It's normal for there to be nothing there until you have booted from
grub (after changing this option). Have you done so? If so, the
problem may be that you don't have a writable grubenv for some reason.
If you press "c" when you get to the grub menu and then run "save_env"
it should test this. If it returns without error, your grubenv is
writeable, if it gives an error message then it's not.

Is it an ext4 filesystem on top of another abstraction like LVM or
RAID? Either would prevent grub from writing to grubenv for safety
reasons.
