speaking of said 2.6.9-42.0.8.EL kernels... updated my vmware guest centos's tonite (32bit guests on a 64bit RHEL4 host), and blam, they lost access to the vmware network adatper, eth0 didn't show up at all on them. rolled back them to 42.0.3 and eth0 reappeared.
You have to rerun vmware-config-tools.pl on a kernel change (if the vmware-tools is installed) to produce new kernel modules.
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 ?
