Would it make sense to have some mechanism for substitute servers to be able to provide a sort of "non-existence proof" for a given package? Something that the CI system could publish to indicate that its build attempt for that package failed, and that clients could use to optionally abort without attempting a local build? My reasoning for this is that, especially on some of my smaller ARM systems, a build attempt for some of these larger packages can take several hours, and if it's likely to fail I'd really prefer to know that ahead of time. --76b61996a5e447ab94c0a1cffdbc8e68 Content-Type: text/html Content-Transfer-Encoding: quoted-printable
