grub-install always uses /boot/grub if you don't use --root-directory=
option, else it uses ${root-directory}/boot/grub
The device you give it is only for the MBR/boot sector code and the
embed copy of core.img if there's space to embed it. But the file which
gets embed also gets first created in /boot/grub.

The grub-pc package runs grub-install on the devices which are stored in
the debconf database for it.
If you want to change/disable that one, then run `sudo dpkg-reconfigure
grub-pc'
But as I just replied to #495423, disabling it can make your system
unbootable if the package gets upgraded and update-grub generates a
grub.cfg which isn't anymore 100% compatible with the older GRUB 2.
