    Allow rc.d script to provide "status" method, even if it does not
    define procname or have a PID file. This might be useful for cases,
    such as mounting local FS, when there is no running daemon
    still some other persistent state in the system which status
    can be checked.
    
    It is still possible to have a status method before this by having
    extra_commands="status", but it's not obvious and might give
    an script writer some extra legwork to figure out how and why
    the straight method is not working.
