When a service exits succesfully and has RemainAfterExit set, its hold
on the console (in m->n_on_console) wasn't released since the unit state
didn't change.
This allows the user to disable fsck's by masking.
If fsck fails, emergency target is started, the user might mount the
unit using mount and disable fsck by masking the unit. In this case,
.mount will be active because the mount is detect through
/proc/self/mountinfo, but systemd-fsck@.service will still be in
failed mode. This results in a funny situation where
$ systemctl show -p ActiveState local-fs.target yyy.mount
ActiveState=active
ActiveState=active
$ sudo systemctl start local-fs.target
[sudo] password for test:
Failed to start local-fs.target: Unit systemd-fsck@xxx.service is masked.
If fstab contains 1 for passno, treat this as an error, but only warn
briefly. If fstab doesn't contain this information, don't complain at
all.
Patch is complicated a bit by the fact that we might have the fstype specified
in fstab or on /proc/cmdline, in which case we can check if we have the appropriate
fsck tool, or not specified, or specified as auto, in which case we have to look
and check the type of the filesystem ourselves. It cannot be done before the
device appears, so it is too early in the generator phase, and it must be done
directly in fsck service.
Since 31a7eb86 the output on console can be disabled to avoid colliding with
gettys. However, it could also lead to a lack of messages during
shutdown/reboot.
When resolving /dev/console one would often get "tty0" meaning the active VT.
Resolving to the actual tty (e.g. "tty1") will notably help on boot when
determining whether or not PID1 can output to the console.
If the session fifo is not created the session state written to
the session file is "closing". This caused the lock screen in
gnome-shell to go into a loop trying to find the active session.
The problem was introduced in the sd-bus port in
cc37738108

This allows make rules for generated build files (i.e. configure,
Makefile.in, ... ) to be skipped. This is useful when
the source is stored without timestamps (for example in CVS or GIT).
When the build rules trigger to regenerate the build files, it tries to
use the same autotools version (currently 1.14) as was originally used
for the release. Since many of our build machines run Debian Squeeze,
they only have autotools 1.11 available and the build fails.
Currently, we have to work around this by touching all the generated
files before building to avoid triggering the make rule. With this
patch, we would be able to just run configure with
--disable-maintainer-mode instead. The patch sets the default to enable
to not change the default behavior.
