Hello,
I was running DOCKER Ce just fine and after updating the host kernel everything stopped working. I keep getting an error about overlay not being supported.

Running: Linux docker-1 4.4.0-72-generic #93-Ubuntu SMP Fri Mar 31 14:07:41 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

On an LXC container:

warning: /proc/config.gz does not exist, searching other paths for kernel config …
