That banner is automatically generated by grub2-mkconfig, and is
incorrect. (I meant to file a bug for that ages ago and completely
forgot. Looks like we're stuck with that till F17 now. *sighs*)

Fedora does not use update-grub like Debian and Ubuntu to generate
grub.cfg. It instead uses a tool called grubby, which copies the
configuration for the most recent kernel, only modifying the kernel
image and initramfs to match the new kernel. This permits Fedora
users to safely edit grub.cfg.
/etc/default/grub is only used by anaconda during initial setup, and
when the user manually runs grub2-mkconfig.
