I find it interesting that you say that, because my first thought was that this would be a step down from git pulling my dotfiles. All you need is to have a simple script that goes ln -s .zshrc ../.zshrc in your .dotfiles repo and getting a new shell up and running is as simple as running git pull && .dotfiles/setup.sh.

I like the idea of this in theory if you have machines that are frequently touched/overwritten, though, if you just want to have a baseline of sanity on them automatically when you log in.
