Yes, sysinst should not try to find out wether a disk has a GPT by invoking
gpt(8), as that tool is obviously not up to the task.

I would change it to just open the disk, read a few kb and check the GPT
(master copy) signature, but others claim this would violate the UEFI
spec that forces us to check the backup copy.
