It turns out I have an immediate need ;-), so I pushed this as commit
3eee16130d858ae96510ec1c7d38d31290de2699.  Let me know if that doesn’t
seem right!

Now there are things I didn’t quite get.  Apparently you’re supposed to
have a /boot/efi as a vfat partition, and ‘grub-install’ is supposed to
detect it and install the EFI stuff, or so I thought (info "(grub)
Installing GRUB using grub-install").

However, ‘grub-install’ still seems to be installing for “i386-pc”
instead of EFI.

What am I missing?
