It's impossible to use FAI to install for a platform/system that
requires UEFI because FAI does not currently support setting up a
extended system partition as required by the UEFI spec.
This patch adds code to do that.
I did not update the documentation in this patch, because I'm not that
familiar with all the documentation I'd need to touch.
An example disk_config might look something like:
#
# <type> <mountpoint> <size> <fs type> <mount options> <misc options>
disk_config disk1 disklabel:gpt bootable:1 esp:1 fstabkey:uuid align-at:1M
primary /boot/efi 300 vfat defaults
primary / 300- ext4 rw,barrier=0,noatime,errors=remount-ro
tuneopts="-c 0 -i 0"

Subject: [PATCH] Add support for ESP partitions
UEFI requires a special vfat partition on which the boot loader and
potentially other UEFI information lives. Parted represents this with
an esp flag. Add support for this in setup-storage.
