Expected result:
no grubby crashes and an updated grub.conf so that I can boot into updated kernel.

Additional info:
No brtfs here and / and /boot are LVM with ext4. This has been an issue for me for all of the kernel updates for Fedora 13; a kernel update has never worked.

I have to edit grub.conf with the updated kernel info.
