Yes. What I was trying to say was: set TMPDIR for many operations,
but file managers, such as mc, should be patched to apply heuristics
to determine whether to use /tmp or /var/tmp.

I think there is, but may be confusing with BSD, from which I know
for sure /tmp is cleaned at reboot and, daily, files older than
seven days. (Note that we see another benefit of tmpfs for /tmp
and for *most* files here: when mc segfaults again, its tempfiles
will not linger around long when in /tmp on tmpfs…)

Ouch. (But nobody said Staroffice/Openoffice/Libreoffice/whatsitsname
was light.) This sounds like another of these cases where the software
would benefit from changes _independent_ of the tmpfs setting. (It could
for example do that only for the first few pages, doing others as the

I don’t disagree but still stand by that these are corner cases.
