We've just released our puppet repository into a public git
repository. For more information, see the blog post about this:
As noted in the blog post, we are releasing this to treat operations
like a software development project. Users with Labs access can push
changes to the repository. We aren't currently ready to start giving
out Labs access en masse, but will hopefully have a process ready by
the New Orleans hack-a-thon.
More info to come about Labs later.
