from /usr/share/doc/handbook/handbook.ascii
options MFS
Memory-mapped file system. This is basically a RAM disk for fast
storage of temporary files, useful if you have a lot of swap space
that you want to take advantage of. A perfect place to mount an
MFS partition is on the /tmp directory, since many programs store
temporary data here. To mount an MFS RAM disk on /tmp, add the
following line to /etc/fstab and then reboot or type mount /tmp:
/dev/wd1s2b /tmp mfs rw 0 0
Note: Replace the /dev/wd1s2b with the name of your swap
partition, which will be listed in your /etc/fstab as
follows:
/dev/wd1s2b none swap sw 0 0
Note: Also, the MFS filesystem can not be dynamically
loaded, so you must compile it into your kernel if you
want to experiment with it.
