The dump fills up precisely the entire 'b' partition. Since the
partition begins at offset 0, the dump overwrites the label at sector
offset 1 and any bootblocks at sector offsets 0-15. This misconfiguration
is handled for swapping but not for dumping.
This shouldn't lose any data. Just restore the label from a backup and
write new bootblocks.
