OK, I didn't realize set root was capable of using UUIDs. I did know that the two root entries were different. I got that mixed up with the search command combined with the root=UUID=... which I think needs initrd. Do I have it right now? Should 'set root' be renamed to 'set grubroot'? I think something like that would prevent some confusion. -- Bruce
