> have not yet found a hardware independent Linux distro that can be reliably updated in an IOT context

I'm part of the team that builds an immutable distro based on OSTree (https://www.torizon.io) that does exactly that.

Docker/Podman support is first-class as the distro is just a binary, Yocto-based one that we maintain so users don't have to. You can try our cloud for free with the "maker" tier. To update a device you just drop a compose file with the web ui and massively update a fleet. You can even use hardware acceleration from the containers using our reference OCI images.

The layer is open (https://github.com/torizon/meta-toradex-torizon) and will get Raspberry Pi support soon but you can integrate already easily with meta-raspberrypi (we can also do this for you very quickly ;-)).

Happy to answer any questions.
