Bad blocks?  I think I have an article in AUUGN where I proposed that bad 
blocks be assigned (somehow) to a pseudo-file as inode #0 (or -1?); that 
way, the "dump" utility would not see it, and neither would the FS tools 
(but a disk image would, of course).

Odd layout...  I normally saw them the other way around.
