Yes, I do that allthe time. I also use it to boot ISO images from DVDs :) > but Gummiboot is less fiddly to set up. Which is why I prefer it. But it is fine to have both installed and available from the UEFI boot menu. I do this on my laptop to make sure I can always boot a rescue ISO if I need to. For my other systems, there's usually a suitable USB stick nearby. > Unfortunately, you can't boot an ISO in true minimalist fashion just by > pointing to it with the EFI boot stub (the ISO needs to be mounted via > a loopback function). I know all that. What would be nice would be an EFI boot stub that took care of that. It occurs to me that the System Rescue Cd kernels may be UEFI compatible, so it may be a matter of unpacking the ISO into /boot to be able to access it from gummiboot/bootctl. -- Neil Bothwick "It compiled?
