We now have a very nice port by Naoya Sugioka of TMPFS from NetBSD
in our main development branch. It is brand new and still considered
experimental but should be reasonably stable.
TMPFS is a better alternative to MFS and MD for temporary filesystems.
It doesn't have the data duplication issue that MFS has and its data
is swap-backed using a very nice algorithm that only pages data to swap
when the system is under real memory pressure (and not due to buffer
cache flushes, fsyncs, or anything else).
