After reading https://askubuntu.com/questions/1416758/remote-full-system-b... I’ve been debating whether to try this out on some of my live headless pi’s that I manage remotely, but have been worried to try it without a test system first.
Seems like booting into PiCore could be perfect for this scenario. You could even use some of the A/B try-boot functionality that rpi have introduced into the bootloader over the past year.
Been mulling this over for the past couple weeks and then this HN post about PiCore pops-up literally day I was going over that askubuntu post again! I’m taking it as a sign…..
