Having the grub directory on the external device is not what I'm looking

I indeed use several external devices and I've installed GRUB on each of
them so that it is always available, whatsoever my configuration is. To
avoid confusion when updating GRUB, all my fstab files mount a unique
directory, always the same, on /boot/grub. This is the reason why I want
GRUB on my hard drive.
