I use dual installs, since it makes my life easier, and lets me modify the next release
before I actually start using it. Also makes it easy to roll back.

The starting point is a SD card with a snapshot image written, and I added an additional 21.02.01 to the same SD card, then rebooted into 21.02.01.
This is all done from the already running snapshot version
