<div><br></div><div>If you don't believe security is possible... that's fine. Because perfect security is impossible. But, that doesn't mean people shouldn't try. CentOS *does* sign SRPM, do they not? Why do they do this? Obviously, somebody believes this aspect is important?</div>
<div><br></div><div>It seems like some people just want to do what they're already doing (for better or for worse) and it doesn't really matter what the request is, or the merit of the request. Which is fine... but just please admit to it.</div>

If, as Nico suggested, <a href="http://git.centos.org" target="_blank">git.centos.org</a> was pwned, then CentOS just certified bogus sources. IOW, a signed tag from Jim, or Johnny, or KB, or any of the other CentOS devs means precisely fuck-all, and not a bit more, because they get the sources through the EXACT SAME distribution channel that the rest of us do. CentOS is not special, they just look that way. Really, if this is the assurance you want, just add your own signed tags to your local repo -- it's just as meaningful.<br>

<div><br></div><div>What do we want? FUCK-ALL! When do we want it? NOW!<br></div></div></blockquote><div><br></div><div>You are right about "just add your own signed tags". Actually, everybody who derives should sign what their derived works. That makes it possible to track back if or when something bad does happen, and we can see where the problem was introduced. So RedHat should sign their tags, and CentOS should sign any tags that they create. It's not "FUCK-ALL"... It's evidence that a particular process was followed that was approved by a particular person. It's a paper trail that is more difficult to forge. It's not different from a signature on a form authorizing a change. Yes they can be forged... but that doesn't mean that "no signature" is better than "signature that can theoretically be forged".</div>

Otherwise it's just garbage in, garbage out, and they're only certifying that the sources you download match the sources someone else downloaded. I guess misery loves company, but that sure doesn't seem helpful.</div>

It sounds like extending your thinking would conclude that signing the SRPM is also useless. And for this... if you really do think this... I think you are quite wrong.</div>
