Ahha - of course. Ok, let me re-phrase the question then. By looking at the contents of the superblocks on a UFS file system it's possible to reconstruct a disklabel for a slice. Is this trick possible with other kinds of file systems too? (Does it even make sense to ask that question?). Should this recovery functionality be part of an already existing tool, like disklabel, or should it be a completely new tool? Opinions? Would it be possible to tag swap partitions with an equivalent of a superblock to make their recognition easier under failure conditions?
