Very good question. We find that we have to add functionality for the embedded world in quite a few cases, and part of the resinOS roadmap is to package that up for the OS. But the base Docker, other than its recently growing size, is a very strong foundation, and one that keeps improving. We're particularly excited about the new security features and in general our approach is that we can move a lot faster by filling the gap between Docker and embedded devices, rather than starting from scratch and building Yet Another Container Engine.
