Agree w/Paul - crontab is for periodically running things, not to start a
daemon on system startup.
To add a little bit more to what he mentioned, you may want to have a script
that accepts a parameter indicating if it's "start", "stop" or "restart" (e.g.
stop then start) for the daemon. Then
Thank you! I am excited about thos opportunity. I need some of these.
