Is there ANY way to get an older update? So that if new version of a package is causing a problem I can downgrade it? By default yum is configured to remove some older versions of kernel, so now I'm having problems downgrading it. E.g. where could I get kernels: xen0 & xenU: 2.6.17-1.2157_FC5 I know it was not the smartest thing to run Fedora (at least with Xen3) on a production server, but it was working fine for some time and i would like to get back to that state: https://www.redhat.com/archives/fedora-xen/2006-September/msg00009.html
