It should be /var/tmp. It's bad enough that some bozo created two
standard locations for temporary files (/tmp and /var/tmp), we don't
want to add a third.
Frankly, it makes no sense to have more then one. In every machine
I've ever configured for the last umpteen years I've created a /var/tmp
partition and softlinked /tmp to it. Programs make no real distinction
in functionality except perhaps a couple of minor ones in our tree.
You wind up having to put tonnes of space in both anyway so they might
as well be the same. It just doesn't make any sense to separate them
out nor does it make sense to introduce yet another 'standard' location
for tmp.
The cron job should generally just use a find -mtime ... -delete for
/tmp rather then attempt to wipe it entirely. There should be no
distinction in functionality.
So it should be /var/tmp with /tmp a softlink. Works just dandy even
in single-user mode (you create a degenerate /var/tmp in / so you get
a working tmp even if /var is not mounted).
