Trond, thanks for the enlightenment, I think I grasp the idea. Two
more questions if you please:

1. If I have more than one freebsd-ufs partition, how can I configure
boot1.efi (AKA /EFI/BOOT/BOOTX64.EFI) to boot the loader from a
particular partition, not from the first one?

2. Why are /boot/boot1.efi and /EFI/BOOT/BOOTX64.EFI (extracted from
boot1.efifat) so different, even different length? They are supposed
to be one and the same file, aren't they?
