I wonder if this could be used to get Docker running on a Mac without painful file system performance (a la Docker for Mac, running Linux in a VM). Could something like this project work for that? Are there Darwin equivalents for container stuff like namespaces?

Maybe it could work. The Mac is odd though in not having bind mounts so it is not going to be easy to fix the filesystem performance using this. Would use less memory though potentially. Maybe you could fake binds in the emulation layer.

(I work at Docker and used to work on Docker for Mac).

? Docker on Mac uses HyperKit. Mac already has container primitives and a hypervisor.
