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.
