To not interfere with any other git repos that may be the filesystem root, this dotfiles repo has been set up as 'bare' (.cfg) with config set as an alias to git. Therefore use config as a substitute for git in any commands related to manageing this repo.
# Set up repo bare to not conflict with any other .git that may be in $HOME
git init --bare $HOME/.cfg
# Custom alias to our dotfiles instance of git to avoid confusion
alias config='/usr/bin/git --git-dir=$HOME/.cfg/ --work-tree=$HOME'
# Don't show untracked files, as this would be our entire system
config config --local status.showUntrackedFiles no
# Add the path to .zshrc
echo "alias config='/usr/bin/git --git-dir=$HOME/.cfg/ --work-tree=$HOME'" >> $HOME/.zshrc
