Under debian Lenny, the /etc/init.d/jenkins status script always exit with return code 0, even it the service is not running. According to LSB standard, the return code should be the following:

• 0 program is running or service is OK;
• 1 program is dead and /var/run pid file exists;
• 3 program is not running.

Found on https://fedoraproject.org/wiki/FCNewInit/Initscripts#Init_Script_Actions as official LSB website is currently down.

This fixed status code is quite annoying if we rely on the init script for monitoring purpose.
