I am having some strange difficulty formatting a GPT partition within Sculpt

Hi baconicsynergy,

I'm not an expert regarding this, but it seems that the Sculpt Manager
doesn't expect more than 9 partions on a disk. In
repos/gems/src/app/sculpt_manager/model/storage_device.h, in the
part_block configuration in line 228, it generates policies for
partition labels 1-9. This is why your part_block rejects the mke2fs
session request for the partition with "no policy defined for label
'12'". Consequently, your mke2fs dies with "Block-session creation
failed" and "No such file or directory".

I created a quickfix on my branch
https://github.com/m-stein/genode/tree/sculpt-21.03b-baconicsynergy.
Could you give it a try? I hope this is the only place where the Sculpt
Manager assumes such a limit. Maybe we should come up with a more
generic solution to this problem.

Cheers,
Martin
