systemd System and Service Manager

CHANGES WITH 43:
        * This is mostly a bugfix release

        * systems lacking /etc/os-release  are no longer supported.

        * Various functionality updates to libsystemd-login.so

        * Track class of PAM logins to distuingish greeters from
          normal user logins.

        Biebl

CHANGES WITH 42:
        * This is an important bugfix release for v41.

        * Building man pages is now optional which should be useful
          for those building systemd from git but unwilling to install
          xsltproc.

        * Watchdog support for supervising services is now usable. In
          a future release support for hardware watchdogs
          (i.e. /dev/watchdog) will be added building on this.

        * Service start rate limiting is now configurable and can be
          turned off per service. When a start rate limit is hit a
          reboot can automatically be triggered.

        * New CanReboot(), CanPowerOff() bus calls in systemd-logind.

CHANGES WITH 41:
        * The systemd binary is installed /usr/lib/systemd/systemd now;
          An existing /sbin/init symlink needs to be adapted with the
          package update.

        * The code that loads kernel modules has been ported to invoke
          libkmod directly, instead of modprobe. This means we do not
          support systems with module-init-tools anymore.

        * Watchdog support is now already useful, but still not
          complete.

        * A new kernel command line option systemd.setenv= is
          understood to set system wide environment variables
          dynamically at boot.

	* We now limit the set of capabilities of systemd-journald.

        * We now set SIGPIPE to ignore by default, since it only is
          useful in shell pipelines, and has little use in general
          code. This can be disabled with IgnoreSIPIPE=no in unit
          files.

CHANGES WITH 40:
        * This is mostly a bugfix release

        * We now expose the reason why a service failed in the
          "Result" D-Bus property.

        * Rudimentary service watchdog support (will be completed over
          the next few releases.)

        * When systemd forks off in order execute some service we will
          now immediately changes its argv[0] to reflect which process
          it will execute. This is useful to minimize the time window
          with a generic argv[0], which makes bootcharts more useful

CHANGES WITH 39:
        * This is mostly a test release, but incorporates many
          bugfixes.

        * New systemd-cgtop tool to show control groups by their
          resource usage.

        * Linking against libacl for ACLs is optional again. If
          disabled, support tracking device access for active logins
          goes becomes unavailable, and so does access to the user
          journals by the respective users.

        * If a group "adm" exists, journal files are automatically
          owned by them, thus allow members of this group full access
          to the system journal as well as all user journals.

        * The journal now stores the SELinux context of the logging
          client for all entries.

        * Add C++ inclusion guards to all public headers

        * New output mode "cat" in the journal to print only text
          messages, without any meta data like date or time.

        * Include tiny X server wrapper as a temporary stop-gap to
          teach XOrg udev display enumeration. This is used by display
          managers such as gdm, and will go away as soon as XOrg
          learned native udev hotplugging for display devices.

        * Add new systemd-cat tool for executing arbitrary programs
          with STDERR/STDOUT connected to the journal. Can also act as
          BSD logger replacement, and does so by default.

        * Optionally store all locally generated coredumps in the
          journal along with meta data.

        * systemd-tmpfiles learnt four new commands: n, L, c, b, for
          writing short strings to files (for usage for /sys), and for
          creating symlinks, character and block device nodes.

        * New unit file option ControlGroupPersistent= to make cgroups
          persistent, following the mechanisms outlined in
          http://www.freedesktop.org/wiki/Software/systemd/PaxControlGroups

        * Support multiple local RTCs in a sane way

        * No longer monopolize IO when replaying readahead data on
          rotating disks, since we might starve non-file-system IO to
          death, since fanotify() will not see accesses done by blkid,
          or fsck.

        * Don't show kernel threads in systemd-cgls anymore, unless
          requested with new -k switch.

CHANGES WITH 38:
        * This is mostly a test release, but incorporates many
          bugfixes.

        * The git repository moved to:
          git://anongit.freedesktop.org/systemd/systemd
          ssh://git.freedesktop.org/git/systemd/systemd

        * First release with the journal
          http://0pointer.de/blog/projects/the-journal.html

        * The journal replaces both systemd-kmsg-syslogd and
          systemd-stdout-bridge.

        * New sd_pid_get_unit() API call in libsystemd-logind

        * Many systemadm clean-ups

        * Introduce remote-fs-pre.target which is ordered before all
          remote mounts and may be used to start services before all
          remote mounts.

        * Added Mageia support

        * Add bash completion for systemd-loginctl

        * Actively monitor PID file creation for daemons which exit in
          the parent process before having finished writing the PID
          file in the daemon process. Daemons which do this need to be
          fixed (i.e. PID file creation must have finished before the
          parent exits), but we now react a bit more gracefully to them.

        * Add colourful boot output, mimicking the well-known output
          of existing distributions.

        * New option PassCredentials= for socket units, for
          compatibility with a recent kernel ABI breakage.

        * /etc/rc.local is now hooked in via a generator binary, and
          thus will no longer act as synchronization point during
          boot.

        * systemctl list-unit-files now supports --root=.

        * systemd-tmpfiles now understands two new commands: z, Z for
          relabelling files according to the SELinux database. This is
          useful to apply SELinux labels to specific files in /sys,
          among other things.

        * Output of SysV services is now forwarded to both the console
          and the journal by default, not only just the console.

        * New man pages for all APIs from libsystemd-login.

        * The build tree got reorganized and a the build system is a
          lot more modular allowing embedded setups to specifically
          select the components of systemd they are interested in.

        * Support for Linux systems lacking the kernel VT subsystem is
          restored.

        * configure's --with-rootdir= got renamed to
          --with-rootprefix= to follow the naming used by udev and
          kmod

        * Unless specified otherwise we'll now install to /usr instead
          of /usr/local by default.

        * Processes with '@' in argv[0][0] are now excluded from the
          final shut-down killing spree, following the logic explained
          in:
          http://www.freedesktop.org/wiki/Software/systemd/RootStorageDaemons

        * All processes remaining in a service cgroup when we enter
          the START or START_PRE states are now killed with
          SIGKILL. That means it is no longer possible to spawn
          background processes from ExecStart= lines (which was never
          supported anyway, and bad style).

        * New PropagateReloadTo=/PropagateReloadFrom= options to bind
          reloading of units together.
