As I already have written here, there are many very simple solutions, like: - not using downloaded repomd.xml if we already have a newer version (Seth replied to me that using a temporary 2 KiB file instead of instantly overwriting the previous one is a waste of resources, ha ha), now it happens to download old repomd.xml, when most mirrors host newer primary.*. - using versioned file names, like primary-<repotag>-<version>.xml.gz and keeping them a week or two back. This way, if we need current primary-fc7-124.xml.gz, we'd never download anything from servers not synced yet (they'd just give us a 404 instead of useless 2,5 MiB .xml.gz or 4 MiB .sqlite.bz2) and if we need older primary-fc7-120.xml.gz, probably first mirror tried would provide that to us. Both changes are trivial and don't break any compatibility (first one is in yum itself, and the second is only a change in <data><location />, which affects only the publishing system, not yum nor any other depsolving updater). > On top of that the wasted time when this blocks access to the > repositories for a normal pirut/yum install. Try to tell that to them, the proud Americans with their gigabit links and always in-sync mirrors. Maybe they'll send you a respin CD or tell you to leave the computer on for a nightly update. Yes, I'm aware that this comment isn't very helpful, but these are my feelings based on reading this list and I want to express them. Thanks for patience, Lam
