update -u Did Not Update Kernel Packages
 

I several Red Hat Enterprise Linux 4 systems. One of them is remote to the point, I'd have to drive to its console to perform a console-based up2date. The other day, I logged in remotely su'd to root, and issued an up2date -u. Some, but not all packages updated. The kernel packages did not update.

Is there a way to perform a full update from the command line, and what else besides -u needs to be specified?

kernel* is not updated by default. It's in up2date's "skip"-list.

you can install an updated kernel with up2date -if kernel or up2date -uf kernel.

if you want it to not be "auto"-skipped when you issue 'up2date -u' you can modify the up2date config and remove the 'kernel*' filter.
