Overview

Chef::Cookbook::FileSystemFileVendor

This FileVendor loads files from Chef::Config.cookbook_path. The thing that’s sort of janky about this FileVendor implementation is that it basically takes only the cookbook’s name from the manifest and throws the rest away then re-builds the list of files on the disk. This is due to the manifest not having the on-disk file locations, since in the chef-client case, that information is non-sensical.
