(aren't they the same thing?) `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. -GAWollman -- Garrett A.
