Running 1 node.js app in a screen window works fine for developping and testing but for my Ghost blog i need a more stable solution. One that starts automatically when the Synology reboots for example.
This article Making Ghost run forever explains your options, however, your Synology does not have the easiest option (supervisor) installed. Also not the /lib/lsb/init-functions that would make your own rc.d script easy to write.
I found that supervisor is not available as a ipkg package so i tried to build it myself.
