It'd be great to hear a comparison of when you'd want to use Deviceplane vs something like mender.io or updatehub.io. I'm a great fan of the A/B dual image update strategy because it's simple, atomic and resilient to errors or loss of power during an update. Does Deviceplane still provide some of those assurances or would I want to use Deviceplane in conjunction with something like Mender?

I deploy updates on IoT devices that are unattended and can only afford minimal downtime. If an interrupted update (due to loss of network connectivity or power) caused a device to be unreachable/unupdateable it would be bad. I'd also be concerned with using DevicePlane as it's presented because I'd have no way of updating the device's kernel version that I first deploy with.
