Why won't /unix run?

[Dave Sherman]

I'm running v7 on an 11/23 (with 2 RL02's) at the Law Society.
I have been trying to make a new /unix which will work (original
object was to extend NINODE).

Forget about the problems I have in trying to get a *different*
/unix to work. Right now I can't boot from /unix..... but I
*can* boot from /ounix, which is exactly the same! "cmp /unix /ounix"
indicates they're identical. I can boot from /ounix and run a "ps"
which works perfectly looking at /unix. But I can't boot from /unix -
the system just hangs.

Any guesses? (I don't think I have a bad disk block, or I'd get
error messages when accessing /unix from cmp, ps, etc.)
