After making sure that there are no uncommitted changes, etc.:

$ mv repo/.git repo.git
$ git --git-dir=repo.git config core.bare true
$ rm -rf repo

The problem with the above process is that it doesn't take into account future internal changes of Git. A safer method is to let Git handle all the internal settings for you by doing something like this.

* ssh to remote server
* git clone --bare -l <path_to_repos> <new_dir>
* renamed old repository directory
* renamed new repository dir to what old repository used to be.
