It seems we found a bug in HP-UX yesterday. I'm not sure, because we
don't want to try it again.

Our configuration consists of one HP9000/350 with a few disks, and a
couple of diskless machines of the same kind. "uname -a" says:
	HP-UX coca 7.0P0826 B 9000/350 coca

For a certain reason, we wanted to know what error message the 'rmdir'
command would give us when told to remove a non-empty directory, so,
being non-root, and therefore not risking anything, logged in on one
of the diskless machines, we did

	rmdir /

The server panicked. And of course all the diskless ones followed it.
I know I should have written down the panic message, but I forgot.

(To increase the probability of this happening, if you try it yourself,
you may want to make sure someone is saving a whole day's valuable
work at the precise time you do this.)
