A good rule of thumb for any situation where a filesystem format is changing
is to zero out the first 64 blocks of the partition with `dd'.
With all the times I've hit a fs "oops" situation, I find that rule so
useful that it might be worthwhile to make it part of sysinst when a
partition is marked for newfs'ing. 8-)
