/* its alot cleaner now, and adding support for new partition types

isn't a bitch anymore
|
|
known bugs:
|
|
1) when only an HFS part exists on a drive it gets assigned to "B"
|
|
this is because of line 623 of sd.c, I think this line should go.
|
|
2) /sbin/disklabel expects the whole disk to be in "D", we put it in
|
|
"C" (I think) and we don't set that position in the disklabel structure
|
|
as used. Again, not my fault.

NetBSD to live on cluster 0--regardless of the actual order on the
