Careful with the order of those commands.  You are *NOT* allowed to fsck
a filesystem that has been mounted as read-write.  You also missed an
invocation of adjkerntz, which is pretty much mandatory for getting the
timestamps of files right.

The correct thing to do, would be (comments in parentheses):

        # adjkerntz -i			(adjust kernel time)
	# fsck -p			(check all filesystems)
	# mount -u /			(mount root fs as read-write)
	# mount -a			(mount all other filesystems)
