So, the folks who are working on bootstrappability have made their decision about the semantics of these profiles, and those that do the work get to decide, and all that. But I don't agree that there's anything difficult to reason about here. The sole requirement that a stage1 package *must* fulfill is that it's usable for bootstrapping any stage2 packages that require this package (or, if no such stage2 packages exist, then "final" packages). The requirement that this be done in such a way that the list of files within the stage1 package is no different than the list of files within a final package is an additional, artificial constraint. I don't believe it fundamentally makes the bootstrapping problem any easier than if this were done ad-hoc. -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.
