mender.io is a service which provides the server side for device updates. It's worthwhile to investigate integration with that and document its strength and weaknesses. The initial goal for this issue is just the description, not working code.
I just added Mender here [1], so I suppose you can close this, unless you intend to add more. [1] https://wiki.yoctoproject.org/wiki/System_Update#Comparison
I agree, we can consider this done. Thanks Kristian.
