One thing I'd like to make clear is that the current proposal was for
changes to sys/ufs/ffs, not for the creation of sys/ufs/liffs. As such, we
can't g/c too much old stuff for the new fs as the same source feeds both
the small and large inode fs's. Admittedly we could use tests for gunk we
didn't support, but couldn't we do the same thing with versioning the fs?
I mean we could do all that on a small inode system.

Sure the magic number is different, but that's because the on-disk inodes
take up twice the space (you get half as many to a disk block). But our
intent was that it was still ffs.

Take care,

Bill
