I see updated xen packages in http://ftp.scientificlinux.org/linux/scientific/5rolling/x86_64/SL/ The x86_64 versions (I haven't checked the i386 versions) have no gpg signature. I know that 5rolling is still a little unsteady, should I hold off from frequent updates on my 54 test machine ? Thanks, -- Dr. Andrew C.
