(sorry for drive by comment)

Instead of a straight copy/paste of the code, perhaps it would be good to migrate the code including history (see moby/sys#121 for an example)

Perhaps also separating the integration commits from the follow ups (formatting build tags, upgrading yaml dependency)

@thaJeztah sorry for my late response on this, I was on PTO.
I will update my patch as you suggested.

@fmuyassarov no worries!

Also feel free to "ping" me if you need help with those instructions; I know it can be a bit of a pain to do (and make sure you use temporary repositories on your local machine), but I think it's good to a) preserve history (which can be relevant), and b) preserve the original commits to accredit the authors of those commits.
