. also implement now-possible fsck -p option
. allows unconditional fsck -p invocation at startup,
only checking each filesystem if not marked clean
. mounting unclean is allowed but is forced readonly
. updating the superblock while mounted is now not
allowed by mfs - must be done (e.g. by fsck.mfs)
on an unmounted fs
. clean flag is unset by mfs on mounting, and set by
mfs on clean unmounting (if clean flag was set at
mount time)
