I suspect it's somehow different because the underlying grub-setup
message was "succeeded in opening the core image but the data is
different" in that one, and in mine, it was just that it couldn't even
find the file.  (I stuck a large number of debugging outputs into
grub-setup to track down the problem).

Interesting, I couldn't test this because it was on a real disk, so
gpt was the only option.  I wonder if it's some sort of "what path
should I be looking for" error with gpt partitions and not msdos ones?
