Hi,
this wouldn't really work, since there would be regular windows
where the directory would be missing. tmpwatch configuration
should instead be tweaked to ignore /tmp/systemd-private-* and
/var/tmp/systemd-private-*.

Recently (>197) there have been changes to systemd-tmpfiles to
leave those directories in place. Michal Sekletar recently posted
a patch to make systemd clean then up properly by itself.
