Policyfile support should be added to the chef-solo provisioner, similar to how it is supported by the chef-client provisioner. I believe the reason the original PR didn't address the deficiency in the Solo provisioner was due to some uncertainty around using Policyfiles with it. There is an example here on how this works (also illustrating how to use chef export to bundle everything up). Additionally, since chef-solo is now just chef-client in Local Mode, there is definitely support for Policyfiles.

Ideally, it would be nice to be able to use the same control mechanisms in both my provisioning pipeline and my actual production environment.
