yast2-storage-ng is a reimplementation of the YaST storage module (yast2-storage) based on the also reimplemented library for storage manager (libstorage-ng).
This module includes some working but very limited prototypes capable of actions such as partitioning or proposing a filesystem layout for installation.
The module is entirely unsupported.
If you are brave enough to install this module in a (open)SUSE system, despite the facts that is not supported and can produce data loss, you can perform the following steps (as root):
