It appears littlechef doesn't respect ForwardAgent.

I have a chef cookbook which attempts to do a git checkout of a repository. Rather than having to generate a deploy key on the server, and adding that to github, you can enable ForwardAgent.

It seems this does not work. I can manually login to the server using ssh -A root@domain and git clone fine.
Setting ForwardAgent yes in my ~/.ssh/config doesn't have the same effect.

Any ideas?
