We should install a tmp-cleaner on Linerva. Today we nearly hit 50G.

finds seven files. None of the owners are logged in. I'm going to
remove them with /bin/saferm (like debathena-tmp-cleaner uses.)
Then we can deal non-urgently.

Done.

We should still set up a real tmp-cleaner.
One obvious choice is debathena-tmp-cleaner, which as written removes
files in /tmp older than 2 days and in /var/tmp older than 3.
But it refuses to remove files owned by users who are logged in, no
matter how long ago the file was last touched. Since the history of
-tmp-cleaner is that ghudson wrote it in July, I suspect that this was
motivated by the cluster situation where a logged-in user "owns" the
machine and may as well do as they please in /tmp/. For Linerva we
may want to vary this behavior.
It might also be nice to use upstream software. Any recommendations?
