Running MRTG on unRAID

MRTG or "Multi Router Traffic Grapher" is a tool to graplicy display stats for your router, server or pretty much anything you want to monitor via SNMP.
It's published under the GNU General Public License which means you can do most things you want with this software as long as you do not claim you created the software and don't sell it.
So I tough it would be fun to run this on my unRAID server, so here is how I did.
