Unfortunately it can=E2=80=99t, because there are no UUIDs (that I know of)= to identify drives. However, as the manual vaguely suggests (too vaguely I admit), you can use a GRUB device identifier such as =E2=80=9C(hd0)=E2=80=9D. This is stab= le across reboot, AIUI. I=E2=80=99ve never tried it but if you can confirm that it w= orks this way, we could/should update the documentation to propose that. Thanks, Ludo=E2=80=99.
