Well it cannot, elilo.efi has to be placed to /boot/efi, install path is however /usr/lib/elilo/elilo.efi. > > So how can anything that is .efi _not_ be in /boot/efi and still work?

Why would I try it? I am not suggesting that it would work. After you emerge elilo or grub2 you are still not able to boot unless you do other steps (grub2-install or cp elilo.efi /boot/efi... && efibootmgr ... etc.) > > What exactly is the issue you are trying to solve here? I am thinking about creating ebuild for shim. I was wondering if there is any policy or suggestion where to place .efi binaries or how to handle them in gentoo - it seems that there is none so perhaps there should be agreed on what best practice is (install directly into /boot/efi or install else and let user manually copy .efi to /boot/efi or something completely different (eselect efi ...)).
In suse default path is for example /usr/lib64/efi/: ls /usr/lib64/efi/: MokManager.efi elilo.efi shim-suse.efi shim.efi xen-4.2.1_02-0.7.2.efi xen-4.2.efi xen-4.efi xen.efi yet /boot/efi contains only elilo.efi > > thanks, > > greg k-h > thanks Martin
