Am I correct in assuming this means I can (eventually) use PFS without any dependency on Docker? In particular, I'm interested in knowing whether I can expect to be able to run PFS contained within an arbitrary unprivileged container and use my preferred orchestration around it. Or, is it the goal of PFS to take over the orchestration plane, or require CoreOS's? Or, something else?

I love that idea.
