[systemd-devel] systemd 256 released
A new, official systemd release has just been tagged . Please download
the tarball here:
https://github.com/systemd/systemd/archive/v256.tar.gz
Changes since the previous release:
Announcements of Future Feature Removals and Incompatible Changes:
* Support for automatic flushing of the nscd user/group database caches
will be dropped in a future release.
* 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.
* Support for System V service scripts is deprecated and will be
removed in a future release. Please make sure to update your software
*now* to include a native systemd unit file instead of a legacy
System V script to retain compatibility with future systemd releases.
* Support for the SystemdOptions EFI variable is deprecated.
'bootctl systemd-efi-options' will emit a warning when used. It seems
that this feature is little-used and it is better to use alternative
approaches like credentials and confexts. The plan is to drop support
altogether at a later point, but this might be revisited based on
user feedback.
* systemd-run's switch --expand-environment= which currently is disabled
by default when combined with --scope, will be changed in a future
release to be enabled by default.
* Previously, systemd-networkd did not explicitly remove any bridge
VLAN IDs assigned on bridge master and ports. Since version 256, if a
.network file for an interface has at least one valid setting in the
[BridgeVLAN] section, then all assigned VLAN IDs on the interface
that are not configured in the .network file are removed.
* IPForward= setting in .network file is deprecated and replaced with
IPv4Forwarding= and IPv6Forwarding= settings. These new settings are
supported both in .network file and networkd.conf. If specified in a
.network file, they control corresponding per-link settings. If
specified in networkd.conf, they control corresponding global
settings. Note, previously IPv6SendRA= and IPMasquerade= implied
IPForward=, but now they imply the new per-link settings. One of the
simplest ways to migrate configurations, that worked as a router with
the previous version, is enabling both IPv4Forwarding= and
IPv6Forwarding= in networkd.conf. See systemd.network(5) and
networkd.conf(5) for more details.
* systemd-gpt-auto-generator will stop generating units for ESP or
XBOOTLDR partitions if it finds mount entries for or below the /boot/
or /efi/ hierarchies in /etc/fstab. This is to prevent the generator
from interfering with systems where the ESP is explicitly configured
to be mounted at some path, for example /boot/efi/ (this type of
setup is obsolete, but still commonly found).
* The behavior of systemd-sleep and systemd-homed has been updated to
freeze user sessions when entering the various sleep modes or when
locking a homed-managed home area. This is known to cause issues with
the proprietary NVIDIA drivers. Packagers of the NVIDIA proprietary
drivers may want to add drop-in configuration files that set
SYSTEMD_SLEEP_FREEZE_USER_SESSIONS=false for systemd-suspend.service
and related services, and SYSTEMD_HOME_LOCK_FREEZE_SESSION=false for
systemd-homed.service.
* systemd-tmpfiles and systemd-sysusers, when given a relative
configuration file 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/ configuration 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 the combination of 'R /foo' and 'x
/foo/bar', /foo/bar will now be excluded from removal.
* systemd.crash_reboot and related settings are deprecated in favor of
systemd.crash_action=.
General Changes and New Features:
* Various programs will now attempt to load the main configuration file
