+From a7b960126fbc0d4541babe5553546e5f9530ac48 Mon Sep 17 00:00:00 2001

+Subject: Restore grub-mkdevicemap
+
+This is kind of a mess, requiring lots of OS-specific code to iterate
+over all possible devices. However, we use it in a number of scripts to
+discover devices and reimplementing those in terms of something else
+would be very complicated.
