well done, I like that the guide covers the whole story, from the bare metal to actual baking.
shall we put this in the wiki ?
there are several tutorials out there with interesting stuff, taking different approaches on different systems. It would be nice to have all this in one place, I mean collecting in one site all the links to the original material maybe with a brief description. Basically it would be the starting point for anyone looking for all kind of tezos tech info at any level.
