# Required-Stop: $network
# Should-Start: $portmap autofs
# Should-Stop: $null
# Default-Start: 3 5
# Default-Stop: 0 1 2 6
# Description: Starts the xinet daemon. Be aware that xinetd doesn't start if no service is configured to run under it. To enable xinetd services go to YaST Network Services (xinetd) section.

#      rc_status        check and set local and overall rc status
#      rc_status -v     ditto but be verbose in local rc status
#      rc_status -v -r  ditto and clear the local rc status
#      rc_failed        set local and overall rc status to failed

# 2 - invalid or excess args

# 6 - program not configured

# Note that starting an already running service, stopping
# or restarting a not-running service as well as the restart
# with force-reload (in case signalling is not supported) are
