This adds two new setting TasksAccounting= and TasksMax= to each unit, as well as a - gloabl option DefaultTasksAccounting=. + global option DefaultTasksAccounting=. * Support for the "net_cls" cgroup controller has been added. - It allows assigning a net class ID to each task in the cgroup, - which can then be used in firewall rules and traffic shaping - configurations.

Note that the kernel netfilter net + class code does not currently work reliably for ingress + packets on unestablished sockets. This adds a new config directive called NetClass= to CGroup - enabled units. Allowed values are positive numbers for fix + enabled units. Allowed values are positive numbers for fixed assignments and "auto" for picking a free value automatically. - * The PrivateTmp, PrivateDevices, PrivateNetwork, - NoNewPrivileges, TTYPath, WorkingDirectory and RootDirectory - properties can now be set for transient units. + * 'systemctl is-system-running' now returns 'offline' if the + system is not booted with systemd. This command can now be + used as a substitute for 'systemd-notify --booted'. + + * Watchdog timeouts have been increased to 3 minutes for all + in-tree service files. Apparently, disk IO issues are more + frequent than we hoped, and user reported >1 minute waiting + for disk IO. + + * 'machine-id-commit' functionality has been merged into + 'machine-id-setup --commit'. The separate binary has been + removed. + + * The WorkingDirectory= directive in unit files may now be + set to the special value '~'. In this case, the working + directory is set to the home directory of the user configured + in User=. + + * "machinectl shell" will now open the shell in the home + directory of the selected user by default. + + * A new systemd.crash_reboot=1 kernel command line option has + been added that triggers a reboot after crashing. This can + also be set through CrashReboot= in systemd.conf. + + * The CrashChVT= configuration file setting is renamed to + CrashChangeVT=, following our usual logic of not abbreviating + unnecessarily. The old directive is still supported for compat + reasons. Also, this directive now takes an integer value + between 1 and 63, or a boolean value. The formerly supported + '-1' value for disabling stays around for compat reasons. + + * The PrivateTmp=, PrivateDevices=, PrivateNetwork=, + NoNewPrivileges=, TTYPath=, WorkingDirectory= and + RootDirectory= properties can now be set for transient + units. - * Galician, Turkish and Korean translations were added. + * The systemd-analyze tool gained a new "set-log-target" verb + to change the logging target the system manager logs to + dynamically during runtime. This is similar to how + "systemd-analyze set-log-level" already changes the log + level. + + * In nspawn /sys is now mounted as tmpfs, with only a selected + set of subdirectories mounted in from the real sysfs. This + enhances security slightly, and is useful for ensuring user + namespaces work correctly. + + * Support for USB FunctionFS activation has been added. This + allows implementation of USB gadget services that are + activated as soon as they are requested, so that they don't + have to run continously, similar to classic socket + activation. + + * The "systemctl exit" command now optionally takes an + additional parameter that sets the exit code to return from + the systemd manager when exiting. This is only relevant when + running the systemd user instance, or when running the + system instance in a container. + + * sd-bus gained the new API calls sd_bus_path_encode_many() + and sd_bus_path_decode_many() that allow easy encoding and + decoding of multiple identifier strings inside a D-Bus + object path. Another new call sd_bus_default_flush_close() + has been added to flush and close per-thread default + connections. + + * systemd-cgtop gained support for a -M/--machine= switch to + show the control groups within a certain container only. + + * "systemctl kill" gained support for an optional --fail + switch. If specified the requested operation will fail of no + processes have been killed, because the unit had no + processes attached, or similar. + + * A new (still internal) libary API sd-ipv4acd has been added, + that implements address conflict detection for IPv4. It's + based on code from sd-ipv4ll, and will be useful for + detecting DHCP address conflicts. + + * The RuntimeDirectory= setting now understands unit + specifiers like %i or %f. + + * networkd gained support for setting the IPv6 Router + Advertisment settings via IPv6AcceptRouterAdvertisements= in + .network files. + + * udev will now create /dev/disk/by-path links for ATA devices + on kernels where that is supported. + + * When downloading tar or raw images using "machinectl + pull-tar" or "machinectl pull-raw", a matching ".nspawn" + file is now also downloaded, if it is available and stored + next to the image file. + + * Units of type ".socket" gained a new boolean setting + Writable= which is only useful in conjunction with + ListenSpecial=. If true, enables opening the specified + special file in O_RDWR mode rather than O_RDONLY mode. + + * systemd-rfkill has been reworked to become a singleton + service that is activated through /dev/rfkill on each rfkill + state change and saves the settings to disk. This way, + systemd-rfkill is now compatible with devices that exist + only intermittendly, and even restores state if the previous + system shutdown was abrupt rather than clean. + + * Galician, Serbian, Turkish and Korean translations were added.
