RE: question reguarding upgrading kernel

ELIO behaves like a mix of GRUB and LILO.
You can add a new boot option by editing elilo.conf.
You can even edit elilo.conf (as with GRUB).
elilo.conf is somewhere in /boot. I've seen it in a number
of places but /boot/efi is typical (location is vendor/version
specific).

You can just duplicate an existing entry but put your
new kernel information in place. Make sure you put the new kernel
parts where they belong and create the appropriate symbolic links.
Also, use a different label.  (You do not _need_ to have the 
kernel compressed btw).

>From the efi shell, you can examine the contents of elilo.conf.
Use "edit" to edit and I think "type filename" also works.

Once you are at the ELILO prompt, you can hit <enter> to boot the
default kernel or enter the label of the kernel you wish to boot.

Like GRUB, with ELILO you do not need to re-run anything after
you have written to /boot.  

As someone who has forgotten this once or twice, do not forget
to include FAT as a valid FS.....as /boot is on a FAT partition.
