This is the fun way. I have a ton of configuration files in git and I symlink to them from various places with an install script. And zshrc has enough brains to determine the OS it’s running under and the hostname. Between those two, I can have it do all the Right Things no matter what system it’s on. So far, it deploys to my personal Mac, my work Mac, my personal Linux box, my SDF account, and my Android phone with tmux.
Basically I clone the repo into .local/share/beejsys and then run the install script and everything just works. And I don’t typically have to rerun the install script after a pull.
