(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). + + Contributions from Allin Cottrell, Auke Kok, Brandon Philips, + Colin Guthrie, Colin Walters, Daniel J Walsh, Dave Reisner, + Eelco Dolstra, Jan Engelhardt, Kay Sievers, Lennart + Poettering, Lucas De Marchi, Lukas Nykryn, Mantas Mikulėnas, + Martin Pitt, Matthias Clasen, Michael Olbrich, Pierre Schmitz, + Shawn Landden, Thomas Hindoe Paaboel Andersen, Tom Gundersen, + Václav Pavlín, Yin Kangkai, Zbigniew Jędrzejewski-Szmek + +CHANGES WITH 189: + + * Support for reading structured kernel messages from + /dev/kmsg has now been added and is enabled by default. + + * Support for reading kernel messages from /proc/kmsg has now + been removed. If you want kernel messages in the journal + make sure to run a recent kernel (>= 3.5) that supports + reading structured messages from /dev/kmsg (see + above). /proc/kmsg is now exclusive property of classic + syslog daemons again. + + * The libudev API gained the new + udev_device_new_from_device_id() call. + + * The logic for file system namespace (ReadOnlyDirectory=, + ReadWriteDirectoy=, PrivateTmp=) has been reworked not to + require pivot_root() anymore. This means fewer temporary + directories are created below /tmp for this feature. + + * nspawn containers will now see and receive all submounts + made on the host OS below the root file system of the + container. + + * Forward Secure Sealing is now supported for Journal files, + which provide cryptographical sealing of journal files so + that attackers cannot alter log history anymore without this + being detectable. Lennart will soon post a blog story about + this explaining it in more detail. + + * There are two new service settings RestartPreventExitStatus= + and SuccessExitStatus= which allow configuration of exit + status (exit code or signal) which will be excepted from the + restart logic, resp. consider successful. + + * journalctl gained the new --verify switch that can be used + to check the integrity of the structure of journal files and + (if Forward Secure Sealing is enabled) the contents of + journal files. + + * nspawn containers will now be run with /dev/stdin, /dev/fd/ + and similar symlinks pre-created. This makes running shells + as container init process a lot more fun. + + * The fstab support can now handle PARTUUID= and PARTLABEL= + entries. + + * A new ConditionHost= condition has been added to match + against the hostname (with globs) and machine ID. This is + useful for clusters where a single OS image is used to + provision a large number of hosts which shall run slightly + different sets of services. + + * Services which hit the restart limit will now be placed in a + failure state. + + Contributions from Bertram Poettering, Dave Reisner, Huang + Hang, Kay Sievers, Lennart Poettering, Lukas Nykryn, Martin + Pitt, Simon Peeters, Zbigniew Jędrzejewski-Szmek + +CHANGES WITH 188: + + * When running in --user mode systemd will now become a + subreaper (PR_SET_CHILD_SUBREAPER). This should make the ps + tree a lot more organized. + + * A new PartOf= unit dependency type has been introduced that + may be used to group services in a natural way. + + * "systemctl enable" may now be used to enable instances of + services. + + * journalctl now prints error log levels in red, and + warning/notice log levels in bright white. It also supports + filtering by log level now. + + * cgtop gained a new -n switch (similar to top), to configure + the maximum number of iterations to run for. It also gained + -b, to run in batch mode (accepting no input). + + * The suffix ".service" may now be ommited on most systemctl + command lines involving service unit names. + + * There's a new bus call in logind to lock all sessions, as + well as a loginctl verb for it "lock-sessions". + + * libsystemd-logind.so gained a new call sd_journal_perror() + that works similar to libc perror() but logs to the journal + and encodes structured information about the error number. + + * /etc/crypttab entries now understand the new keyfile-size= + option. + + * shutdown(8) now can send a (configurable) wall message when + a shutdown is cancelled. + + * The mount propagation mode for the root file system will now + default to "shared", which is useful to make containers work + nicely out-of-the-box so that they receive new mounts from + the host. This can be undone locally by running "mount + --make-rprivate /" if needed. + + * The prefdm.service file has been removed. Distributions + should maintain this unit downstream if they intend to keep + it around. However, we recommend writing normal unit files + for display managers instead. + + * Since systemd is a crucial part of the OS we will now + default to a number of compiler switches that improve + security (hardening) such as read-only relocations, stack + protection, and suchlike. + + * The TimeoutSec= setting for services is now split into + TimeoutStartSec= and TimeoutStopSec= to allow configuration + of individual time outs for the start and the stop phase of + the service. + + Contributions from: Artur Zaprzala, Arvydas Sidorenko, Auke + Kok, Bryan Kadzban, Dave Reisner, David Strauss, Harald Hoyer, + Jim Meyering, Kay Sievers, Lennart Poettering, Mantas + Mikulėnas, Martin Pitt, Michal Schmidt, Michal Sekletar, Peter + Alfredsen, Shawn Landden, Simon Peeters, Terence Honles, Tom + Gundersen, Zbigniew Jędrzejewski-Szmek + +CHANGES WITH 187: + + * The journal and id128 C APIs are now fully documented as man + pages. + + * Extra safety checks have been added when transitioning from + the initial RAM disk to the main system to avoid accidental + data loss. + + * /etc/crypttab entries now understand the new keyfile-offset= + option. + + * systemctl -t can now be used to filter by unit load state. + + * The journal C API gained the new sd_journal_wait() call to + make writing synchronous journal clients easier. + + * journalctl gained the new -D switch to show journals from a + specific directory. + + * journalctl now displays a special marker between log + messages of two different boots. + + * The journal is now explicitly flushed to /var via a service + systemd-journal-flush.service, rather than implicitly simply + by seeing /var/log/journal to be writable. + + * journalctl (and the journal C APIs) can now match for much + more complex expressions, with alternatives and + disjunctions. + + * When transitioning from the initial RAM disk to the main + system we will now kill all processes in a killing spree to + ensure no processes stay around by accident. + + * Three new specifiers may be used in unit files: %u, %h, %s + resolve to the user name, user home directory resp. user + shell. This is useful for running systemd user instances. + + * We now automatically rotate journal files if their data + object hash table gets a fill level > 75%. We also size the + hash table based on the configured maximum file size. This + together should lower hash collisions drastically and thus + speed things up a bit. + + * journalctl gained the new "--header" switch to introspect + header data of journal files. + + * A new setting SystemCallFilters= has been added to services + which may be used to apply blacklists or whitelists to + system calls. This is based on SECCOMP Mode 2 of Linux 3.5. + + * nspawn gained a new --link-journal= switch (and quicker: -j) + to link the container journal with the host. This makes it + very easy to centralize log viewing on the host for all + guests while still keeping the journal files separated. + + * Many bugfixes and optimizations + + Contributions from: Auke Kok, Eelco Dolstra, Harald Hoyer, Kay + Sievers, Lennart Poettering, Malte Starostik, Paul Menzel, Rex + Tsai, Shawn Landden, Tom Gundersen, Ville Skyttä, Zbigniew + Jędrzejewski-Szmek + +CHANGES WITH 186: + + * Several tools now understand kernel command line arguments, + which are only read when run in an initial RAM disk. 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.
