so this may be an odd question, but my google fu seems to be failing me. I've created a local mirror of centos 5 & 6 with various instructions across the net, it seems to be functional, syncs on a regular basis,and is generally usable (I've built machines with kickstart/netboot from it and they seem generally workable). my difficulty comes up when I try to use the local mirror for system updates. if I use the originally installed repo configs and run yum check-update, I get a list of 10-15 RPMs for updates, if I change the repo files, do a yum clean all, comment out mirrorlist and uncommenting/chang baseurl= http://localmirror/path/to/repo and run a check, I get nothing. if I look in localmirror:/path/to/repo and do a find for the version numbers I got as available updates from the remote repositories, I find appropriate files in seemingly reasonably named directory paths. my current best guess is that my repodata/repomd.xml file needs some sort of update/rebuild via the createrepo script, but I can't seem to find the 'right' way to this. does anyone have any pointers? thanks. -- Even the Magic 8 ball has an opinion on email clients: Outlook not so good.
