systemd System and Service Manager
+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).
