On a old decstation 3100 I was deleting last semesters users to try to dig up some disk space, I also deleted some test users at the same time.
One user took longer then usual, so I hit control-c and tried ls.
"ls: command not found"
Turns out that the test user had / as the home directory and the remove user script in ultrix just happily blew away the whole disk. ftp, telnet, rcp, rsh, etc were all gone. Had to go to tapes, and had one LONG rebuild of X11R5.
