+1 for this. I'd like to see the policy and the implementation submitted for review by serious privacy experts.

At this point, IP addresses are decent geolocators when users are not careful to use a proxy of some kind in everything they do. We do allow them to set that up, but casual installers are exposing their IP to us. If I can tell that a machine contacted Ubuntu's security archives at a certain time, I can make a legal case that I should be able to see the logs from the security archives. Right now, all I'd get would be all the IPs that requested updates at that time. The sheer popularity of Ubuntu provides a decent amount of plausible deniability. However, if there's a GUID still on the hard drive, then it does exactly what it is designed to do, disambiguates the event chain, so now someone can "close the loop" and know exactly what IP a machine had at that moment. Once they can rule out a proxy server, this gives a reasonably certain physical location for the machine at a certain time. This is bordering on tinfoil-hat-wearing level of paranoia, but its something that needs to be considered before doing anything rash. -- ubuntu-devel mailing list ubuntu-devel@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel
