Howdy. I have boxes with lots of real RAM, and don't enable swap in the kernels I use there. Are we really sure you MUST have swap enabled for Docker to work?

Ref: http://stackoverflow.com/questions/28838809/docker-warning-on-cgroup-swap-limit-memory-use-hierarchy

That seems to indicate that Docker can run fine without swap instrumentation enabled in the Kernel.

Cheers, and happy New Year! :)
