It exists in FreeBSD because at the time rc.d was introduced into FreeBSD we tried not to diverge from NetBSD too much. The idea was that a script from a NetBSD machine should be able to run on a FreeBSD machine and vice versa. However, that has been (mostly) abandoned now and over the past few years most of the NetBSD compatibility shims have been removed. I don't know if anyone uses this feature on FreeBSD (embedded systems maybe?). Cheers, Mike.
