They + usually follow closely their normal counterparts, but are + prefixed with rd. + + * There's a new tool to analyze the readahead files that are + automatically generated at boot. Use: + + /usr/lib/systemd/systemd-readahead analyze /.readahead + + * We now provide an early debug shell on tty9 if this enabled. Use: + + systemctl enable debug-shell.service + + * All plymouth related units have been moved into the Plymouth + package. Please make sure to upgrade your Plymouth version + as well. + + * systemd-tmpfiles now supports getting passed the basename of + a configuration file only, in which case it will look for it + in all appropriate directories automatically. + + * udevadm info now takes a /dev or /sys path as argument, and + does the right thing. Example: + + udevadm info /dev/sda + udevadm info /sys/class/block/sda + + * systemctl now prints a warning if a unit is stopped but a + unit that might trigger it continues to run. Example: a + service is stopped but the socket that activates it is left + running. + + * "systemctl status" will now mention if the log output was + shortened due to rotation since a service has been started. + + * The journal API now exposes functions to determine the + "cutoff" times due to rotation. + + * journald now understands SIGUSR1 and SIGUSR2 for triggering + immediately flushing of runtime logs to /var if possible, + resp. for triggering immediate rotation of the journal + files. + + * It is now considered an error if a service is attempted to + be stopped that is not loaded. + + * XDG_RUNTIME_DIR now uses numeric UIDs instead of usernames. + + * systemd-analyze now supports Python 3 + + * tmpfiles now supports cleaning up directories via aging + where the first level dirs are always kept around but + directories beneath it automatically aged. This is enabled + by prefixing the age field with '~'. + + * Seat objects now expose CanGraphical, CanTTY properties + which is required to deal with very fast bootups where the + display manager might be running before the graphics drivers + completed initialization. + + * Seat objects now expose a State property. + + * We now include RPM macros for service enabling/disabling + based on the preset logic. We recommend RPM based + distributions to make use of these macros if possible. This + makes it simpler to reuse RPM spec files across + distributions. + + * We now make sure that the collected systemd unit name is + always valid when services log to the journal via + STDOUT/STDERR. + + * There's a new man page kernel-command-line(7) detailing all + command line options we understand. + + * The fstab generator may now be disabled at boot by passing + fstab=0 on the kernel command line. + + * A new kernel command line option modules-load= is now understood + to load a specific kernel module statically, early at boot. + + * Unit names specified on the systemctl command line are now + automatically escaped as needed. Also, if file system or + device paths are specified they are automatically turned + into the appropriate mount or device unit names. Example: + + systemctl status /home + systemctl status /dev/sda + + * The SysVConsole= configuration option has been removed from + system.conf parsing. + + * The SysV search path is no longer exported on the D-Bus + Manager object. + + * The Names= option is been removed from unit file parsing. + + * There's a new man page bootup(7) detailing the boot process. + + * Every unit and every generator we ship with systemd now + comes with full documentation. The self-explanatory boot is + complete. + + * A couple of services gained "systemd-" prefixes in their + name if they wrap systemd code, rather than only external + code. Among them fsck@.service which is now + systemd-fsck@.service. + + * The HaveWatchdog property has been removed from the D-Bus + Manager object. + + * systemd.confirm_spawn= on the kernel command line should now + work sensibly. + + * There's a new man page crypttab(5) which details all options + we actually understand. + + * systemd-nspawn gained a new --capability= switch to pass + additional capabilities to the container. + + * timedated will now read known NTP implementation unit names + from /usr/lib/systemd/ntp-units.d/*.list, + systemd-timedated-ntp.target has been removed. + + * journalctl gained a new switch "-b" that lists log data of + the current boot only. + + * The notify socket is in the abstract namespace again, in + order to support daemons which chroot() at start-up. + + * There is a new Storage= configuration option for journald + which allows configuration of where log data should go. This + also provides a way to disable journal logging entirely, so + that data collected is only forwarded to the console, the + kernel log buffer or another syslog implementation. + + * Many bugfixes and optimizations. + + Contributions from: Auke Kok, Colin Guthrie, Dave Reisner, + David Strauss, Eelco Dolstra, Kay Sievers, Lennart Poettering, + Lukas Nykryn, Michal Schmidt, Michal Sekletar, Paul Menzel, + Shawn Landden, Tom Gundersen + +CHANGES WITH 185: + * "systemctl help " now shows the man page if one is + available. + + * Several new man pages have been added. + + * MaxLevelStore=, MaxLevelSyslog=, MaxLevelKMsg=, + MaxLevelConsole= can now be specified in + journald.conf. These options allow reducing the amount of + data stored on disk or forwarded by the log level. + + * TimerSlackNSec= can now be specified in system.conf for + PID1. This allows system-wide power savings. + + Contributions from: Dave Reisner, Kay Sievers, Lauri Kasanen, + Lennart Poettering, Malte Starostik, Marc-Antoine Perennou, + Matthias Clasen + +CHANGES WITH 184: + * logind is now capable of (optionally) handling power and + sleep keys as well as the lid switch. + + * journalctl now understands the syntax "journalctl + /usr/bin/avahi-daemon" to get all log output of a specific + daemon. + + * CapabilityBoundingSet= in system.conf now also influences + the capability bound set of usermode helpers of the kernel. + + Contributions from: Daniel Drake, Daniel J. Walsh, Gert + Michael Kulyk, Harald Hoyer, Jean Delvare, Kay Sievers, + Lennart Poettering, Matthew Garrett, Matthias Clasen, Paul + Menzel, Shawn Landden, Tero Roponen, Tom Gundersen + +CHANGES WITH 183: + * Note that we skipped 139 releases here in order to set the + new version to something that is greater than both udev's + and systemd's most recent version number. + + * 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 loginctl and journalctl to match systemctl. + + * The config files: /etc/systemd/systemd-logind.conf and + /etc/systemd/systemd-journald.conf have been renamed to + 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 + particular 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 the 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 CapabilityBoundingSet= option to + globally reduce the set of capabilities 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 anymore. + + * 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 learned 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 + components 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. + + Contributions from: Andreas Schwab, Auke Kok, Ayan George, + Colin Guthrie, Daniel Mack, Dave Reisner, David Ward, Elan + Ruusamäe, Frederic Crozat, Gergely Nagy, Guillermo Vidal, + Hannes Reinecke, Harald Hoyer, Javier Jardón, Kay Sievers, + Lennart Poettering, Lucas De Marchi, Léo Gillot-Lamure, + Marc-Antoine Perennou, Martin Pitt, Matthew Monaco, Maxim + A.
