Didn't Robert Tappin Morris point this out to NSA people when he did his
Simple: Fill up /var/tmp, and the system can't log your breakin.

Hmmm, I'd be pretty upset if I was in the middle of something at some odd
hour, like high noon or 4 in the morning, and /tmp went away.
I wouldn't want /var/tmp/vi.recover to go away, that would be bad. I usually
make a separate partition for /var, and one for /var/tmp. No, it isn't the
most efficient use of drive space, but it means Joeuser@localhost can't
cut off my logging ability.
The NCSU machines have swap mounted on /tmp. They get cleaned when the user
logs out of the machine (single user per machine). Course,
/var/spool/uucppublic doesn't get cleaned (heh heh heh), and neither does
/var/mail (c'mon, 8mb isn't enough quota, right?)
