ah, thanks, yeah, I figgered that out a couple hours ago with the help 
of the #centos crew.  



RHEL/RHN w/ up2date won't do kernel updates unless you expressly allow 
it with --force or something...   

I know you can put a "exclude kernel*"   into yum.conf or .repo  but 
then, can you then override that without re-editing the conf ?
