This init.d script for starting a Pylons application should be usable on Fedora, Red Hat and CentOS Linux distributions. I have personally tested it on Fedora. I tried to maintain the look and feel of other Red Hat style start scripts as much as possible. To customize it for your Pylons application, simply change the parameters marked in "<>" brackets. Also, you will want to verify that the paths to Python and Paster are correct and modify the pid, lock and log paths if desired. Note that this script starts with "reload" enabled. You can simply remove that line if you don't need it.
To use chkconfig to start the application in default run level modes, after copying this script to /etc/rc.d/init.d/<app_name>, do the following:
chkconfig --add <app_name>
chkconfig <app_name> on
chkconfig --list <app_name>
