 This reminds me ...

 ... it would be also nice to have a way how set partition UUID.
 Currently GPT UUID is always generated. Maybe we will use the UUID
 for some userspace operations (DevKits, udev, mount, ...) and then
 people will look for a way how to control this identifier.

 (Yes, I know that UUID should be unique, but sometimes is it very
 useful to create a new disk layout with the same UUIDs.)

     $ parted /dev/sda part-uuid 89ec2a20-ab3a-4105-b5e8-b141666fbd0c
