Hi! I am happy to announce systemd 236:
https://github.com/systemd/systemd/archive/v236.tar.gz Enjoy! CHANGES WITH 236: * The modprobe.d/ drop-in for the bonding.ko kernel module introduced in v235 has been extended to also set the dummy.ko module option numdummies=0, preventing the kernel from automatically creating dummy0. All dummy interfaces must now be explicitly created. * Unknown '%' specifiers in configuration files are now rejected. This applies to units and tmpfiles.d configuration. Any percent characters that are followed by a letter or digit that are not supposed to be interpreted as the beginning of a specifier should be escaped by doubling ("%%"). (So "size=5%" is still accepted, as well as "size=5%,foo=bar", but not "LABEL=x%y%z" since %y and %z are not valid specifiers today.) * systemd-resolved now maintains a new dynamic /run/systemd/resolve/stub-resolv.conf compatibility file. It is recommended to make /etc/resolv.conf a symlink to it. This file points at the systemd-resolved stub DNS 127.0.0.53 resolver and includes dynamically acquired search domains, achieving more correct DNS resolution by software that bypasses local DNS APIs such as NSS. * The "uaccess" udev tag has been dropped from /dev/kvm and /dev/dri/renderD*. These devices now have the 0666 permissions by default (but this may be changed at build-time). /dev/dri/renderD* will now be owned by the "render" group along with /dev/kfd. * "DynamicUser=yes" has been enabled for systemd-timesyncd.service, systemd-journal-gatewayd.service and systemd-journal-upload.service. This means "nss-systemd" must be enabled in /etc/nsswitch.conf to ensure the UIDs assigned to these services are resolved properly. * In /etc/fstab two new mount options are now understood: x-systemd.makefs and x-systemd.growfs. The former has the effect that the configured file system is formatted before it is mounted, the latter that the file system is resized to the full block device size after it is mounted (i.e. if the file system is smaller than the partition it resides on, it's grown). This is similar to the fsck logic in /etc/fstab, and pulls in [email protected] and [email protected] as necessary, similar to [email protected]. Resizing is currently only supported on ext4 and btrfs. * In systemd-networkd, the IPv6 RA logic now optionally may announce DNS server and domain information. * Support for the LUKS2 on-disk format for encrypted partitions has been added. This requires libcryptsetup2 during compilation and runtime. * The systemd --user instance will now signal "readiness" when its basic.target unit has been reached, instead of when the run queue ran empty for the first time. * Tmpfiles.d with user configuration are now also supported. systemd-tmpfiles gained a new --user switch, and snippets placed in ~/.config/user-tmpfiles.d/ and corresponding directories will be executed by systemd-tmpfiles --user running in the new systemd-tmpfiles-setup.service and systemd-tmpfiles-clean.service running in the user session. * Unit files and tmpfiles.d snippets learnt three new % specifiers: %S resolves to the top-level state directory (/var/lib for the system instance, $XDG_CONFIG_HOME for the user instance), %C resolves to the top-level cache directory (/var/cache for the system instance, $XDG_CACHE_HOME for the user instance), %L resolves to the top-level logs directory (/var/log for the system instance, $XDG_CONFIG_HOME/log/ for the user instance). This matches the existing %t specifier, that resolves to the top-level runtime directory (/run for the system instance, and $XDG_RUNTIME_DIR for the user instance). * journalctl learnt a new parameter --output-fields= for limiting the set of journal fields to output in verbose and JSON output modes. * systemd-timesyncd's configuration file gained a new option RootDistanceMaxSec= for setting the maximum root distance of servers it'll use, as well as the new options PollIntervalMinSec= and PollIntervalMaxSec= to tweak the minimum and maximum poll interval. * bootctl gained a new command "list" for listing all available boot menu items on systems that follow the boot loader specification. * systemctl gained a new --dry-run switch that shows what would be done instead of doing it, and is currently supported by the shutdown and sleep verbs. * ConditionSecurity= can now detect the TOMOYO security module. * Unit file [Install] sections are now also respected in unit drop-in files. This is intended to be used by drop-ins under /usr/lib/. * systemd-firstboot may now also set the initial keyboard mapping. * Udev "changed" events for devices which are exposed as systemd .device units are now propagated to units specified in ReloadPropagatedFrom= as reload requests. * If a udev device has a