 I didn't say that it's impossible, I just stated what would be
required. There are no plans to do any such thing in DragonFly BSD, as
there is pretty much no point. Doing it in any other way than with the
separate /boot partition overcomplicates everything by an order of
magnitude (since, for example, the setup cannot occur in userland
anymore) for no real benefit.
