The hypriot guys are doing great work, and we share a common mission in spreading containers to embedded development. ResinOS is built with production deployments as a first goal, and so has a read-only rootFS, supports atomic host OS updates, is ported (and portable) to a lot of device types (via Yocto) and in general has many more "embedded" characteristics than Debian, on which hypriotOS is based. I do however want to reiterate that we know the Hypriot guys decently well and appreciate the work they're doing to make Docker accessible to embedded hackers.
