Follow-up Comment #8, bug #43653 (project grub):
Another example (to show what a raidz looks like, mirror is probably similar,
my previous example is a single drive pool)

This is not best example since this one is using /dev/sdX for it's members, so
would probably work as-is, but if it was using /dev/disk/by-id it wouldn't, so
just use your imagination. :)
Sadly, my C-fu is too weak to attempt writing any patches myself at the
moment. I haven't done any "real" C programming in probably a decade. I
glanced at the code and the output parsing would need to be rewritten since
the output is in a different format, but if that's done it should be fine.
