Well, I can't do that because 'gvinum create'  panics even if the new drive
is named differently. Perhaps the problem is using the same device which was
once already present, and that's why I need to remove all objects first...
The fact is I can't remove the objects with the system running, and once
they are removed, there's no need for a different name. Actually, it's
easier to use the same original create script...

I'll try to apply your patches and see if it this issue is solved.
