FreeBSD 5.0 now has the NetBSD rc.d system; although some of the
scripts might have different names (due to divergence in the systems
and services), the general operation should be very similar.
FreeBSD has also has the NetBSD /etc/nsswitch.conf.   (These are just
some of the examples of ``cross pollination'' of software back and
forth between NetBSD & FreeBSD, which is a good thing).

OpenBSD has neither of these user/sysadmin-friendly enhancements, which
(as far as I can tell) is due to that project's leader objecting to both
concepts.  (Please correct me if I am wrong.)
