I've used RAUC (https://rauc.io/ https://rauc.io/) professionally for a couple of projects and am happy with it. There's a RAUC meta layer which provides bbclasses for generating rauc bundles from an image recipe. It's not that complicated to set up boot partition selection in u-boot. For embedded systems, I strongly prefer the "full immutable system image update" approach over the "update individual packages with a package manager" approach. Plus you get rollbacks "for free": if the system doesn't boot into the new image, it automatically falls back to booting into the previous image.

One has to implement the rollbacks in the bootloader after they have implemented an A/B update pattern. In u-boot this is done with its boot count limit config and altbootcmd.

+1 for "full immutable system image update" People who suggest updating individual packages (or even worse, individual deb packages for instance) have never deployed any large scale IoT/Embedded projects. These devices are very different than servers/desktops and will break in ways you can't imagine. We started out using deb packages at Screenly before moving to Ubuntu Core, and the amount of error/recovery logic we had written to recover from broken deb package state was insane at that point.
