All discussions solved as of now.
I was told that the documentation was ready to be merged, but I asked to wait till this gets the approval and is merged before (or at the same time at least).
@juliogonzalez , could you have a look?

Python files look good. It seems Salt preflight script is already taking care of Raspbian.

LGTM, thanks!
