Docker install: Module aufs not found - again

It looks like you are reporting something as an error that’s not really an error?

I just set up Discourse on a new SFO 2GB Ubuntu 16.04 LTS droplet. I do see the “error” but it just scrolls on by and everything works fine – Docker seems plenty happy, note aufs is there:

After bootstrapping it loads Discourse just fine, following the official install guide, step by step, no deviations.
