Running "git init" in an existing repository
Running git init in an existing repository is safe. It will not overwrite things that are already there. The primary reason for rerunning git init is to pick up newly added templates (or to move the repository to another place if --separate-git-dir is given).
Working with the template directory
By default, git init will populate your new .git directory with the contents of /usr/share/git-core/templates/, without overwriting existing content of the same name:
