Hi, David, I'm sorry, yes, you're right!  Wasn't thinking that far...

Nope, I'm thinking disklabels (I know about superblocks).  Under Solaris,
try it sometime.  Write a disklabel out to disk, and then skrog the first
instance of it at the beginning of the disk.

Now, when you run format, it will try to find the disklabel.  Failing that,
it will try to find a backup disklabel (it will also do this if you run
the "backup" command in format).
