 Yes for the former, but the default should be to support GPT everwhere,
 even if it can not be used for boot disks.

 Interesting idea, I'll check.

 The "clone" functionality is usefull for exceptional cases like when cloning
 a mac "driver partition" or AmigaOS boot parts from one disk to another.
 It takes some space though, so for installers with tight space requirements
 is disabeled via NO_CLONE.