SYSTEMD_WANTS= property containing a systemd unit template name (i.e. a name in the form of '[email protected]', without the instance component between the '@' and - the '.'), then the escaped sysfs path of the device is automatically used as the instance. * SystemCallFilter= in unit files has been extended so that an "errno" can be specified individually for each system call. Example: SystemCallFilter=~uname:EILSEQ. * The cgroup delegation logic has been substantially updated. Delegate= now optionally takes a list of controllers (instead of a boolean, as before), which lists the controllers to delegate at least. * The networkd DHCPv6 client now implements the FQDN option (RFC 4704). * A new LogLevelMax= setting configures the maximum log level any process of the service may log at (i.e. anything with a lesser priority than what is specified is automatically dropped). A new LogExtraFields= setting allows configuration of additional journal fields to attach to all log records generated by any of the unit's processes. * New StandardInputData= and StandardInputText= settings along with the new option StandardInput=data may be used to configure textual or binary data that shall be passed to the executed service process via standard input, encoded in-line in the unit file. * StandardInput=, StandardOutput= and StandardError= may now be used to connect stdin/stdout/stderr of executed processes directly with a file or AF_UNIX socket in the file system, using the new "file:" option. * A new unit file option CollectMode= has been added, that allows tweaking the garbage collection logic for units. It may be used to tell systemd to garbage collect units that have failed automatically (normally it only GCs units that exited successfully). systemd-run and systemd-mount expose this new functionality with a new -G option. * "machinectl bind" may now be used to bind mount non-directories (i.e. regularfiles, devices, fifos, sockets). * systemd-analyze gained a new verb "calendar" for validating and testing calendar time specifications to use for OnCalendar= in timer units. Besides validating the expression it will calculate the next time the specified expression would elapse. * In addition to the pre-existing FailureAction= unit file setting there's now SuccessAction=, for configuring a shutdown action to execute when a unit completes successfully. This is useful in particular inside containers that shall terminate after some workload has been completed. Also, both options are now supported for all unit types, not just services. * networkds's IP rule support gained two new options IncomingInterface= and OutgoingInterface= for configuring the incoming and outgoing interfaces of configured rules. systemd-networkd also gained support for "vxcan" network devices. * networkd gained a new setting RequiredForOnline=, taking a boolean. If set, systemd-wait-online will take it into consideration when determining that the system is up, otherwise it will ignore the interface for this purpose. * The sd_notify() protocol gained support for a new operation: with FDSTOREREMOVE=1 file descriptors may be removed from the per-service store again, ahead of POLLHUP or POLLERR when they are removed anyway. * A new document UIDS-GIDS.md has been added to the source tree, that documents the UID/GID range and assignment assumptions and requirements of systemd. * The watchdog device PID 1 will ping may now be configured through the WatchdogDevice= configuration file setting, or by setting the systemd.watchdog_service= kernel commandline option. * systemd-resolved's gained support for registering DNS-SD services on the local network using MulticastDNS. Services may either be registered by dropping in a .dnssd file in /etc/systemd/dnssd/ (or the same dir below /run, /usr/lib), or through its D-Bus API. * The sd_notify() protocol can now with EXTEND_TIMEOUT_USEC=microsecond extend the effective start, runtime, and stop time. The service must continue to send EXTEND_TIMEOUT_USEC within the period specified to prevent the service manager from making the service as timedout. * systemd-resolved's DNSSEC support gained support for RFC 8080 (Ed25519 keys and signatures). * The systemd-resolve command line tool gained a new set of options --set-dns=, --set-domain=, --set-llmnr=, --set-mdns=, --set-dnssec=, --set-nta= and --revert to configure per-interface DNS configuration dynamically during runtime. It's useful for pushing DNS information into systemd-resolved from DNS hook scripts that various interface managing software supports (such as pppd). * systemd-nspawn gained a new --network-namespace-path= command line option, which may be used to make a container join an existing network namespace, by specifying a path to a "netns" file.
