As I said I would, I put the contents of /boot onto the FAT-formated EFI partition. This is suboptimal. The default is to use "kernel.old" ... etc ... which cannot be done on a FAT partition... at least not with our filesystem driver ... ... but with all of /boot on the EFI partition, simply starting loader.efi works.
