An init script for managing delayed_job

If you run delayed_job as a daemon on a server, you’d probably like a way to start it when the system boots. Furthermore, you’re probably using RVM at this stage, which requires its own finicky management details within a script. This little init script will handle all those details for you and make starting and stopping the delayed_job daemon a straightforward process.

You’ll want to modify paths appropriate for your system. Also, although this init script is tuned for Gentoo, it can easily be adapted for Red Hat and other Linux variants.
