For the mentioned appliances, that would not be a problem.
However there's a distinction between /tmp and /var/tmp
that can be summarized like this: The content of /tmp may
disappear after a reboot (see clear_tmp_enable="YES" in
/etc/rc.conf), whereas /var/tmp is to be preserved during
reboot. Some programs rely on this behavior when putting
"delete-temporary" and "keep-temporary" files into the
respective directories.
