Uploading only to unstable may cause undue delays. Building against testing instead of against unstable also means you don't have any of the controls testing is supposed to provide to protect against uninstallable packages: as soon as you build a new library package, everything that depends on it is uninstallable. This really makes unstable snapshotting, or building stable once it's released as Anthony has also suggested in this thread, look like much better options than trying to build out of testing. > > For these reasons, I think the snapshotting approach is a better option, > > because it puts the package selection choices directly in the hands of > > the porters rather than trying to munge the existing testing scripts > > into something that will make reasonable package selections for you. > So, why don't you do snapshoting for testing ?

I think we should discuss various solutions to address the needs of porters involved in non-release archs. I think trying to run a full testing infrastructure, or build against testing instead of unstable, is unlikely to be a good solution for those porters in practice because of some of the issues that I've pointed out. -- Steve Langasek postmodern programmer
