I have found the following rc.d script for running node.js/forever apps under FreeBSD. I'm not an expert, but the script looks fairly well-structured. The problem is, it doesn't fork the process into the background. And since this runs in a jail, that means that 'service jail start' never completes. Here's the script (which I found at https://gist.github.com/jellea/6510897), along with a dialog showing how I enable it, and what happens when I attempt to start it (along with a ^T and a ^C at the end). The only work-around I have at this time is to leave the service disabled in /etc/rc.conf, and start it manually from the jail's /etc/rc.local with '/usr/local/etc/rc.d/iws onestart &' so that the start-up script is forced into the background. How can I modify this script so that it will start cleanly in the background? Thank you! Please cc: me on any replies sent to the list.
