To be fair, the example I have given is simple and you could use something like gitosis or gitolite (I have used them in the past). The point of the article was supposed to be a starting point if you have something else you want to do. For example, I needed to have a fully distributed git backend system across multiple git storage nodes so I needed to learn how I would go about doing that. This post was supposed to give the reader the tools they need to roll their own solution if they want.
