Well, kernel is kind of special. Kernel rpms are not updated but installed next to the old ones (keeping last 3 version installed on the system). This is not a spacewalk feature it's standard yum update behavior. So in fact your old kernel is already on the client and you have to reconfigure grub.conf to boot to older kernel. Unfortunately this reconfiguration can't be done via snapshot feature (snapshot can just install back older packages). % Thanks in advance % % > % Hi All, % > % % > % I want to upgrade the RHEL 4 server .
