bootdevs look for a 'boot<arch>.efi' on each filesystem

I don't want to make this bootmeth obsolete. What is the motivation for that?
This method was written in a way that per se violates the UEFI
specification as it does not set up required UEFI variables.
You must never run this before the boot manager as booting
EFI/BOOT/BOOT<ARCH>.EFI if there is a boot option violates the UEFI
specification-
The boot manager covers the functionality of this bootmeth.
Best regards
Heinrich
