[Tfug] Small-ish (capacity + size) disk alternatives

[TR]

Something like this will map ram to a filesystem.  Put it in an init
scripts.

    if [ -e /dev/shm/.mounted ]; then
      echo "/dev/shm is already mounted, nothing to do"
    else
      rm -f /dev/shm
      mkdir /dev/shm
      mount -t tmpfs shmfs -o size=16384M /dev/shm
      touch /dev/shm/.mounted
</snip>
