I have an open RFC, https://github.com/opscode/chef-rfc/pull/20
This proposal describes an enhancement to chef server that allows uploads of cookbooks that are identified by arbitrary IDs. This feature supports the ChefDK policyfile feature, where we intend to identify cookbooks by a SHA-1 hash of the content. This allows users to safely publish cookbook changes without updating the cookbook’s version number if they choose to do so (some reasons why users might want to do this are enumerated in the proposal)
It’s been open for a week and we seem to have reached consensus among the people who have commented so far. I’m reposting in case anyone has missed it that would like to comment. If nothing comes up, I’ll be moving to have this accepted/merged soon.
