This is likely a dumb/obvious question but do you need to be booted in 
uefi mode for the the install to use uefi?
I don't have a /sys/firmware/efi or a /target/sys/firmware/efi during 
the install.  I had thought there was a way to tell FAI to configure the 
boot on the target for uefi regardless of what FAI is running in.

In looking at grub-install it also looks for /sys/firmware/efi.
