Hello: I'm working on automatically supporting dependencies with b4, and I'm curious if "base-commit" should be used to indicate where to start applying dependencies, or if that's purely for the patch series itself. E.g.: base-commit: [commit-ish] prerequisite-patch-id: abcd...1234 prerequisite-patch-id: cdef...3456 In this situation, does base-commit mean: 1. where to apply abcd...1234 2. the sha we should find when we apply both prerequisite patches In theory, #2 makes no sense, because we don't know where to apply prerequisite-patch-id's and therefore can't reasonably arrive at whatever is specified as "base-commit". I expect the answer is "it's whatever you think it should be," because prerequisite-patch-id's aren't really widely used, but I'll be happy to learn that there's an established practice. -K
