In short, now think it is better not to mention libpam-tmpdir.  That is
why I did not mention it now.  So your patch seems good for me.

PS: My rationale to mention $TMPDIR was to avoid excessive bug reports
on presumably existing DVD-burner programs which write huge data on /tmp
but they honor redirection of data via $TMPDIR.  At least this $TMPDIR
offers a simple work around hook functionality for such programs.  

The environment variable $TMPDIR can be set via several methods.  I
thought libpam-tmpdir is just one of them.  Now that I rethink, it may
not be the best solution since it may interfere too much as you
