This did not really work out as we had hoped. Trying to do this upstream introduced several problems that probably makes it better suited as a downstream patch after all. At any rate, it is not releaseable in the current state, so we at least need to revert this before the release. * by adjusting the path to binaries, but not do the same thing to the search path we end up with inconsistent man-pages. Adjusting the search path too would be quite messy, and it is not at all obvious that this is worth the effort, but at any rate it would have to be done before we could ship this. * this means that distributed man-pages does not make sense as they depend on config options, and for better or worse we are still distributing man pages, so that is something that definitely needs sorting out before we could ship with this patch. * we have long held that split-usr is only minimally supported in order to boot, and something we hope will eventually go away. So before we start adding even more magic/effort in order to make this work nicely, we should probably question if it makes sense at all.

<title>Description</title>
|
|
|
|
<para><filename>systemd-fsck@.service</filename> and
|
|
<filename>systemd-fsck-root.service</filename> are services
|
|
responsible for file system checks. They are instantiated for each
|
|
device that is configured for file system checking.
|
|
<filename>systemd-fsck-root.service</filename> is responsible for
|
|
file system checks on the root file system, but in only if the
|
|
root filesystem wasn't checked in the initramfs.
|
|
<filename>systemd-fsck@.service</filename> is used for all other
|
|
file systems and for the root file system in the initramfs.</para>
|
|
|
|
<para>Those services are started at boot if
|
|
<option>passno</option> in <filename>/etc/fstab</filename> for the
|
|
file system is set to a value greater than zero. The file system
|
|
check for root is performed before the other file systems. Other
|
|
file systems may be checked in parallel, except when they are one
|
|
the same rotating disk.</para>
|
|
|
|
<para><filename>systemd-fsck</filename> does not know any details
|
|
about specific filesystems, and simply executes file system
|
|
checkers specific to each filesystem type
|
|
(<filename>/sbin/fsck.*</filename>). This helper will decide if
|
|
the filesystem should actually be checked based on the time since
|
|
last check, number of mounts, unclean unmount, etc.</para>
|
|
|
|
<para>If a file system check fails for a service without
|
|
<option>nofail</option>, emergency mode is activated, by isolating
|
|
to <filename>emergency.target</filename>.</para>
