hi,

with the actual GIT version i was able to create a SLES12 based EFI boot iso image, but the first
boot option (Relax and Recover (no Secure Boot)) does not work, the generated grub.cfg
looks like:

menuentry "Relax and Recover (no Secure Boot)" --class gnu-linux --class gnu --class os {
echo 'Loading kernel ...'
linux /isolinux/kernel [..]

The "Secure Boot" option however works, difference is that this one uses "linuxefi" instead
of "linux":

menuentry "Relax and Recover (Secure Boot)" --class gnu-linux --class gnu --class os {
echo 'Loading kernel ...'
linuxefi /isolinux/kernel [..]
