Nice :)

Do you need grub2 installed on live-enviroment? In such case we need to
replace grub with grub2.

Do you want to include this tool (efibootmgr) in live-enviroment?

STATUS: Working (1) / Waiting for feedback (2) / Waiting for Linux-3.3
hits [core] (3)

(1) Its works: there is no boot manager, just an efi-shell that executes
an startup.nsh for passing boot parameters to the kernel. Using this
method, at least until EFI_STUB supports linux.conf in mainline, anyway
doing in this way is better because you can "edit" boot parameters.
(2) Such patch increments in 20 MiB each of: netinstall-x86_64,
core-x86_64, netinstall-dual and core-dual. The question is: all these
ISOs should be EFI-enabled for "El Torito"?
(3) Can be pushed now, will boot for EFI, but vmlinuz from [core] is not
an EFI apps, you will get an EFI-shell.

Sure, skip the steps of installing syslinux-mbr, extlinux and marking
partition active, since they are not needed for EFI.

Just unpack <ISO>/EFI/archiso/efiboot.img on <USB-KEY>/EFI and enjoy.
