Tag: init-d-script-stops-in-s-runlevel Severity: warning Check: init-d Explanation: This /etc/init.d script specifies the S runlevel in Default-Stop in its LSB keyword section. The S runlevel is not a real runlevel and is only used during boot. There is no way to switch to it and hence no use for stop scripts for it, so S should be removed from Default-Stop.
