But why are you running grub-install? You do not have to re-install GRUB after every kernel update like you do for LILO. The configuration file only needs to be updated, which is done automatically by rpm when you install a kernel. You should only run grub-install again if somehow your MBR gets corrupted and your machine won't boot (you have to boot with the recovery CD). Back to your question, you can always try running the grub shell and typing in the commands and see what happens. Of course, you'll have to figure out what each of the variables would be. You can also check the log file; look for it under /tmp/ Jonathan
