Minor Description
CDH init scripts exit with both 0 and 1 when calling stop on a stopped service. It's common to exit successful when stopping an already stopped service.
LSB agrees with this: "In addition to straightforward success, the following situations are also to be considered successful: ... running stop on a service already stopped or not running"
