As I recall, Apple's launchd is a replacement for rc (and init and inetd),
and runs in parallel.  (My Mac does start up very fast indeed, though
launchd is not the only reason)

There is/was a SoC project for bringing it to FreeBSD:

It'd be neat to have in DragonFly, though it would appear to require some
quantity of work.
