We should not handle the ignore list as API mounts, as
systemd itself never touches them.

At least Mandriva offers configuring characters to toggle
keyboard layout independently from main keymap. This functions
much the same as XkbOptions for X11 and actually is configured
together. The patch adds support for additional keymap,
KEYMAP_TOGGLE, to /etc/vconsole.conf, that is intended to be
used for the same purpose.
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!

Systemd was unconditionally replacing all tags with own.
The net effect was udev-acl tag was lost and devices were
not given proper ACLs, making them inaccessible.

The '-l' option is already taken by fsck.ext[234]:
"-l bad_blocks_file Add to badblocks list"
This reverts commit cf1a105550 but keeps
the string changes.
The property StopRetroactively= needs to be per-dependency, not
per-unit, in order to properly express dependencies between .mount units
and its .device and fsck .service units. If the .device unit is
unplugged the mount should go away, but if the fsck process terminates
the .mount should stay.
If IPv6 is loaded with disable=1, any IPv6 functionality is completely
disabled until the ipv6 module is reloaded. Do not assume IPv6 is available just
because the module is present. Fixes startup error:

Increment n_failed in mount_points_list_umount() if we skip /.
Otherwise it can happen that mount_points_list_remount_read_only() is
not called in umount_all().
The approved method for determining the installed release of
Ubuntu is to execute "lsb_release". However, this is in /usr/bin and
is implemented in python so it is not safe to execute at this early
stage of booting. This code parses /etc/lsb-release which is
where "lsb_release" looks for the information.
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).
This functions will:
- umount all mount points that aren't API
- remount read-only all mount points that can't be umounted
- umount all swap devices.
- detach all loopback devices
TODO:
- umount dms
Mountpoints are being read from /proc/self/mountinfo.
Swaps are being read from /proc/swaps.
Loop devices from /sys/class/block/loop*.
The current behavior of the /proc/self/mountinfo parser
is to stop the parser on parse failures
I'm only changing this behavior to try the next line and adding
a warning if occurs a fail.
This patch adds a cpp definition HAVE_SYSV_COMPAT that is used to
isolate code dealing with /etc/init.d and /etc/rcN.d for systems where
it does not make sense (one that does not use sysv or one that is fully
systemd native).
The patch tries to be as little intrusive as possible, however in
order to minimize the number of #ifdef'ed regions I've reordered some
code in path-lookup.c:lookup_paths_init() where all code dealing with
sysv is now isolated under running_as == MANAGER_SYSTEM as well.
Moreover, In struct Service, some fields were rearranged to reduce
the number of ifdefs.
Lennart's suggestions were fixed and squashed with the original patch,
that was sent by Gustavo Sverzut Barbieri (barbieri@profusion.mobi).
Arch does not use proper SysV runlevels. Instead /etc/rc.conf contains
an array of daemons to load in a multi-user runlevel, and some
dependencies between them.
This patch enables this behaviour in SystemD (only when compiled with
Arch support), which allows SystemD to be a drop in replacement on Arch
(modulo some minor bugs).
v2: simplified after suggestion from Lennart
This patch introduces socket_ipv6_is_supported() call that checks for
IPv6 availability. Code then check for it before using specific calls.
In order to be less intrusive, this patch avoids IPv6 entries being
parsed at all, this way we don't get such entries in the system and
all other code paths are automatically ignored. However an extra check
is done at socket_address_listen() to make sure of that.
As the number of Netlink messages is not know upfront anymore,
loopback-setup.c was refactored to dynamically calculate the sequence
number and count.
Lennart's suggestions were fixed and squashed with the original patch,
that was sent by Gustavo Sverzut Barbieri (barbieri@profusion.mobi).
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.
