That implies that "grub-install /dev/sda" or, in the case of a non
chrooted LiveCD/USB environment, "mount /dev/sda1 /mnt/ &&
grub-install ---boot-directory=/mnt/boot/" is complicated. I can't see
how it could be made more simple, as the two pieces of information
passed to grub-install, where /boot/grub/ can be found (if not at
/boot/grub/) and where grub's boot sector should go, are both
necessary. When there is no boot sector, like with UEFI systems, as
long as the EFI System Partition and /boot/grub/ are mounted properly
the command is only "grub-install" with no other arguments. That seems
as simple and minimal to me as a bootloader installation can be. Can
you propose a simpler command?
