Getting the Source

git clone http://dracut.git.sourceforge.net/git/dracut.git

If you have committer access to Dracut, then you will want to use the git+ssh access url.

git clone git+ssh://dracut.git.sourceforge.net/git/dracut.git
git clone http://dracut.git.sourceforge.net/git/dracut.git

Once you've committed changes locally, you can push them with

git push
