But SysV is not BSD.

Yeah, I found that odd also :)
But, there is also "using the sources", on OpenBSD-current
/usr/src/sys/ufs/{ext2fs,ffs,lfs,mfs,ufs}
and on FreeBSD 4.9
/usr/src/sys/ufs/{ffs,mfs,ufs}
which makes me think FFS is based on UFS. So, yes it's UFS, with some
additions.
And the softdep stuff is under ufs/ffs, which would lead me to believe
that that is the currently used system.
This goes with what is said at
http://en.wikipedia.org/wiki/Berkeley_Fast_File_System
As well, http://sixshooter.v6.thrupoint.net/jeroen/faq.html#UFS-DIFF-FFS
(discusses UFS2 differences also)
If "The Linux Documentation Project" has "[old]" documentation currently
available their website ...
