I'm looking to dual boot between two root partitions.
I want to upgrade the other partition and then modify
/boot/cmdline.txt to reboot on the newly upgraded partition.
There can be different kernel versions on the two root partitions.
/boot/config.txt I can configure the path to
where part2 is a folder on the boot partition.
I assume the overlay folder must match the build of
Where do I place the
overlay folder? in
Can the overlay location be customized?
