This repository is tracking my home directory using a bare repository.

git-lfs is used to track "larger" files, such as fonts.

Assuming that git and git-lfs is already installed, the following should do the trick:

$ alias dotfiles="/usr/bin/git --git-dir=$HOME/.dotfiles --work-tree=$HOME" 
$ git clone --bare https://www.github.com/wizhi/dotfiles $HOME/.dotfiles
$ dotfiles checkout
$ dotfiles submodule update --init --recursive
$ dotfiles lfs install
$ dotfiles lfs pull

The dotfiles checkout will copy all dotfiles into $HOME, and will fail if any of these already exists. If this happens, the only fix is to backup the existing files and dotfiles checkout again.

It seems like autocomplete is broken for the dotfiles alias, which really sucks.
