That'd work pretty well, indeed. It would also have the advantage of making it theoretically possible to reverse the addition of the signatures again, should one want to re-verify against the original .changes file for some reason. That's of course assuming that the combination of "ar a" and "ar d" in whatever way dpkg does that is idempotent, but I don't see why it couldn't be. And as you say, this can be implemented in dak. That would have the advantage of not requiring keys on the buildds. So now that it's been reduced to a technical problem, who's going to do the implementation? I'm prepared to look at a dpkg patch, but Python just does not work for me. > There are other implementation methods possible, but that's probably the > most obvious one. Yes, agreed. -- The biometric identification system at the gates of the CIA headquarters works because there's a guard with a large gun making sure no one is trying to fool the system. http://www.schneier.com/blog/archives/2009/01/biometrics.html
