 The only thing I'd suggest, after some more thought, is to remove --efi-directory and just use the install_device (the non-option arg given to grub-install) as the EFI directory -- this is also most-consistent with the usage a user might expect (IMHO).

The --efi-directory option does same thing as --root-directory option for specifying mountpoint of UEFISYS partition. At first I thought grub-install now allows specifying the EXACT directory where all the files aka grub.efi , *.mod and grub.cfg should exist.

From my understanding of how grub-install works, if I specify

--efi-directory=/boot/efi --bootloader-id=grub2

grubx64.efi is installed at /boot/efi/efi/grub2/grubx64.efi ,  but the modules are located at /boot/grub (which is $grubdir aka prefix set in grubx64.efi/core.efi). But this again creates confusion for some users who have to find out the "actual" prefix dir in case he/she wants to modify grub.cfg and grubenv in that dir. The only way to force grub-install to install "everything" in /boot/efi/efi/grub/ is to use

--efi-directory=/boot/efi --boot-directory=/boot/efi/efi --bootloader-id=grub

Even if I use

--efi-directory=/boot/efi --boot-directory=/boot/efi/efi --bootloader-id=grub2

I get /boot/efi/efi/grub/{core.efi,*.mod} and /boot/efi/efi/grub2/grubx64.efi . Is there any option to specify to exact dir (both for grub-install and grub-mkconfig and other related scripts which use --boot-dir and --root-dir)?

I don't know whether it is okay to compare grub2 with syslinux, but extlinux provides --install option to specify the directory where ALL syslinux related files are present, no --root-dir , --boot-dir , --bootloader-id confusion. I want all files under one dir (/boot/efi/efi/grub2, not referencing to /boot/grub or /boot/efi/efi/grub). Thanks in advance.
