This shows a preliminary idea on how the SUMA requirements could be addressed reusing a lot of code from the current partitioning proposal and from the current Guided Setup.
In the control file, we just need to add a new attribute to identify volumes
that must be allocated in its own separate LVM VG. The rest of the
<partitioning> section of control.xml would stay as it is now.
And then, the new wizard would reuse many of the steps already present in the current Guided Setup.
