* Support for cgroup v1 ('legacy' and 'hybrid' hierarchies) is now
|
||||
considered obsolete and systemd by default will refuse to boot under it.
|
||||
To forcibly reenable cgroup v1 support, SYSTEMD_CGROUP_ENABLE_LEGACY_FORCE=1
|
||||
must be set on kernel command line. The meson option 'default-hierarchy='
|
||||
is also deprecated, i.e. only cgroup v2 ('unified' hierarchy) can be
|
||||
selected as build-time default.

* Previously, systemd-networkd did not explicitly remove any bridge VLAN
|
||||
IDs assigned on bridge master and ports. Since v256, if a .network
|
||||
file for an interface has at least one valid settings in [BridgeVLAN]
|

section, then all assigned VLAN IDs on the interface that are not
|
||||
configured in the .network file are removed.

* systemd-gpt-auto-generator will stop generating units for ESP or
|
||||
XBOOTLDR partitions if it finds mount entries in the /boot/ or /efi/
|
||||
hierarchies in fstab. This is to prevent the generator from
|

interfering with systems where ESP is explicitly configured to be

mounted at some path, for example /boot/efi/ (this type of setup is
|

obsolete but is still commonly found).

and related services, and SYSTEMD_HOME_LOCK_FREEZE_SESSION=false for
|
||||
systemd-homed.service.
|
||||
|
||||
* systemd-tmpfiles and systemd-sysusers, when given a relative path
|
||||
(with at least one directory separator '/'), will open the file
|
||||
directly, instead of searching for the given partial path in the
|
||||
standard locations. The old mode wasn't useful because tmpfiles.d and
|
||||
sysusers.d configuratino has a flat structure with no subdirectories
|
||||
under the standard locations and this change makes it easier to work
|
||||
with local files with those tools.
|
||||
|
||||
* systemd-tmpfiles now properly applies nested configuration to 'R' and
|
||||
'D' stanzas. For example, with 'R /foo; x /foo/bar', /foo/bar will
|
||||
now be excluded from removal.
|
||||
|
||||
General Changes and New Features:
|
||||
|
||||
* Various programs will load the main configuration from under
|
||||
/usr/lib/, /usr/local/lib, and /run, not just from under /etc/. For
|
||||
example, systemd-logind will look for /etc/systemd/logind.conf,
|
||||
/run/systemd/logind.conf, /usr/local/lib/systemd/logind.conf, and
|
||||
/usr/lib/systemd/logind.conf, and use the first file that is found.
|
||||
This means that the location logic for the main config file and for
|
||||
drop-ins is now the same.
|
||||
|
||||
ukify will look for the config files in /usr/lib/kernel/ and the
|
||||
other locations, and now also supports drop-ins.
|
||||
|
||||
systemd-udevd now supports drop-ins for udev.conf.
|
||||
|
||||
* A new 'systemd-vpick' binary has been added. It implements the new
|
||||
vpick protocol, where a .v directory may contain multiple files with
|
||||
a version embedded in the name, and they may be ordered by version
|
||||
and the newest one can be reliably selected.
|
||||
|
||||
systemd-nspawn, systemd-dissect, and the RootDirectory=, RootImage=,
|
||||
ExtensionImages=, and ExtensionDirectories= settings for units now
|
||||
support the vpick protocol and allow the latest version to be
|
||||
selected automatically if a "*.v/" directory is specified as the
|
||||
source.
|
||||
|
||||
* Credentials can now be made accessible to unprivileged users.
|
||||
'systemd-creds --user --uid=<user>' will encrypt or decrypt a
|
||||
credential for a specific user.
|
||||
|
||||
* With systemd-homed, it is now possible to log in and activate an
|
||||
encrypted home area over SSH.
|
||||
|
||||
homectl is now installed as a multi-call binary. When invoked as
|
||||
systemd-home-fallback-shell it can be used as a temporary shell which
|
||||
allows the home area to interactively unlocked. When the home area
|
||||
becomes available, the temporary shell executes the normal one.
|
||||
|
||||
systemd-homed gained new methods
|
||||
org.freedesktop.home1.Manager.RefHomeUnrestricted,
|
||||
org.freedesktop.home1.Home.RefUnrestricted,
|
||||
org.freedesktop.home1.Manager.ActivateHomeIfReferenced, and
|
||||
org.freedesktop.home1.Home.ActivateIfReferenced to allow logging in
|
||||
without activating the home area and then activating the home area
|
||||
later.
