>Description:
When trying to install gpt on a disk that has been formatted with an Apple, it 
fails. It will always complain about the device being busy when trying to 
create a filesystem, because you have still wedges underlying.
Killing them with dkctl, installation finishes.
>How-To-Repeat:
Put a gpt and some partitions on a disk, try installing NetBSD.
>Fix:
Perhaps delete all wedges present on a disk prior to partitioning? The mbr 
compatibility stuff won't be touched by that anyway, and existing gpt will be 
overwritten.
