I disagree about this. There's no more reason to "clean up" (meaning,
really, stomp about destroying things in) /tmp than there is anywhere
else. Much of the system depends on having /tmp (/var/tmp, /usr/tmp,
whatever) available, but the only failure mode the automated "cleanup"
script can fix is being out of disk space, and if that happens to /tmp
it needs attention more immediate than daily can provide. (Well, on
most systems, and on the rest it can wait for a human even if it takes
longer than day.)
One can argue that what's there is a reasonable default, and that
admins can change it - but that applies to everything there; indeed, on
my system the daily/weekly/monthly scripts are not run at all.