|
||||
|
||||
* JSON User Records have been extended with a separate storage area
|
||||
called "User Record Blob Directories". This is intended to store the
|
||||
user's background image, avatar picture, and other similar items
|
||||
which are too large to fit into the User Record itself.
|
||||
|
||||
systemd-homed, userdbctl, and homectl gained support for blob
|
||||
directories.
|
||||
|
||||
* New command-line tool 'importctl' is added with the following verbs:
|
||||
pull-tar, pull-raw, import-tar, import-raw, import-fs, export-tar,
|
||||
export-raw, list-transfers, cancel-transfer.
|
||||
|
||||
Service Manager:
|
||||
|
||||
* New manager setting ProtectSystem= has been added. It is analogous to
|
||||
the unit setting, but applies to the whole system. It is enabled by
|
||||
default in the initrd.
|
||||
|
||||
* New unit setting WantsMountsFor= has been added. It is analogous to
|
||||
RequiresMountsFor=, but with a Wants= dependency instead of
|
||||
Requires=. This new logic is used in various places where mounts were
|
||||
added as dependencies for other settings (WorkingDirectory=-…,
|
||||
PrivateTmp=yes, cryptsetup lines with 'nofail').
|
||||
|
||||
* New unit setting MemoryZSwapWriteback= can be used to control the new
|
||||
memory.zswap.writeback cgroup knob added in kernel 6.8.
|
||||
|
||||
* The manager gained a org.freedesktop.systemd1.StartAuxiliaryScope()
|
||||
method to devolve some processes from a service into a new scope.
|
||||
This new scope will remain even if the original service unit is
|
||||
restarted. Cgroup properties of the new scope are copied from the
|
||||
service, so various limits are retained.
|
||||
|
||||
* Units now expose properties EffectiveMemoryMax=,
|
||||
EffectiveMemoryHigh=, and EffectiveTasksMax=, which report the
|
||||
most stringent limit systemd is aware of for the given unit.
|
||||
|
||||
* A new specifier %D expands to $XDG_DATA_HOME.
|
||||
|
||||
* AllowedCPUs= now supports specifier expansion.
|
||||
|
||||
* What= setting in .mount and .swap units now accepts an fstab-style
|
||||
identifiers, for example UUID=… or LABEL=….
|
||||
|
||||
* RestrictNetworkInterfaces= now supports alternative network interface
|
||||
names.
|
||||
|
||||
* PAMName= now implies SetLoginEnvironment=yes.
|
||||
|
||||
* homectl gained a new verb 'firstboot', and a new
|
||||
systemd-homed-firstboot.service unit uses this verb to create users
|
||||
in a first boot environment, either from credentials or by querying
|
||||
interactively.
|
||||
|
||||
* systemd.firstboot=no can be used on the kernel command-line to
|
||||
disable interactive queries, but allow other first boot configuration
|
||||
to happen based on credentials.
|
||||
|
||||
* A new kernel command-line option systemd.default_debug_tty= can be
|
||||
used to specify the TTY for the debug shell, independently of
|
||||
enabling or disabling it.
|
||||
|
||||
* Systemd hostname can be configured via the systemd.hostname
|
||||
credential.
|
||||
|
||||
The Journal:
|
||||
|
||||
* systemd-journald can now forward journal entries to a socket
|
||||
(AF_INET, AF_INET6, AF_UNIX, or AF_VSOCK). The socket can be
|
||||
specified in journald.conf via a new option ForwardAddress= or via
|
||||
the 'journald.forward_address' credential.
|
||||
|
||||
* systemd-journal-remote now also accepts AF_VSOCK and AF_UNIX sockets
|
||||
(so it can be used to receive entries forwarded by systemd-journald).
|
||||
|
||||
* systemd-vmspawn gained a new --forward-journal= option to forward the
|
||||
virtual machine's journal entries to the host. This is done over a
|
||||
AF_VSOCK socket, i.e. it does not require networking in the guest.
|
||||
|
||||
* journalctl gained option '-i' as a shortcut for --file=.
|
||||
|
||||
* journalctl gained a new -T/--exclude-identifier= option to filter
|
||||
out certain syslog identifiers.
|
||||
|
||||
* journalctl gained a new --list-namespaces option.
|
||||
|
||||
* systemd-journal-gatewayd allows restricting the time range of
|
||||
retrieved entries with realtime=[<since>]:[<until>].
|
||||
|
||||
Device Management:
|
||||
|
||||
* Udev now creates symlinks that combine by-path and by-{label,uuid}
|
||||
information:
|
||||
/dev/disk/by-path/<path>/by-<label|uuid|…>/<label|uuid|…>.
