Yep, makes sense.

If I just mcopy -i $@ $(EFI_IMAGE) ::/EFI/Linux/spectrum.efi (explicitly
specifying the destination file name), then it works.  It doesn't  is something like
"/nix/store/3yqb8mfv6skp43yp2r7sn098zrj0hrjf-spectrum-efi".  

This could be avoided by installing EFI_IMAGE to a subdirectory, so the
file name didn't get a hash prepended to it by Nix.  Happy to just go
ahead with changing this and applying my style comments from last
time[1] if you agree.
