grub-install always complains about device.map.  Even if it does a
single-drive install and never relies on any information in device.map,
it still asks the user to check if device.map is correct.  We should fix
it.  Users should not be constantly bugged to check the whole
device.map, only the entries GRUB was relying on, if any.

Better yet, device.map should go away, but not everyone agrees with me.

As I said, GRUB uses its internal ID instead of BIOS ID.  We need to fix
it.  Until it's fixed, cross-device installs are broken, even if
device.map is absolutely correct.

Let's stop discussing symptoms and start talking about the cure.
