I follow a similar but handcrafted approach. I have a dotfiles repo with a setup script that automates the creation or deletion of all the symbolic links: https://github.com/susam/dotfiles/blob/master/setup

So what I do on any new system is just:

  git clone https://github.com/susam/dotfiles.git
  cd dotfiles
  ./setup

And if I want to undo all the setup for some reason:

  ./setup rm
