We could, but I wonder if not touching upstart or sysvinit will be an easy way to handle migration/compat issues. One other thing Greg brought up today was that we should allow an admin to configure daemons to run as root if they want. They can do that by editing the unit files; I'm not sure if we want to do something more friendly than that?
