I think that it's currently unlikely because Kirk McKusick is the only one
who really understands it, from what I recall of discussion.  Source
upgrades are possible from FreeBSD 4 but not 5, though, so it may not be
as useful in any case.

For now, I'd plan on needing a backup/dump to upgrade to DragonFly from
FreeBSD 5.
