Thanks. Appreciate the link. This sort of does it, was hoping that I could leave both running and just switch, each one sort of running in a container. Did lots of unix 40 years ago, don't remember too much, know windows and would say i want 2 vms, one with each os running that i could switch between. booting on the pi is pretty quick, but it then has to load everything.
Actually, I am wondering if I can just read off my
nmea bus to display on opencpn? Mostly looking at
battery stuff from
victron devices.
