#      rc_status -s     display "skipped" and exit with status 3
#      rc_status -u     display "unused" and exit with status 3
#      rc_failed        set local and overall rc status to failed

# or restarting a not-running service as well as the restart
# with force-reload (in case signaling is not supported) are
# considered a success.
