Is this possible and/or documented? I've seen documentation that suggested installing the fedora-release and yum RPMs from the version you're considering upgrading to, but didn't know if this was possible with FC4test1. Yum from FC4 doesn't appear to install/execute properly under a previous version of FC. I guess I've grown to like ubuntu's apt dist-upgrade and was hoping I could do the same under FC. I'm trying to avoid the download-the-iso--then-burn-and-upgrade hassles. Thanks for your help.
