Does anyone still use mrouted(8) or is everyone using dvmrpd(8) now? If you're still using mrouted(8), why?
If no one speaks up in defense of mrouted(8), I'm going to propose that it be unlinked from the build after tree unlock. Currently the userland-kernel interface for managing multicast routing is hard-coded to only support 32 interfaces, and it's simpler to fix one routing daemon than two.
