I started out with yadm but ended up symlinking its .git directory to ~/.git to be able to browse/stage/commit in Fork (https://fork.dev).

To make this manageable, I added this .gitignore:

  \*
  !.\*
  !.hammerspoon/\*/\*
  !.config/\*/\*
  !.ssh/config
  .DS_Store
  .bash_history
  .tig_history
  .lesshst
  .python_history
  .wget-hsts
  .zsh_history
  .CFUserTextEncoding
  .Xauthority
  /.config/mcd/.cache/
  /.config/mcd/.local/
  /.config/legendary/

This makes use of the fact that .gitignore patterns are evaluated in order. It basically makes git only care about dotfiles in the home directory, files under .config, .ssh and .hammerspoon. Specific files/dirs that match that filter can still be ignored (e.g. .bash_history).

This is very straightforward and works quite well, so I don't see the need for yadm anymore. The one issue I have with it, is that in the terminal I'm always in a git context (shown in the shell prompt) in any directory under $HOME.
