Here's a fun story. The machine rodan.uu.net is the central server
for internal stuff at UUNET; it's where staff gets their email,
has their homedirs, etc. Well for some reason there was a file
/usr/spool/mqueue/=sendmail file, but no /usr/lib/sendmail.
Someone cp'd the latter, and tried to remove the former
rm =sendmail
Well, in zsh "=foo" means "expand to the full path of the exectuable of foo.
Zap, away went /usr/lib/sendmail AGAIN and nobody at uunet got email for
an hour or two.
Two iterations of this.
