Would something like the following suffice? 1) swapon /dev/ramzswap 2) mount -t tmpfs -o size=1G,nr_inodes=10k,mode=0700 tmpfs /space http://en.wikipedia.org/wiki/TMPFS The linux kernel should swap out tmpfs pages that have not been frequently used, so this should be fairly close to what you want. tmpfs is probably a better fit for this than vfat anyway. -- John C.
