As far as I'm aware, there isn't a good way to know. So the caveat is that if a cache has short-filename packages, then it can't handle multiple distributions, unless the packages somehow have the same checksums across the board. (Which is possible for locally-built .debs, I suppose.) Existing caches have basically "thrown away" some of the relevant package information, which the new approach would save, so some additional work would be needed to get that information in for the existing packages. The proposed two-step fallback is less about "let's make existing caches able to handle multiple distros straightaway" and more about "let's not effectively clear out everyone's caches by no longer looking for packages under their old names" :-) -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
