That is generally true, but also "hard" as we don't have a handle on the OS.

While that was a very helpful post yet it may only apply to Arch Linux as
stated. My Ubuntu systems at home and work all run systemd too, but do _not_
automatically remove tempfiles.
Yet what he suggested is quite right: we should define a proper config file
for this facility and then possibly also use the /run directory as many other
services now and (of course) also either TEMPDIR or later the code to have
/run be another fallback if TMP, TEMP, TMPDIR, ... are unset.
