# This script assumes that the disk has a GPT partition table and
# that the extended system partition (ESP) is mounted on /boot/efi.
# When building a disk image, we don't change the NVRAM to point at
# the boot image we made available, because the disk image is likely
# not installed on the current system. As a result, we force
# installation into the removable media paths as well as the standard
# debian path.
