Thus, it should be unnecessary to provide any + scriptlets to execute this configuration from package installation + scripts. + + * systemd-sysusers gained a mode where the configuration to execute is + specified on the command line, but this configuration is not executed + directly, but instead it is merged with the configuration on disk, + and the result is executed. This is useful for package installation + scripts which want to create the user before installing any files on + disk (in case some of those files are owned by that user), while + still allowing local admin overrides. + + This functionality is exposed to rpm scriplets through a new + %sysusers_create_package macro. Old %sysusers_create and + %sysusers_create_inline macros are deprecated. + + A transfiletrigger for sysusers.d configuration is now installed, + which means that it should be uncessary to call systemd-sysusers from + package installation scripts, unless the package installs any files + owned by those newly-created users, in which case + %sysusers_create_package should be used. + + * Analogous change has been done for systemd-tmpfiles: it gained a mode + where the command-line configuration is merged with the configuration + on disk. This is exposed as the new %tmpfiles_create_package macro, + and %tmpfiles_create is deprecated. A transfiletrigger is installed + for tmpfiles.d, hence it should be unnecessary to call systemd-tmpfiles + from package installation scripts. + + * sysusers.d configuration for a user may now also specify the group + number, in addition to the user number ("u username 123:456"), or + without the user number ("u username -:456"). + + * Configution items for systemd-sysusers can now be specified as + positional arguments when the new --inline switch is used. + + * The login shell of users created through sysusers.d may now be + specified (previously, it was always /bin/sh for root and + /sbin/nologin for other users). + + * systemd-analyze gained a new --global switch to look at global user + configuration. It also gained a unit-paths verb to list the unit load + paths that are compiled into systemd (which can be used with + --systemd, --user, or --global). + + * udevadm trigger gained a new --settle/-w option to wait for any + triggered events to finish (but just those, and not any other events + which are triggered meanwhile). + + * The action that systemd-logind takes when the lid is closed and the + machine is connected to external power can now be configured using + HandleLidSwitchExternalPower= in logind.conf. Previously, this action + was determined by HandleLidSwitch=, and, for backwards compatibility, + is still is, if HandleLidSwitchExternalPower= is not explicitly set. + + * journalctl will periodically call sd_journal_process() to make it + resilient against inotify queue overruns when journal files are + rotated very quickly. + + * Two new functions in libsystemd — sd_bus_get_n_queued_read and + sd_bus_get_n_queued_write — may be used to check the number of + pending bus messages. + + * systemd gained a new + org.freedesktop.systemd1.Manager.AttachProcessesToUnit dbus call + which can be used to migrate foreign processes to scope and service + units. The primary user for this new API is systemd itself: the + systemd --user instance uses this call of the systemd --system + instance to migrate processes if it itself gets the request to + migrate processes and the kernel refuses this due to access + restrictions. Thanks to this "systemd-run --scope --user …" works + again in pure cgroups v2 environments when invoked from the user + session scope. + + * A new TemporaryFileSystem= setting can be used to mask out part of + the real file system tree with tmpfs mounts. This may be combined + with BindPaths= and BindReadOnlyPaths= to hide files or directories + not relevant to the unit, while still allowing some paths lower in + the tree to be accessed. + + ProtectHome=tmpfs may now be used to hide user home and runtime + directories from units, in a way that is mostly equivalent to + "TemporaryFileSystem=/home /run/user /root". + + * Non-service units are now started with KeyringMode=shared by default. + This means that mount and swapon and other mount tools have access + to keys in the main keyring. + + * /sys/fs/bpf is now mounted automatically. + + * QNX virtualization is now detected by systemd-detect-virt and may + be used in ConditionVirtualization=. + + * IPAccounting= may now be enabled also for slice units. + + * A new -Dsplit-bin= build configuration switch may be used to specify + whether bin and sbin directories are merged, or if they should be + included separately in $PATH and various listings of executable + directories. The build configuration scripts will try to autodetect + the proper values of -Dsplit-usr= and -Dsplit-bin= based on build + system, but distributions are encouraged to configure this + explicitly. + + * A new -Dok-color= build configuration switch may be used to change + the colour of "OK" status messages. + + * UPGRADE ISSUE: serialization of units using JoinsNamespaceOf= with + PrivateNetwork=yes was buggy in previous versions of systemd. This + means that after the upgrade and daemon-reexec, any such units must + be restarted. + + * INCOMPATIBILITY: as announced in the NEWS for 237, systemd-tmpfiles + will not exclude read-only files owned by root from cleanup. + CHANGES WITH 237: * Some keyboards come with a zoom see-saw or rocker which until now got |
