That's interesting. I've been looking for an angle on embedded Linux software updates for my deployment tool (currently limited to updating desktop and server apps only).

When you say push, do you literally mean push or do you mean the devices would still pull updates on their own schedule where you get to control rollout percentages, channels, etc centrally? Mostly devices have to be assumed to be behind NAT, right?

What I'm thinking here is maybe it'd be useful to have a mode in Conveyor [1] that builds a standalone ARM Linux that can boot and pull updates for everything including the app, but which coordinates with the userspace app to decide when it's time to restart and for which the build to update to is controlled by server-supplied metadata so you can divide the fleet by tag, etc.
