Thanks Basil,

I'd already tried and it hadn't worked. That's what prompted my
question. Actually, what _really_ prompted it was the kernel update
where the boot menu was left untouched. [Note: 12.3 x86_64 KDE4.] It
booted into the same kernel afterward and there was no new entry in the
boot menu. After invoking 'grub2-mkconfig,' there was still only one
entry in the boot menu, but it booted the updated kernel.

regards,

Carl
