While I like the current GRUB2 behavior in F17 vastly better than
F16, I kinda wonder if it makes sense to change the default behavior to save last chosen
option and by default use that the next time around, rather than always defaulting to the
most recent Fedora kernel. This allows dual-boot users to choose Windows (or Mac OS) once,
and consistently get that as their default boot option, rather than having to manually
edit GRUB's configuration files to get such behavior.
To change your default option, just edit /etc/default/grub and set
GRUB_DEFAULT to match the label or entry number or "saved".
grub2-mkconfig will respect that decision (or it did, the last time I
used it)
