The issue Curt talks about is "old fsck compares too many superblock
fields and incorrectly signals a bad superblock". The only thing you
can do about that is install a new fsck. 1.6.1 has a forward compat
patch, so that a 1.6.1 -> 2.0 upgrade will not have this problem.
The Apple UFS problem looks to be something else.
