A non-trivial amount of cool new features, but primarily bug fixes bug
fixes bug fixes.
Note that I intend to make this the final version we push into Fedora
18. systemd 196 will be the first release we commit to Fedora 19. This
might or might not be a good idea for other distros to keep in mind, if
you guys need something stabilized. From now we'll just backport
cherry-picked fixes to F18, the way this is done for F17. So it might be
cool to watch our F18 packaging repo.
Oh, and one more thing. In Fedora I added
"cap_dac_override,cap_sys_ptrace+ep" as file capabilities to
/usr/bin/systemd-detect-virt, so that this useful tool works for
unprivileged users too. (Yeah, cap_sys_ptrace sounds crazy, but Linux
sucks, it's required to read a few things off /proc/1/). The systemd
makefile will do the same, but if you package systemd for your distro
with RPM or suchlike you probably need to declare this explicitly in
your spec file. Note that not adding these caps is not a problem, you'll
just get a clean permission error if you run it as non-privileged
user. Also nothing depends on this being run as unprivileged user that I
was aware of, so this is really just about making a useful tool more
widely available, and not really a dependency for anything.
* journalctl gained the new --since= and --until= switches to
filter by time. It also now supports nice filtering for
units via --unit=/-u.
* Type=oneshot services not may use ExecReload= and do the
* The journal daemon now supports time-based rotation and
vacuuming, in addition to the usual disk-space based
* The journal will now index the available field values for
each field name. This enables clients to show pretty drop
downs of available match values when filtering. The bash
completion of journalctl has been updated
accordingly. journalctl gained a new switch -F to list all
values a certain field takes in the journal database.
* More service events are now written as structured messages
to the journal, and made recognizable via message IDs.
* The timedated, localed and hostnamed mini-services which
previously only provided support for changing time, locale
and hostname settings from graphical DEs such as GNOME now
also have a minimal (but very useful) text-based client
utility each. This is probably the nicest way to changing
these settings from the command line now, especially since
it lists available options and is fully integrated with bash
* There's now a new tool "systemd-coredumpctl" to list and
extract coredumps from the journal.
* We now install a README each in /var/log/ and
/etc/rc.d/init.d explaining where the system logs and init
scripts went. This hopefully should help folks who go to
that dirs and look into the otherwise now empty void and
scratch their heads.
* When user-services are invoked (by systemd --user) the
$MANAGERPID env var is set to the PID of systemd.
* SIGRTMIN+24 when sent to a --user instance will now result
in immediate termination of systemd.
* gatewayd received numerous feature additions such as a
"follow" mode, for live syncing and filtering.
* browse.html now allows filtering and showing detailed
information on specific entries. Keyboard navigation and
mouse screen support has been added.
* gatewayd/journalctl now supports HTML5/JSON
Server-Sent-Events as output.
* The SysV init script compatibility logic will now
heuristically determine whether a script supports the
"reload" verb, and only then make this available as
* "systemctl status --follow" has been removed, use "journal
* journald.conf's RuntimeMinSize=, PersistentMinSize= settings
have been removed since they are hardly useful to be
* And I'd like to take the opportunity to specifically mention
Zbigniew for his great contributions. Zbigniew, you rock!
