I do not know why Arno does this, but on my system (ARM Kirkwood,
linux-2.6.36, ubifs) I see messages "UBIFS: recovery needed" when
doing a reboot without manually mounting the filesystem(s) read-only
before.

So there seem to be setups where the normal reboot does not force
a sane filesystem state on all attached filesystems, although
unfortunately I did not yet have time to figure out what exactly
is happening there.
