It sounds good to me: - PACKAGES_PATH is a useful feature and it works well in my experience, so I think having to use PACKAGES_PATH for pulling in edk2-libc should not be a large obstacle. - I'm not sure how closely the StdLib internals are tied to day-to-day changes in core edk2; that is, whether we should keep those histories interlinked. That's something for the StdLib maintainers to evaluate. Personally I don't remember many StdLib changes, so there seems to be a genuine separation that supports the new repo idea. Thanks, Laszlo
