I was just looking at what resin.io are doing for managing big fleets of embedded devices and it seems like there are some things we can learn from them.

Basically they have a very lightweight base OS image https://github.com/resin-os that is based on yocto (http://www.yoctoproject.org/). Then everything is an app that runs inside of a docker container. When they need to provision updates, what they do is they push a new docker image to the docker repositories and then pull it in from the devices.
The devices are managed via a VPN that allows them to reach devices behind NAT.
In particular they have a supervisor that is written in go and based on docker for running "apps" on their devices:
A captive portal like thing for connecting devices to wifi networks:
