i made a bush_league mistake. I kept trying to use a dvd to print a 16gb image to.

Duh...:-\ And now I have to start all over again and begin with the head of the cluster. Well, the cluster is called a bramble, so we'll call this first one the root ball. It'll have a 32 gb SD card and a WiFi AND rj45 plug

I will use the WiFi for the communication between nodes and the rj45 will be the connection to the rest of the world, so to speak.
