For some weeks, I have on-and-off been trying to create my own mirror of cvs.drupal.org in Git, and now it seems I've finally succeeded.

I have set it up with Gitweb and everything, and it seems to have complete fidelity with regards to the original data. It has all the branches/heads and tags that Drupal has, meaning that you can use checkouts from this reppository to keep your Drupal installations up-to-date.

Here's the links:

Repository (git clone this): http://git.lion47.com/drupal.git/
