Your analysis and approach make sense to me, even though it's regrettable that it is necessary. I guess UFS needs zfs-style feature flags.... What about compatibility with FreeBSD? - What happens if someone takes a FreeBSD UFS2 filesystem and mounts it under NetBDS 9? - What happens if someone tries to mount a NetBSD <=9 UFS2 filesystem on FreeBSD? A 10 UFS2 filesystem w/o ea? with? Or is it already the case that FreeBSD and NetBSD do not interoperate with UFS2? And same questions for the other active BSD variants, which I think is mostly OpenBSD and Dragonfly these days but I have lost track.
