Can an option to grub2-install be added that installs only to /boot/grub2 and creates core.efi, but does *not* write into the ESP? This would provide similar functionality to the --no-bootsector option used in PC-BIOS systems for using a Master grub partition that chainloads into multiple operating systems.
