@collinmcneese there's a spec failure here

I suspect the reason we didn't do this originally was RHEL 5. It looks like it works fine on RHEL 6+. We'll see when we bring it into chef/chef.

Yeah that was strange, there is no reason that should have failed, perhaps something transient with artifactory at the time
