Well, a broken light would be excusable, although I don't have a good
equivalent in a file system :-))

It's a live structure, so you'd have to periodically update it - not
that you couldn't use an older copy, too. And I really don't know why
BFS doesn't do this - after my super blocks got overwritten, I have
hoped it had done it.
One possible reason could be that if the super block is corrupt, there
is likely to be other failures, too, so why bothering? (from a file
system perspective).
Adios...
Axel.
