That is how I setup my netbook with a crappy SSD.  /tmp is a large tmpfs
with /var/tmp symlinked to it.  /var/run, /var/locks, and /var/log are
all fairly small tmpfs mounts.  I was originally going to just /dev/null
most of the logging but then I decided that was too much of a PITA if I
ever needed to debug something.  This way I still have logging it just
doesn't survive a reboot.
