There's problem for new hardware. Minimimal install iso successeful booted from new only EFI hardware, but kernel hasn't worked efivars module. This problem available only for minimal install iso: for livedvd hardened or not this module is available. Reproducible: Always
The minimal installcd has EFIVAR_FS (efivarfs module) which is considered to be the replacement for EFI_VARS (efivars module). Do you specifically need this older one? You should have /sys/firmware/efi/efivars/ populated, which all modern tools can use. The old module provides /sys/firmware/efi/vars/ which shouldn't be needed.
EFIVAR_FS efivarfs is a replacement filesystem for the old EFI variable support via sysfs, as it doesn't suffer from the same 1024-byte variable size limit. To compile this file system support as a module, choose M here. The module will be called efivarfs. If unsure, say N.

This module not loaded and failed to loaded throw modprobe. Maybe I wrong. But I couldn't install gentoo from manual on newest hardware.
What error did you get when you tried to install?
(In reply to Ben Kohler from comment #4) > What error did you get when you tried to install? Than I run grub-install from minimal-sd I have message: EFI variables are not supported on this system.
I don't think you're booted in EFI mode, does /sys/firmware/efi exist and have stuff in it?

It will exist if you boot the minimal installcd in UEFI mode as well. Note that only minimal installcds built in the last few days will have UEFI support, it was JUST added.
