Duplicating the controller disk image

[Alberto]

After I installed and configured all my software in the controller, I would like to make an image and use it to duplicate
the controller for serial production. But there is a problem of the serial number and NIC address.
Do you have any utility to duplicate controller for serial production?

You can change the mac address in /boot/config.txt (or run revpi-factory reset). The serial number is only used to generate the hostname. So either change the hostname to sth generic, modify each controller after flashing or leave it as is.
