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)
