Some observations:
* kexec-tools, xinetd, rp-pppoe, hylafax
  Those are legacy initscripts which are still tracked by SVN but not
installed in PKGBUILD (and not present in packages).
* pound/pound.runit
  Runit is an alternative init system... I'm not sure how it intergrates with
Arch and whether the corresponding startup script actually needs rc.conf.
