Well, that has two problems we have observed in practice: 1. Not all mirrors have up-to-date mirror scripts, and that _does_ include mirrors selected for the multi-mirror aliases; 2. Mirrors in the same multi-mirror alias are not updated at the same time, and it is very possible (especially in http scenarios) to get metadata skew problems across mirrors even when they are perfectly fine and internally consistent. That doesn't even need a third issue (multiple DNS queries) to cause problems, way too many users are behind http proxies and caches that break things regardless. Maybe we should start designing sequence tagging/generation tagging for the metadata? If nobody has time to implement it right now, it would be a damn fine GSOC project for 2013... -- "One disk to rule them all, One disk to find them.
