Using git bundle looks like an interesting idea, but the solution suggested in the post is seems incomplete:

1. it's only working for master 2. it bundles everything making an update on a different machine more difficult

I'm pretty sure that people that use git bundle extensively know how to handle these scenarios though (I don't)

1. I'm still relatively new to git, so haven't looked into branching, etc., yet. Worst case scenario, add other branches to the post-commit file. 2. It really is intended as a "backup", if I was looking to interact with more machines, I'd setup a central repository that everybody could commit to, and individuals could still use this to backup their local repos.
