Look at the mfs reference page.
There is an undocumented upper limit on the size of the mfs file system you
can define in your /etc/fstab using the technique in the reference page; the
limit seems (empirically) to be about 64MB. If you want to set up an mfs to
always be created at system startup, then in your /etc/fstab put a line like
this:
/dev/rz0b /tmp mfs rw 1 2
instead of a line like this:
-s262144 /tmp mfs rw 1 2
where /dev/rz0b is a partition that is the right size. On my system, I've
got four swap partitions (partition b on rz0, rz1, rz2, rz3) and I use lazy
(deferred) swap allocation, so what I'm doing is setting an mfs on /tmp to
use about 25% of the swap space (if it needs it). This works fine for me.
