> The solution however is very simple, trivial even: just version your entire Emacs config in Git. And all installed packages. > You make it sound like it's not possible to have a deterministic system. It's not just possible: it's very easy If you never update a package or install a new one. The more packages you have installed and use and the more (major and minor) modes you use (simultaneously), the higher the possibility.
