systemd System and Session Manager 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. Contributions from: Dan Horák, Kay Sievers, Lennart Poettering, Michal Schmidt 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.
