don't exist yet, and only then the argument string is written to the
file.
* A new environment variable $SYSTEMD_OFFLINE is now understood by
systemctl. It takes a boolean argument. If on, systemctl assumes it
operates on an "offline" OS tree, and will not attempt to talk to the
service manager. Previously, this mode was implicitly enabled if a
chroot() environment was detected, and this new environment variable
now provides explicit control.
* .path and .socket units may now be created transiently,
too. Previously only service, mount, automount and timer units were
supported as transient units. The elogind-run tool has been updated
to expose this new functionality, you may hence use it now to bind
arbitrary commands to path or socket activation on-the-fly from the
command line. Moreover, for the unit types already supporting
transient operation most properties are now hooked up.
* The elogind-mount command gained support for a new --owner= parameter
which takes a user name, which is then resolved and included in uid=
and gid= mount options string of the file system to mount.
* A new unit condition ConditionControlGroupController= has been added
that checks whether a specific cgroup controller is available.
* Unit files, udev's .link files, and elogind-networkd's .netdev and
.network files all gained support for a new condition
ConditionKernelVersion= for checking against specific kernel
versions.
* In elogind-networkd, the [IPVLAN] section in .netdev files gained
support for configuring device flags in the Flags= setting In the
same files, the [Tunnel] section gained support for configuring
AllowLocalRemote=. The [Route] section in .network files gained
support for configuring InitialCongestionWindow=,
InitialAdvertisedReceiveWindow= and QuickAck=. The [DHCP] section now
understands RapidCommit=.
* elogind-networkd's DHCPv6 support gained support for Prefix
Delegation.
* sd-bus gained support for a new "watch-bind" feature. When this
feature is enabled, an sd_bus connection may be set up to connect to
an AF_UNIX socket in the file system as soon as it is created. This
functionality is useful for writing early-boot services that
automatically connect to the system bus as soon as it is started,
without ugly time-based polling. elogind-networkd and
elogind-resolved have been updated to make use of this
functionality. busctl exposes this functionality in a new
--watch-bind= command line switch.
* sd-bus will now optionally synthesize a local "Connected" signal as
soon as a D-Bus connection is set up fully. This message mirrors the
already existing "Disconnected" signal which is synthesized when the
connection is terminated. This signal is generally useful but
particularly handy in combination with the "watch-bind" feature
described above. Synthesizing of this message has to be requested
explicitly through the new API call sd_bus_set_connected_signal(). In
addition a new call sd_bus_is_ready() has been added that checks
wether a connection is fully set up (i.e. between the "Connected" and
"Disconnected" signals).
* sd-bus gained two new calls sd_bus_request_name_async() and
sd_bus_release_name_async() for asynchronously registering bus
names. Similar, there is now sd_bus_add_match_async() for installing
a signal match asynchronously. All of elogind's own services have
been updated to make use of these calls. Doing these operations
asynchronously has two benefits: it reduces the risk of deadlocks in
case of cyclic dependencies between bus services, and it speeds up
service initialization since synchronization points for bus
round-trips are removed.
* sd-bus gained two new calls sd_bus_match_signal() and
sd_bus_match_signal_async(), which are similar to sd_bus_add_match()
and sd_bus_add_match_async() but instead of taking a D-Bus match
string take match fields as normal function parameters.
* sd-bus gained two new calls sd_bus_set_sender() and
sd_bus_message_set_sender() for setting the sender name of outgoing
messages (either for all outgoing messages or for just one specific
one). These calls are only useful in direct connections as on
brokered connections the broker fills in the sender anyway,
overwriting whatever the client filled in.
* sd-event gained a new pseudo-handle that may be specified on all API
calls where an "sd_event*" object is expected: SD_EVENT_DEFAULT. When
used this refers to the default event loop object of the calling
thread. Note however that this does not implicitly allocate one —
which has to be done prior by using sd_event_default(). Similar
sd-bus gained a three new pseudo-handles SD_BUS_DEFAULT,
SD_BUS_DEFAULT_USER, SD_BUS_DEFAULT_SYSTEM that may be used to refer
to the default bus of the specified type of the calling thread. Here
too this does not implicitly allocate bus connection objects, this
has to be done prior with sd_bus_default() and friends.
* sd-event gained a new call pair
sd_event_source_{get|set}_io_fd_own(). This may be used to optionally
automatically close the file descriptor an IO event source watches
when the event source is destroyed.
* elogind-networkd gained support for natively configuring WireGuard
connections.
* Already in previous versions elogind synthesized user records both
for the "nobody" (UID 65534) and "root" (UID 0) users in nss-elogind
and internally. In order to simplify distribution-wide renames of the
"nobody" user (like it is planned in Fedora: nfsnobody → nobody), a
new transitional flag file has been added: if
/etc/elogind/dont-synthesize-nobody exists synthesizing of the 65534
user and group record within the elogind codebase is disabled.
* elogind-notify gained a new --uid= option for selecting the source
user/UID to use for notification messages sent to the service
manager.
* There's now a "elogind-analyze service-watchdogs" command for turning
on or off the per-service watchdogs system-wide (i.e. the concept you
configure in WatchdogSec=), for debugging purposes. There's also a
kernel command line option elogind.service_watchdogs= for controlling
the same.
