Just a heads-up: https://docs.docker.com/engine/reference/builder/#maintainer-deprecated

@rzr What's the purpose of this since we already have a full production-ready Docker image?

[rzr]

it can be used for testing local changes on a fresh env

[mrstegeman]

It would probably be useful to allow sharing in the ~/.mozilla-iot volume.

[rzr]

Actually I prefer to not mix previously used contents, I prefer to start on blank container to make sure everything is reproducible on the current codebase, but I can submit a config sharing change in later commit.
