Hello,

I came across the same problem and made a workaround by declaring a
variable EFI_PART_NUMBER and assigning it the partition number of the
EFI partition (in your case EFI_PART_NUMBER="1"). Then I have a script
like this:

if [ $action = "install" ] || [ $FAI_ACTION = "install" ]; then
        [ -r /tmp/fai/disk_var.sh ] && . /tmp/fai/disk_var.sh
       
        umount ${target}/boot/efi
        sgdisk --typecode=${EFI_PART_NUMBER}:ef00 $BOOT_DEVICE
        mount ${BOOT_DEVICE}${EFI_PART_NUMBER} ${target}/boot/efi
fi

This assumes that the EFI partition is mounted unter ${target}/boot/efi,
which it normally should be. From looking at your disk_config, I guess
that currently you do not mount it at all. This won't work either, grub
and its scripts (namely update-grub) rely on the EFI partition being
mounted there.

Bye,
