Subject:[PATCH] pungi: Add support for generating EFI-bootable USB images
From:Matthew Garrett (mjg@srcf.ucam.org)

Right now our hybrid images aren't bootable via EFI when written directly to a USB stick. This patch adds the necessary argument to the isohybrid call, and in addition will perform appropriate setup to make the image bootable on older EFI Macs if the tree has a macboot image. This requires syslinux 4.02-5 or later.
