how weird disk layouts can become, because GRUB doesn't have to probe

I like this generic approach very much. And as you said, in non-straightforward disk layouts, the responsibility of finding the appropriate path to access a given partition is left to the user.

In all generality, the links between labels is a graph, for instance in your example above, the two occurrences of msdos1 could be the same partition. How does the probing code work regarding this? Does partition_iterate terminate if the graph has cycles?
