A technical description would be appreciated although the manpage looks like a good start
as does Lions. I hadn't gotten to chapter 20 yet, should have known he would cover
the topic.

Yeah, but I was unsure whether the OP wanted a technical description, or
one in plain English :-) I'm still prepared to do the latter, once I can
find a spare hour.
Somewhere, deep within Minnie's bowels, there might be a paper that I
wrote upon implementing a "bad block" system (specifically directed at the
RK-05, but generally applicable to any device); it involved the hitherto-
unused inode "0", to which were chained the bad blocks (added by hand).
The trick was that normal FS utilities would ignore it...
Someone at the time (Kevin Hill?) pointed out that inode "-1" could also
be used, but I wasn't prepared to go that far :-)
