It appears that the reason for the issue is that the EFI file is
identical on both targets. Could this behavior actually be considered a
bug? Consider the scenario of a multi-disk system; have you attempted to
remove one of the disks and observe the boot process to determine if the
duplicated EFI file is causing unexpected behavior?
