`ufs' is the generic ``UNIX-style filesystem with inodes, devices, and
symlinks''. `ffs' is a particular instance of `ufs' with an on-disk
layout policy. `mfs' is a specialized kind of `ffs' which is only
backed by swap. `lfs' is another instance of `ufs', with a different
on-disk layout policy and a couple of system calls.
