Useful idea. One thing to keep in mind when we're talking about the download of historical binaries is the obligations of the GPL, etc, in that regard. Gentoo doesn't normally have to worry about this as it normally ships sources, not binaries, and for current stage tarballs, which /are/ binary, the sources are, pretty much by definition as Gentoo handles it, made available at the same time (tho there might possibly be argument over whether they're made available at the same place, etc, I've made no attempt to grok or verify the legal minutia in that regard). But once you start shipping historical binaries, as we're talking here, we need to worry about EITHER keeping sources available at the same time/ place for them too, as long as they're shipped, OR keeping them available to be shipped upon request to ANYONE for up to three years. Based on previous discussion, the make available at the same time and place clause is considered easier for distributions such as Gentoo to fulfill than the upon request for three years clause. (That's the GPLv2 requirements as I understand them. I don't understand the GPLv3 and its differences in that regard really at all... except that I believe the same basic idea remains valid. IANAL. The Gentoo Foundation folks are the ones who probably should be tracking this. Etc...) This discussion came up at least once before, some years ago, when Gentoo was still making available historic stage tarballs dating back to 1.4 or earlier, and there was some real question as to whether we were sure that all the required sources were still available. I never validated whether action was actually taken, but the conclusion from that discussion, IIRC, was that the best practical action we could take would be to (1) ensure that we always kept corresponding sources from then on and made them available at the same time/place as the binaries, and (2), quit distributing the "historic interest" stages that there was a legitimate question about as to whether we could provide sources or not. Just something to keep in mind any time the idea of public availability of non-current binaries, for whatever reason, comes up. It's not all purely technical worries, tho fortunately, implementation of the legal requirements does ultimately boil down to technical details, too. I'd opine that's one practical reason why binaries remain a definite secondary from Gentoo's perspective -- sources-only lessens the legal requirements DRAMATICALLY, both as regards the GPL, and in regard to patents. Hopefully that's not a discouragement for something that I really believe is a great idea, but it /does/ need to be considered. -- Duncan - List replies preferred. No HTML msgs.
