I've been playing recently with systemd on Arch, and had much fun. But
soon, alas, my fingers started to ache from repeatedly writing
systemctl restart some-long-service.service. So, I wrote a completion
script. I figured other people may want to use it, so I prepared a
patch against systemd-git (attached).
There are some notes/disclaimers, however:
- It requires bash>=4.0, sed, grep and awk. A bash-completion package
is not strictly needed; sourcing the file is enough.
- It wouldn't work properly with --session, as I had no way to test it.
- It uses the output of systemctl list-units directly when that's
enough, but also runs systemctl show when completing on some verbs
(for example, to check for AllowIsolate=yes). This /may/ be somewhat
slow once there are many units, since it calls a dbus method on each
one. Is there a faster way to have that information?
- The code is perhaps a bit long and messy; honestly, I blame the tool ;)
One way to improve on the situation is to integrate some completion
code in systemctl itself, the way e.g. gdbus, gsettings and django do
it. This will allow for finer grained and faster completions, and it
won't be necessary to keep the verb/option tables in sync with some
other file. But it does mean adding all of this code in C. If this is
acceptable, I'll try to have a go at it.
Finally, a couple of completion tips I run into:
- If you alias systemctl to, say, sctl, you get completions on that
too by running to following command:
complete -F _systemctl sctl
- Add the following line to your .inputrc, to have the completion show
after only a single tab press:
set show-all-if-ambiguous on
It makes the shell quite more pleasant.
Hope it's good enough!
Ran
Initial commit of a tmpfiles.d manpage.
I ran it through xmllint but I don't know how to make it look pretty
like the rest of the xml files. :-P

1) Just ship rc-local as-is; don't worry about the 'local' name.
2) Don't install rc-local and prefdm to /etc ; just enable them globally for the system in /lib.
Previously Ubuntu was treated as being equivalent to Debian, but the two
distributions require different behaviour in certain places. This commit does
not change the behaviour of systemd on either distro but it creates a
framework for changes to be introduced by later commits.
The following previously meant "Target is Debian or Ubuntu".
* configure option "--with-distro=debian"
* C preprocessor symbol "TARGET_DEBIAN"
* Automake conditional "TARGET_DEBIAN"
After this commit, all of the above are redefined to mean "Target is Debian"
The following are introduced to mean "Target is Ubuntu".
* configure option "--with-distro=ubuntu"
* C preprocessor symbol "TARGET_UBUNTU"
* Automake conditional "TARGET_UBUNTU"
Most code written for Debian will also be applicable to Ubuntu. An extra
Automake conditional "TARGET_DEBIAN_OR_UBUNTU" is introduced to avoid
duplication of code that would otherwise occur.
This commit updates configure.ac, Makefile.am and distro-specific source files
in line with the above definitions.
This functions are working as follows:
- Send a SIGTERM to all processes that may be finished
- Send a SIGKILL to all processes that still live and may be finished
- Try to unmount all mount points
- Try to remount read-only all mount points that can't be umounted
- Umount all swap devices
- Umount and detach all loopback devices
- Call [poweroff|halt|reboot|kexec]
TODO:
- Umount device-mapper.
- Make log work. So far it is being useless as we do not parse
/etc/systemd/system.conf, kernel command line but just
environment, however we're executed by init and thus have no
useful variables. Forcing it to target=kmsg/console and
level=debug also does not produce any output, however writing to
/dev/console does work (hack used during debug).
Arch uses the same paths and default font of gentoo. Previously,
systemd-vconsole-setup was failing with the following message:
systemd-vconsole-setup[59]: /bin/setfont failed with error code 1.
This patch is a bit bigger than expected since Gentoo being
non-standard in some places.
1. it is installing binaries at /usr/bin instead of /bin.
2. it is using CamelCase names for consolefonts.
3. /etc/rc.conf:unicode=(yes|no) just forbids loadkeys and setfont
"-u" options, but do not disable the actual kernel default_utf8
from vt module.
Add unit files to call
/etc/init.d/umountnfs.sh stop (network file systems)
/etc/init.d/umountfs stop (local file systems)
/etc/init.d/umountroot stop ("/" file system)
in the right order and hook them up in the umount.target so they are run
on shutdown and reboot.
On Debian sysinit is not a single script but a separate runlevel.
Split of fsck.target into separate unit file as otherwise we get an
unbreakable cycle on shutdown/reboot.
It is essential that the gettys are proper dependencies from
getty.target so that they aren't killed and immediately restarted on
runlevel changes. Hence rework the logic to implicitly add console
gettys to getty.target as dependencies.
This also adds an automatic hvc console for virtualizers.

In order to unify configuration across distributions we pick the
simple-most option by default (Debian's /etc/hostname) and then fall
back to distro-specific hacks if that doesn't exist.
It seems to work on my machine.
/proc/1/fd/20 system_u:system_r:system_dbusd_t:s0
/proc/1/fd/21 system_u:system_r:avahi_t:s0
And the AVC's seem to have dissapeared when a confined app trys to
connect to dbus or avahi.
If you run with this patch and selinux-policy-3.8.8-3.fc14.noarch
You should be able to boot in enforcing mode.
Rename --start to --realize, to make things less confusing when doing
"systemctl stop --realize foo.service".
Introduce --realize=reload.
Don't talk to systemd when run within a chroot, or when systemd isn't
running.
