I have one SD card image that I have updated/upgraded and added packages to my liking. I am using this image as a base for any additional SD cards I will be using in other Pis.
This works just fine. I create a disk image with dd. Questions: 1) In creating an exact copy of the SD card, I am also picking up the MAC and serial number of the original Pi, how do I maintain the MAC and serial for each additional Pi I plug the cloned SD card into? 2) Is there a way to determine the burnt in MAC of each NIC?
