In NetBSD-land the file system is FFS. The thing we have in NetBSD
called "ufs" is a directory of FFS-related code that's also shared
with LFS and the ext2fs implementation.

There's a version 2 superblock format that has no relationship to
FFSv1 and FFSv2 per se. It is used by both FFSv1 and FFSv2 and also (I
think) by LFS.

It is all very confusing and poorly documented. It doesn't help that
our attempts to standardize the terminology have diverged from other
groups.
