Well mate, you did a wonderfull job 🙂 The only thing that afraid me is maintenance. By not using the fog install script, you have to write your own installer, which could be hard to maintain in the future, i think.
But to be clear, this is by far the best/cleanest work i’ve seen since a while (and i’ve seen a lot of them) :). I guess you did spent a lot of time on this. If i had found your work earlier, i would have, for sure, worked on it !
