+# exercise parted's gpt-rewriting code
+# When it encounters a GPT device with backup not at the end,
+# parted (without -s) offers to correct that by moving the backup
+# header to the end of the device.  Before parted-3.1, when it attempted
+# to do that, starting with a 9-PTE array, it would render the result invalid.
