I did too (chucking in some extra "/sbin/fsck -b 32" type lines into the
top of /etc/rc blew up on me).  And you can't rely on it being at block 32,
e.g. some of mine were at block 64 for FFSs with other size blocks & frags.

: Is there any way to either get the kernel to fix this for you during

Seconded.
