At a glance it looks like what we need to fully support cross-arch releases, as it supports different byte-ordering.
It could also be used to get us closer to "fixing" release/ to not
require "root" privileges -- it could be a very useful feature for
developers with non-root access on fast machine. ;)

I wonder if this 23k difference is on 5-CURRENT or 4-STABLE, or both?
If it is on 5-CURRENT only, does the following patch for FreeBSD's
newfs(8) make any difference:

If you don't bite me, I will try it myself. ;)
Also, it would be nice to backport it to FreeBSD. And I suspect
it doesn't work with UFS2, does it? (We don't need it for releases
presently, but anyway.)