|
||||
This allows distinguishing partitions with identical contents on
|
||||
multiple storage devices. This is useful, for example, when copying
|
||||
raw disk contents between devices.
|
||||
|
||||
* Udev now creates persistent /dev/media/by-path symlinks for media
|
||||
controllers. For example, the uvcvideo driver may create /dev/media0
|
||||
which will be linked as
|
||||
/dev/media/by-path/pci-0000:04:00.3-usb-0:1:1.0-media-controller.
|
||||
|
||||
* An allowlist/denylist may be specified to filter which sysfs
|
||||
attributes are used when crafting network interface names. Those
|
||||
lists are stored as HWDB entries
|
||||
ID_NET_NAME_ALLOW_<sysfsattr>=0|1
|
||||
and
|
||||
ID_NET_NAME_ALLOW=0|1.
|
||||
The goal is to avoid unexpected changes to interface names when the
|
||||
kernel is updated and new sysfs attributes become visible.
|
||||
|
||||
* A new unit tpm2.target has been added to provide a synchronization
|
||||
point for units which expect the TPM hardware to be available.
|
||||
|
||||
* systemd-backlight now properly supports numbered devices which the
|
||||
kernel creates to avoid collisions in the leds subsystem.
|
||||
|
||||
* systemd-hwdb update operation can be disabled with environment
|
||||
variable SYSTEMD_HWDB_UPDATE_BYPASS=1.
|
||||
|
||||
* systemd-logind gained a new org.freedesktop.login1.Manager.Sleep()
|
||||
method that automatically redirects to SuspendThenHibernate(),
|
||||
Suspend(), HybridSleep(), or Hibernate(), depending on what is
|
||||
supported and configured, a new configuration setting SleepOperation=,
|
||||
and an accompanying helper method
|
||||
org.freedesktop.login1.Manager.CanSleep() and property
|
||||
org.freedesktop.login1.Manager.SleepOperation.
|
||||
|
||||
'systemctl sleep' calls the new method to automatically put the
|
||||
machine to sleep in the most appropriate way.
|
||||
|
||||
* systemd-hostnamed now exposes the machine ID and boot ID via D-Bus.
|
||||
|
||||
* systemd-hostnamed now provides a Varlink interface.
|
||||
|
||||
* systemd-hostnamed exports the data in os-release(5) and
|
||||
machine-info(5) via D-Bus and Varlink.
|
||||
|
||||
Network Management:
|
||||
|
||||
* systemd-networkd now provides a Varlink interface.
|
||||
|
||||
* systemd-networkd's proxy support gained a new option to configure
|
||||
a private VLAN variant of the proxy ARP supported by the kernel
|
||||
under the name IPv4ProxyARPPrivateVLAN=.
|
||||
|
||||
* TPM 1.2 PCR measurement support has been removed from
|
||||
systemd-stub. TPM 1.2 is obsolete and — due to the (by today's
|
||||
standards) weak cryptographic algorithms it only supports — does not
|
||||
actually provide the security benefits it's supposed to
|
||||
provide. Given that the rest of systemd's codebase never supported
|
||||
TPM 1.2 the support has now been removed from systemd-stub as well.
|
||||
* systemd-networkd now exports the NamespaceId and NamespaceNSID
|
||||
properties via D-Bus and Varlink.
|
||||
|
||||
* systemd-networkd now supports IPv6RetransmissionTimeSec= and
|
||||
UseRetransmissionTime= settings in .network files to configure
|
||||
retransmission time for IPv6 neighbor solicitation messages.
|
||||
|
||||
* networkctl gained new verbs 'mask' and 'unmask'.
|
||||
|
||||
* 'networkctl edit --runtime' allows editing volatile configuration
|
||||
under /run/systemd/network/.
|
||||
|
||||
* The implementation behind TTLPropagate= network setting has been
|
||||
removed and the setting is now ignored.
|
||||
|
||||
* systemd-network-generator will now pick up .netdev/.link/.network
|
||||
configuration from credentials.
|
||||
|
||||
* systemd-networkd will now pick up wireguard configuration from
|
||||
credentials.
|
||||
|
||||
* systemd-ssh-proxy is a new SSH client plugin that allows connecting
|
||||
to AF_SOCK or AF_UNIX sockets.
|
||||
|
||||
* systemd-nspawn now provides a /run/systemd/nspawn/unix-export/
|
||||
directory where the container payload can expose AF_UNIX sockets to
|
||||
allow them them to be accessed from outside.
