Hi folks, hopefully this is posting in the right forum.
I have several RPi's (11 = Zero - 4B models) that I can use a menu based set of setup scripts on (run as root for installs etc. using latest Raspian-Lite image) and most of it works. I can configure hardware per device (camera, GPIO hats etc.) and local installs of OpenMPI with minimal user input, but I'm struggling with setting up RSA shared keys. I can do it with lots of CLI per device during setup, but I'm trying to develop it for educational use, so some scripted commands would be very useful.
