I was looking through the archive and noticed this thread... https://lists.dulug.duke.edu/pipermail/yum/2005-January/005854.html in which someone asks about whether yum will ever support upgrading between distro releases. The response was that there are a number of things you'd never want to do on a running system including messing with disks and partitions. But then there was this thread... https://lists.dulug.duke.edu/pipermail/yum/2005-January/005842.html in which someone (in the second message) describes installing the redhat-release and yum rpm's from FC3 with --nodeps and then executing a "yum upgrade" to upgrade to the new distro. Viola! My questions are these: 1) For distro-upgrades in which you don't need to mucky with partitions/disks/lvm, etc., is there anything wrong with the method used in the second thread? In my experience it works fine, other than occasionally needing to uninstall a few packages to meet the required dependancies. 2) If the method will reliably produce an upgraded system, I'd like to suggest that yum be modified to do this automatically when "upgrade" is specified. (that is, install the redhat-release and yum rpm's from the new next distro, and then complete the rest of the yum upgrade routine) 3) Why is "upgrade" described as deprecated in the yum man page anyway? -Val ------------------------------------------------------------------ Val Schmidt Lamont-Doherty Earth Observatory of Columbia University 61 Route 9W Palisades, NY 10964 m: 614 286 3726 vschmidt[at]ldeo.columbia.edu
