Jan Lentfer has committed ldns and drill to DragonFly, in (unlikely) chance that you managed to delete BIND from pkgsrc (installed by default on 2.7+) and somehow couldn’t replace it.
I don’t get the idea, thought bind removal was for less code maintenance in base.
I thought so too, but:
A package that just had the tools would cover all possible situations, I think, but there isn’t one in pkgsrc.
