Today I moved libisoburn to extra repository from community, it's needed for creating efi boot images, mkisofs doesn't support this feature. Next step will be to try compiling and bringing a grub2-efi package to [extra]. Then install media with efi support can be easily created. greetings tpowa -- Tobias Powalowski Archlinux Developer & Package Maintainer (tpowa) http://www.archlinux.org tpowa@archlinux.org