|
||||
|
||||
* systemd-nspawn will tint the background for container output.
|
||||
This can be controller with the new --backgroup= option.
|
||||
|
||||
* systemd-nspawn gained support for the 'owneridmap' option for bind
|
||||
mounts to map the target directory owner from inside the container to
|
||||
the owner of the directory bound from the host filesystem.
|
||||
|
||||
* A sshd config drop-in to allow ssh keys acquired via userdbctl to be
|
||||
used for authorization.
|
||||
|
||||
* New generator systemd-ssh-generator can be used to bind a
|
||||
socket-activated SSH instance to a local AF_SOCK or AF_UNIX socket.
|
||||
This generator will automaticaly bind /run/host/unix-export/ssh.
|
||||
|
||||
* systemd-resolved now implements RFC 8914 EDE error codes.
|
||||
|
||||
* systemd-resolved and resolvectl now support RFC 9460 SVCB and HTTPS
|
||||
records.
|
||||
|
||||
* resolvectl gained a new option --relax-single-label= to allow
|
||||
querying single-label hostnames via DNS.
|
||||
|
||||
Systemd-boot and systemd-stub and Related Tools:
|
||||
|
||||
* TPM 1.2 PCR measurement support has been removed from systemd-stub.
|
||||
TPM 1.2 is obsolete and — due to the (by today's standards) weak
|
||||
cryptographic algorithms it only supports — does not actually provide
|
||||
the security benefits it's supposed to provide. Given that the rest
|
||||
of systemd's codebase never supported TPM 1.2, the support has now
|
||||
been removed from systemd-stub as well.
|
||||
|
||||
* Confexts are loaded by systemd-stub from the ESP as well.
|
||||
|
||||
* The pcrlock policy is saved in an unencrypted credential file
|
||||
"pcrlock.<entry-token>.cred" under XBOOTLDR/ESP in the
|
||||
/loader/credentials/ directory. It will be picked up at boot by
|
||||
systemd-stub and passed to the initrd, where it can be used to unlock
|
||||
the root file system.
|
||||
|
||||
* kernel-install gained support for --root= for the 'list' verb.
|
||||
|
||||
* systemd-pcrlock gained an --entry-token= option to configure the
|
||||
entry-token.
|
||||
|
||||
* systemd-pcrlock now provides a Varlink interface and can be
|
||||
run as a daemon via a template unit.
|
||||
|
||||
* bootctl now provides a Varlink interface and can be run as a daemon
|
||||
via a template unit.
|
||||
|
||||
* ukify gained support for signing of PCR signatures via OpenSSL's
|
||||
engines and providers.
|
||||
|
||||
* ukify now supports zboot kernels.
|
||||
|
||||
Command-line tools:
|
||||
|
||||
* systemd-run is now a multi-call binary. When invoked as 'uid0', it
|
||||
provides as interface similar to 'sudo', with all arguments starting
|
||||
at the first non-option parameter being treated the command to
|
||||
invoke.
|
||||
|
||||
* systemd-run gained a new option '--ignore-failure' to suppress
|
||||
command failures.
|
||||
|
||||
* systemd-creds gained new options --user/--uid=.
|
||||
|
||||
* 'systemctl edit --stdin' allows creation of unit files and drop-ins
|
||||
with contents fed via standard input. This is useful when creating
|
||||
configuration programatically; the tool takes care of figuring out
|
||||
the file name, creating any directories, and reloading the manager
|
||||
afterwards.
|
||||
|
||||
* 'systemctl disable --now' and 'systemctl mask --now' now work
|
||||
correctly with template units.
|
||||
|
||||
* 'systemd-analyze architectures' lists known CPU architectures.
|
||||
|
||||
* 'systemd-analyze --json=…' is supported for 'architectures',
|
||||
'capability', 'exit-status'.
|
||||
|
||||
* 'systemd-tmpfiles --purge' will purge (remove) all files and
|
||||
directories created via tmpfiles.d configuration.
|
||||
|
||||
* systemd-id128 gained new options --no-pager, --no-legend, and
|
||||
-j/--json=.
|
||||
|
||||
* hostnamectl gained '-j' as shortcut for '--json=pretty' or
|
||||
'--json=short'.
|
||||
|
||||
* loginctl now supports -j/--json=.
|
||||
|
||||
* resolvectl now supports -j/--json= for --type=.
