Bug#470956: initscripts: checkroot.sh shouldn't fsck twice with /forcefsck

[Pierre Ynard]

Oh sorry, I hadn't fully realized that as indicated by the title, this
was with /forcefsck set. In that case, as I said, since the filesystem
is still read-only, the /forcefsck flag can't be cleared - nor should
it be cleared at this point, because it covers all mounts and not just
root.

So an alternative interface to creating a /forcefsck file would have to
be used, one that doesn't reside on the filesystem itself and can be set
and cleared for individual filesystems separately - for example, the
filesystem internal data.
