On my current sid system, I do not have tmpfs(5).  Is this something you
will be offering as a part of some package which is normally on system.

(I have fstab(5) but that is not much useful for learning how to set
fstab to change tmpfs size.  fstab(5) combined with mount(8) gives me
better insight but it is not clear enough for common user.)

What people needs to know here are:
 * You can set tmpfs sise via /etc/fstab as described in fstab(5) and mount(8)
 * tmpfs size can exceed available physical DRAM size as long as there
   are enough swap space on disk (including SSD).

Isn't it better to indicate what is the best practice for fix?
 * making program to honor $TMPDIR while admin set it via libpam-tmpdir
 * use /var/tmp hoping it has enough space.

(Please note I have no opinion on above ... if there are better solution
for the problem, plese describe it.)
