Hello,
Currently when installing grub2 on UEFI, the running system's grub2
writes an entry to the ESP making it the controlling grub.
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.
