systemd System and Service Manager
-CHANGES WITH 182:
- * udev: sources merged into the systemd sources
-
- * udev: /lib/udev/devices/ are not read anymore; tmpfiles should
- be used to create workarounds for broken subsystems.
-
- * systemd-logingctl and systemd-journalctl have been renamed
+CHANGES WITH 183:
+ * udev: all udev sources are merged into the systemd source tree now.
+ All future udev development will happen in the systemd tree. It
+ is still fully supported to use the udev daemon and tools without
+ systemd running, like in initramfs or other init systems. Building
+ udev though, will require the *build* of the systemd tree, but
+ udev can be properly *run* without systemd.
+
+ * udev: /lib/udev/devices/ are not read anymore; systemd-tmpfiles
+ should be used to create dead device nodes as workarounds for broken
+ subsystems.
+
+ * udev: RUN+="socket:..." and udev_monitor_new_from_socket() is
+ no longer supported. udev_monitor_new_from_netlink() needs to be
+ used to subscribe to events.
+
+ * udev: when udevd is started by systemd, processes which are left
+ behind by forking them off of udev rules, are unconditionally cleaned
+ up and killed now after the event handling has finished. Services or
+ daemons must be started as systemd services. Services can be
+ pulled-in by udev to get started, but they can no longer be directly
+ forked by udev rules.
+
+ * udev: the daemon binary is called systemd-udevd now and installed
+ in /usr/lib/systemd/. Standalone builds or non-systemd systems need
+ to adapt to that, create symlink, or rename the binary after building
+ it.
+
+ * libudev no longer provides these symbols:
+ udev_monitor_from_socket()
+ udev_queue_get_failed_list_entry()
+ udev_get_{dev,sys,run}_path()
+ The versions number was bumped and symbol versioning introduced.
+
+ * systemd-loginctl and systemd-journalctl have been renamed
to logingctl and journalctl to match systemctl.
* The config files: /etc/systemd/systemd-logind.conf and
logind.conf and journald.conf. Package updates should rename
the files to the new names on upgrade.
+ * For almost all files the license is now LGPL2.1+, changed
+ from the previous GPL2.0+. Exceptions are some minor stuff
+ of udev (which will be changed to LGPL2.1 eventually, too),
+ and the MIT licensed sd-daemon.[ch] library that is suitable
+ to be used as drop-in files.
+
+ * systemd and logind now handle system sleep states, in
+ particulary suspending and hibernating.
+
+ * logind now implements a sleep/shutdown/idle inhibiting logic
+ suitable for a variety of uses. Soonishly Lennart will blog
+ about this in more detail.
+
+ * var-run.mount and var-lock.mount are no longer provided
+ (which prevously bind mounted these directories to their new
+ places). Distributions which have not converted these
+ directories to symlinks should consider stealing these files
+ from git history and add them downstream.
+
+ * We introduced the Documentation= field for units and added
+ this to all our shipped units. This is useful to make it
+ easier to explore that boot and the purpose of the various
+ units.
+
+ * All smaller setup units (such as
+ systemd-vconsole-setup.service) now detect properly if they
+ are run in a container and are skipped when
+ appropriate. This guarantees an entirely noise-free boot in
+ Linux container environments such as systemd-nspawn.
+
+ * A framework for implementing offline system updates is now
+ integrated, for details see:
+ http://freedesktop.org/wiki/Software/systemd/SystemUpdates
+
+ * A new service type Type=idle is available now which helps us
+ avoiding ugly interleaving of getty output and boot status
+ messages.
+
+ * There's now a system-wide CapabalityBoundingSet= option to
+ globally reduce the set of capabailities for the
+ system. This is useful to drop CAP_SYS_MKNOD, CAP_SYS_RAWIO,
+ CAP_NET_RAW, CAP_SYS_MODULE, CAP_SYS_TIME, CAP_SYS_PTRACE or
+ even CAP_NET_ADMIN system-wide for secure systems.
+
+ * There are now system-wide DefaultLimitXXX= options to
+ globally change the defaults of the various resource limits
+ for all units started by PID 1.
+
+ * Harald Hoyer's systemd test suite has been integrated into
+ systemd which allows easy testing of systemd builds in qemu
+ and nspawn. (This is really awesome! Ask us for details!)
+
+ * The fstab parser is now implemented as generator not inside
+ of PID 1.
+
+ * systemctl will now warn you if .mount units generated from
+ /etc/fstab are out of date due to changes in fstab that
+ haven't been read by systemd yet.
+
+ * systemd is now suitable for usage in initrds. Dracut has
+ already been updated to make use of this. With this in place
+ initrds get a slight bit faster but primarily are much
+ easier to introspect and debug since "systemctl status" in
+ the host system can be used to introspect initrd services,
+ and the journal from the initrd is kept around too.
+
+ * systemd-delta has been added, a tool to explore differences
+ between user/admin configuration and vendor defaults.
+
+ * PrivateTmp= now affects both /tmp and /var/tmp.
+
+ * Boot time status messages are now much prettier and feature
+ proper english language. Booting up systemd has never been
+ so sexy.
+
+ * Read-ahead pack files now include the inode number of all
+ files to pre-cache. When the inode changes the pre-caching
+ is not attempted. This should be nicer to deal with updated
+ packages which might result in changes of read-ahead
+ patterns.
+
+ * We now temporaritly lower the kernel's read_ahead_kb variable
+ when collecting read-ahead data to ensure the kernel's
+ built-in read-ahead does not add noise to our measurements
+ of necessary blocks to pre-cache.
+
+ * There's now RequiresMountsFor= to add automatic dependencies
+ for all mounts necessary for a specific file system path.
+
+ * MountAuto= and SwapAuto= have been removed from
+ system.conf. Mounting file systems at boot has to take place
+ in systemd now.
+
+ * nspawn now learned a new switch --uuid= to set the machine
+ ID on the command line.
+
+ * nspawn now loearned the -b switch to automatically search
+ for an init system.
+
+ * vt102 is now the default TERM for serial TTYs, upgraded from
+ vt100.
+
+ * systemd-logind now works on VT-less systems.
+
+ * The build tree has been reorganized. The individual
+ componets now have directories of their own.
+
+ * A new condition type ConditionPathIsReadWrite= is now available.
+
+ * nspawn learned the new -C switch to create cgroups for the
+ container in other hierarchies.
+
+ * We now have support for hardware watchdogs, configurable in
+ system.conf.
+
+ * The scheduled shutdown logic now has a public API.
+
+ * We now mount /tmp as tmpfs by default, but this can be
+ masked and /etc/fstab can override it.
+
+ * Since udisks doesn't make use of /media anymore we are not
+ mounting a tmpfs on it anymore.
+
+ * journalctl gained a new --local switch to only interleave
+ locally generated journal files.
+
+ * We can now load the IMA policy at boot automatically.
+
+ * The GTK tools have been split off into a systemd-ui.
