I wonder what Reeds meant. I know there are issues. For example, the 3B2 I
administered for a while in the late 80s had multiple accounts with rsh,
the restricted shell, as the login shell. That was okay, unless you used su
and then had access to a root shell.

HP/UX was way worse, with over 120 SUID shell scripts in the 90s. A much
more interesting example of insecurity. But somehow, I'm guessing that's
not what Reeds wrote about.
