Here'a a first crack at it:

Any suggestions for improvements/additions will be gratefully received!


I've also been amusing myself trying to figure out who wrote:

  http://ana-3.lcs.mit.edu/~jnc/tech/unix/s1/fcheck.c

and how it got to MIT - which might give us a clue as to who wrote it. (It's
clearly a distant ancestor to 'fsck'.) The fact that we've lost Ted Kowalski
is really hindering, alas. Interestingly, Dale DeJager, head of the CB-UNIX
group, earlier remembered Hal Pierson working on a file system checker early
on:

  "Hal also implemented the first file system check routine that was written
  in C. It replaced an .. assembler version from research"

but it's not clear if the thing Hal wrote, mentioned there, has any
relationship with the 'check' of V5:

  https://minnie.tuhs.org/cgi-bin/utree.pl?file=V5/usr/source/s1/check.c

Maybe one of the Labs old-timers here remembers where the V5 thing came from?
(I.e. did Ken or Dennis write it, or did it come from Columbus?) If you do, it
would be a big help!
