"The grub part of the bug is that it writes the mbr onto one drive with the first part of the loader which then expects to load the
rest from another drive. If the former is the internal disk and the latter is an external (and therefore not necessarily available)
disk, this is a recipe for disaster."
Full ack. I had that desaster! :-(
Even with both drives internal it jeopardizes reliability, since both drives must be OK to boot.
"I think grub should refuse to write the mbr on a drive which doesn't have the rest of it."
Full ack again.
At least it should write the MBR and the rest of GRUB on both drives and backup to the own partition if the other one is not there. But this might be technically difficult with only that few bytes on the MBR, there is probably no room for two partition tables.