|
||||
|
||||
* systemd-vmspawn gained a new --firmware= option to configure or list
|
||||
firmware definitions for Qemu, a new --tpm= option to enable or
|
||||
disable the use of a software TPM, a new --linux= option to specify a
|
||||
kernel binary for direct kernel boot, a new --initrd= option to
|
||||
specify an initrd for direct kernel boot, a new -D/--directory option
|
||||
to use a plain directory as the root file system, a new
|
||||
--private-users option similar to the one in systemd-nspawn, new
|
||||
options --bind= and --bind-ro= to bind part of the host's file system
|
||||
hierarchy into the guest, a new --extra-drive= option to attach
|
||||
additional storage, and -n/--network-tap/--network-user-mode to
|
||||
configure networking.
|
||||
|
||||
* A new systemd-vmspawn@.service can be used to launch systemd-vmspawn
|
||||
as a service.
|
||||
|
||||
* varlinkctl gained support for the "ssh:" transport. This requires
|
||||
OpenSSH 9.4 or newer.
|
||||
|
||||
* varlinkctl gained a new --collect switch to collect all responses of
|
||||
a method call emitted in JSON_SEQ mode and turn them into normal
|
||||
JSON.
|
||||
|
||||
* systemd-sysext gained support for mutable system extensions, where a
|
||||
writeable upperdir is stored under /var/lib/extensions.mutable/, and
|
||||
a new --mutable option to configure this behaviour.
|
||||
|
||||
* systemd-dissect gained a new --make-archive-option to generate an
|
||||
archive file from a disk image.
|
||||
|
||||
* systemd-repart gained new options --generate-fstab= and
|
||||
--generate-crypttab= to write the fstab and crypttab files.
|
||||
|
||||
* systemd-repart gained new option --private-key-source= to specify the
|
||||
key for as a file, or via OpenSSL's "engine" or "provider" logic.
|
||||
Configures the signing mechanism to use when creating verity
|
||||
signature partitions.
|
||||
|
||||
* systemd-measure gained new options --certificate=, --private-key=,
|
||||
and --private-key-source= to specify the signing information for as a
|
||||
path or OpenSSL engine or provider.
|
||||
|
||||
* systemd-tmpfiles gained a new option --dry-run to print what would be
|
||||
done without actually taking action.
|
||||
|
||||
* systemd-bsod gained a new option --tty= to specify the output TTY
|
||||
|
||||
* timedatectl and machinectl gained option '-P', an alias for
|
||||
'--value --property=…'.
|
||||
|
||||
* Various tools that pretty-print config files will now highlight
|
||||
configuration directives.
|
||||
|
||||
Libraries:
|
||||
|
||||
* libsystemd gained new call sd_bus_creds_new_from_pidfd to get a
|
||||
credentials object for a pidfd and sd_bus_creds_get_pidfd_dup() to
|
||||
retrieve the pidfd from a credentials object.
|
||||
|
||||
* RPM macro %_kernel_install_dir has been added with the path
|
||||
to the directory for kernel-install plugins.
|
||||
|
||||
Other:
|
||||
|
||||
* systemd-logind now supports a new "background-light" session class
|
||||
which does not pull in the user@.service unit. This is intended in
|
||||
particular for cron jobs.
|
||||
|
||||
systemd-logind now also supports a new "user-incomplete" session
|
||||
class for a user session that does not have a running user manager,
|
||||
but may be upgraded to a full "user" session later on. This has
|
||||
been hooked into the PAM stack to appropriately classify sessions
|
||||
while they are being started.
|
||||
|
||||
systemd-logind gained a new org.freedesktop.login1.Session.SetClass()
|
||||
method to change the session class.
|
||||
|
||||
systemd-logind will not allow background, background-light, manager,
|
||||
and manager-early session types to take control of devices or change
|
||||
the session type.
|
||||
|
||||
* systemd-logind gained a new
|
||||
org.freedesktop.login1.Manager.ListSessionsEx() method that provides
|
||||
additional metadata compared to ListSessions(). loginctl makes use of
|
||||
this to list additional fields in list-sessions.
|
||||
|
||||
* systemd-cryptenroll can now enroll directly with a public key
|
||||
(instead of a certificate).
|
||||
|
||||
* Core dumps are now retained for two weeks by default.
|
||||
|
||||
* systemd-cryptsetup gained support for crypttab option
|
||||
link-volume-key= to enter the volume key into the kernel keyring when
|
||||
the volume is opened.
|
||||
|
||||
* The remaining documentation that was on
|
||||
https://freedesktop.org/wiki/Software/systemd/ has been moved to
|
||||
https://systemd.io.
