The whole thing seems unnecessary to me once efilinux is taken into account. I'm curious what your (Garrett's) opinion is of that. Why do we need all the machinery of grub these days? Is it just that efi doesn't/can't provide the necessary boot menu to allow us to select kernel version and boot parameters?
You've evidently decided that grub-efi is the way to go, but I missed whatever post explains what that gives us over using efi directly.
Thanks [and double thanks for fighting through this hardware nonsense all the time]
