When you use 'grub-install /dev/sda' you are telling GRUB to install
into the boot sector of /dev/sda and put core.img into a post-MBR
portion of the disk. The boot block knows where the first sector of
core.img is and core.img can search for and find the configuration. I
don't think GRUB uses system device names to do any of this when booting
the OS.

No tricks needed as far as I am concerned. You maybe have to realise
that --boot-directory needs a grub.cfg as one of its contents but, as we
hope roberto has discovered, update-grub takes care of that.
