For example, I tried mirroring a CentOS mirror and left [centosplus] in my local.repo file, but didn't mirror the centosplus tree. Of course it didn't find repomd.xml for centosplus, so it just quit. So check the [update] repo pathing in your /etc/yum.repos.d/ file that you're actually using first. I should mention that when I first saw the FC4 Xen howto that used yum to create a core filesystem, it worked for me when creating a UML rootfs. I'd consider that some of the newer Xen scripts in FC6 might also prove useful for creating UML root filesystems, too. http://uml.jfdi.org/uml/Wiki.jsp?page=BuildingRootFileSystems http://uml.jfdi.org/uml/Wiki.jsp?page=UMLRootFilesystems Jed
