Folks, While tooling up to run batch services on SL302 I discovered that I could not get YUM to update the kernel-module-openafs-* RPM to match the kernel update applied by YUM duirng kickstart. AFS therefore doesn't start becuase of the kernel module mismatch. It would appear this is due to the kernel-module-openafs RPMs having the kernel version number as part of the package name and YUM is unable to recognise that the version for 2.4.21-15.0.3EL.spm is an `update' for 2.4.21-15.0.2EL.smp. This is with yum-2.0.7-1.SL.noarch.rpm. Connie has provided a solution. There is an new YUM in the SL/contrib hierarchy (yum-2.0.7-2.SL.noarch.rpm) which fixes this particular problem - it works when used in our PXE/kickstart system. Thanks Connie...
