GNU Arch folks do something similar in their "package-framework" stuff. I however do not think that belongs to the core GIT nor even to Cogito for that matter. To me, it feels like this is a pure build infrastructure issue. I think you could arrange something like that with today's core GIT tools, like this: - Tweak Cogito Makefile so that pure Cogito and core GIT are housed in separate subdirectories; - Add "required-git-pb" file to Cogito source as a tracked source file, and record the required version of git-pb there; - Arrange Cogito Makefile to make sure the subtree that has the core GIT side meets "required-git-pb" constraints. The constraints could be "at least contains this one", "exactly this one". The policy would be differnt from a depending project to another. What happens if the requirements are not met is also up to the policy of that depending project.
