I just replied to myself with an edit to the higher level comment. Sure, I use IPv6 with SLAAC. I'd never needed a separate daemon to handle it, though. I hadn't imagined that OpenBSD would pull that out into its own program, but I'm not at all surprised now that I've heard about it.
ah - gotcha! Yep. OpenBSD is big on the least-privilege principle, Which IMO is why it's pulled out into a separate daemon that only has the permissions and visibility to do what it needs.
Yeah, that seems like a very OpenBSD thing to do, and I mean that positively. It just initially struck me, like, "yay, I no longer have to install a ping daemon!" "A what daemon?"
