Duplicating the dbf and connecting it (with v.db.connect) to another
layer, does not create any features on that layer. To do that, you have to
assign category values to features in that layer, with either v.category
or v.digit.
I think there is still a need to a much clearer and more detailed tutorial
on layer handling, as this keeps popping up...
