Public bug reported:
I rebooted my laptop after a crash.
Fsck couldn't repair the /var partition, so I was greeted with "Welcome
to Emergency!" and the request to look at `journalctl -xb`.
After logging in, and journalctl telling me about the broken /var
partition, I tried
fsck /dev/mapper/vg0-var
which immediately returned with a message stating that /dev/mapper/vg0-var is
busy.
Looking at the processes with `ps aux | grep fsck` gave
- systemd-fsckd
- /sbin/fsck /dev/mapper/vg0-var
- fsck.ext2 /dev/mapper/vg0-var
Trying to kill `fsck.ext2` or `fsck` was futile, because `fsck` was
dying and restarting faster, than I could look at the process list.
Killing `systemd-fsckd` finally ended the busy loop.
But still, I couldn't check my /var partition, because now systemd has
mounted my /var partition, even though it told me before, it was in need
of repair.
After unmounting /var, I could finally do the much needed `fsck
/dev/mapper/vg0-var`.

I would expect
1. systemd-fsck stop restarting fsck, when it was aware, that it must be
checked manually
2. systemd *not* mount an unchecked file system, especially when systemd-fsckd
stopped with an error or was killed
