fanotify() will not see accesses done by blkid,
120 * Don't show kernel threads in systemd-cgls anymore, unless
121 requested with new -k switch.

127 * This is mostly a test release, but incorporates many
130 * The git repository moved to:
131 git://anongit.freedesktop.org/systemd/systemd
132 ssh://git.freedesktop.org/git/systemd/systemd
134 * First release with the journal
135 http://0pointer.de/blog/projects/the-journal.html
137 * The journal replaces both systemd-kmsg-syslogd and
138 systemd-stdout-bridge.
140 * New sd_pid_get_unit() API call in libsystemd-logind
142 * Many systemadm clean-ups
144 * Introduce remote-fs-pre.target which is ordered before all
145 remote mounts and may be used to start services before all
148 * Added Mageia support
150 * Add bash completion for systemd-loginctl
152 * Actively monitor PID file creation for daemons which exit in
153 the parent process before having finished writing the PID
154 file in the daemon process. Daemons which do this need to be
155 fixed (i.e. PID file creation must have finished before the
156 parent exits), but we now react a bit more gracefully to them.
158 * Add colourful boot output, mimicking the well-known output
159 of existing distributions.
161 * New option PassCredentials= for socket units, for
162 compatibility with a recent kernel ABI breakage.
164 * /etc/rc.local is now hooked in via a generator binary, and
165 thus will no longer act as synchronization point during
168 * systemctl list-unit-files now supports --root=.
170 * systemd-tmpfiles now understands two new commands: z, Z for
171 relabelling files according to the SELinux database. This is
172 useful to apply SELinux labels to specific files in /sys,
175 * Output of SysV services is now forwarded to both the console
176 and the journal by default, not only just the console.
178 * New man pages for all APIs from libsystemd-login.
180 * The build tree got reorganized and a the build system is a
181 lot more modular allowing embedded setups to specifically
182 select the components of systemd they are interested in.
184 * Support for Linux systems lacking the kernel VT subsystem is
187 * configure's --with-rootdir= got renamed to
188 --with-rootprefix= to follow the naming used by udev and
191 * Unless specified otherwise we'll now install to /usr instead
192 of /usr/local by default.
194 * Processes with '@' in argv[0][0] are now excluded from the
195 final shut-down killing spree, following the logic explained
197 http://www.freedesktop.org/wiki/Software/systemd/RootStorageDaemons
199 * All processes remaining in a service cgroup when we enter
200 the START or START_PRE states are now killed with
201 SIGKILL. That means it is no longer possible to spawn
202 background processes from ExecStart= lines (which was never
203 supported anyway, and bad style).
205 * New PropagateReloadTo=/PropagateReloadFrom= options to bind
206 reloading of units together.
