CHANGES WITH 229:
* Creation of the legacy /run/lock/lockdev/ directory was
dropped from tmpfiles.d/legacy.conf. Hardly any software uses
that any more, and better locking mechanisms like flock() have
* The systemd-resolved DNS resolver service has gained a substantial
set of new features, most prominently it may now act as a DNSSEC
validating stub resolver. DNSSEC mode is currently turned off by
default, but it is expected that this is turned on by default in one
of the next releases. For now, we invite everybody to test the DNSSEC
logic by setting DNSSEC=allow-downgrade in
/etc/systemd/resolved.conf. The service also gained a full set of
D-Bus interfaces, including calls to configure DNS and DNSSEC
settings per link (for consumption by external network management
software). systemd-resolved (and systemd-networkd along with it) now
know to distinguish between "search" and "routing" domains. The
former are used to qualify single-label names, the latter are purely
used for routing lookups within certain domains to specific
links. resolved will now also synthesize RRs for all entries from
/etc/hosts.
* The systemd-resolve tool (which is a client utility for
systemd-resolved, and previously experimental) has been beefed up
considerably and is now fully supported and documented. It has moved
from /usr/lib/systemd to /usr/bin because.
* /dev/disk/by-path/ symlink support has been (re-)added for virtio
devices.
* The systemd-activate socket activation testing tool gained support
for SOCK_DGRAM and SOCK_SEQPACKET sockets using the new --datagram
and --seqpacket switches. It also has been extended to support both
new-style and inetd-style file descriptor passing. Use the new
--inetd switch to request inetd-style file descriptor passing.
* Most systemd tools now honour a new $SYSTEMD_COLORS environment
variable, which takes a boolean value. If set to false ANSI color
output is disabled in the tools even when run on a terminal that
supports it.
* The VXLAN support in networkd now supports two new settings
DestinationPort= and PortRange=.
* A new systemd.machine_id= kernel command line switch has been added,
that may be used to set the machine ID in /etc/machine-id if it is
not initialized yet. This command line option has no effect if the
file is already initialized.
* systemd-nspawn gained a new --as-pid2 switch that invokes any
specified command line as PID 2 rather than PID 1 in the
container. In this mode PID 1 will be a minimal stub init process
that implements the special POSIX and Linux semantics of PID 1
regarding signal and child process management. Note that this stub
init process is implemented in nspawn itself and requires no support
from the container image. This new logic is useful to support running
arbitrary command lines in the container, as normal processes are
generally not prepared to run as PID 1.
* systemd-nspawn gained a new --chdir= switch for setting the current
working directory for the process started in the container.
* "journalctl /dev/sda" will now output all kernel log messages from
the specified device, in addition to all devices that are parents of
it. This should make log output about devices pretty useful, as long
as kernel drivers attach enough metadata to the log messages. (The
usual SATA drivers do.)
* The sd-journal API gained two new calls
sd_journal_has_runtime_files() and sd_journal_has_persistent_files()
that report whether log data from /run or /var has been found.
* journalctl gained a new switch "--fields" that prints all journal
record field names currently in use in the journal. This is backed
by two new sd-journal API calls sd_journal_enumerate_fields() and
sd_journal_restart_fields().
* Most configurable timeouts in systemd now expect an argument of
"infinity" to turn them off, instead of "0" as before. This follows
of a logic where a timeout of "0" means "now", and one of "infinity"
means "never". For compatibility where this was supported before 0
continues to be accepted to turn off timeouts.
* "systemctl reload-or-try-restart" has been renamed to "systemctl
try-reload-or-restart" to make clearer what it actually does, and
indicate that the "try" logic applies to both reloading and
restarting and not just restarting. The old name continues to be
accepted for compatibility.
* On boot-up when PID 1 detects that the system clock is before the
release date of the systemd version in use, the clock is now bumped
ahead to it. Previously, this was already done in timesyncd, in order
to avoid running with clocks set to the various clock epochs such as
1902, 1938 or 1970. With this change the logic is now done in PID 1
in addition to timesyncd during early boot-up, so that it is enforced
before the first process is spawned by systemd. Note that the logic
in timesyncd remains, as it is more comprehensive and ensures
montonic clocks by maintaining a persistant timestamp file in
/var. Since /var is generally not available in earliest boot or the
initrd, this part of the logic remains in timesyncd, and is not done
by PID 1.
* A new service setting RuntimeMaxSec= has been added that may be used
to specify a maximum runtime for a service. If the timeout is hit the
service is terminated and put into a failure state.
* A new service setting AmbientCapabilities= has been added, that
allows configuration of additional Linux process capabilities that
are passed to the activated processes. This is only available on very
recent kernels.
* The process resource limit settings in service units may now be used
to configure hard and soft limits individually.
* The various libsystemd APIs such as sd-bus or sd-event now publically
expose support for gcc's __attribute__((cleanup())) C
extension. Specifically, for many object destructor functions
alternative versions whose names are suffixed with "p" and take a
pointer to a pointer to the object to destroy instead of just a
pointer to the object itself have been added. This is useful because
these destructor functions may be used directly as parameters to the
cleanup construct. Internally, systemd has been a heavy user of the
GCC extension since a long time, and with this change similar support
is now available to consumers of the library outside of systemd. Note
of course, that by using this extension in your sources compatibility
with old and strictly ANSI compatible C compilers is lost. However,
any gcc or LLVM version of the last years has been supporting this
extension just fine.
* Timer units gained support for a new setting RandomizedDelaySec= that
allows configuring an amount of additional randomized delay to add
to the time a timer elapses. This is useful to distribute timer
events over a time range to avoid load peaks in clusters or larger
setups.
* Calendar time specifications now support sub-second accuracy.
* Socket units now support listening on SCTP and UDP-lite protocol
sockets.
* The sd-event API now comes with a full set of man pages.
* Older versions of systemd contained experimental support for
compressing journal files and coredumps with the LZ4 compressor that
was not compatible with the lz4 binary (due to API limitations of the
lz4 library). This support has been removed; only support for files
compatible with the lz4 binary remains. This LZ4 logic is now
officially supported and no longer considered experimental.
* The dkr image import logic has been removed again from importd. dkr's
micro-services focus doesn't fit into the machine image focus of
importd, and quickly got out of date with the upstream dkr API.
* Creation of the /run/lock/lockdev/ directory was dropped from
tmpfiles.d/legacy.conf. Better locking mechanisms like flock() have
been available for many years. If you still need this, you need to
create your own tmpfiles.d config file with:
d /run/lock/lockdev 0775 root lock -
d /run/lock/lockdev 0775 root lock -
