DerekK19 / launch-slave
Created April 3, 2013 05:40
Daemon processes to run Jenkins. This is the only configuration I have found that works: A Daemon config file (plist) will run as root and will launch a shell script. That shell script runs a second shell script as the _jenkins user. This configuration ensures that the launch-slave script is running as the _jenkins user and has got a correct run…
