The latter. Layouts are loaded successively: First, the document class 
layout; then the modules; then the local layout. Each one can either add 
to or over-write previous settings. This technique is used in many of 
the document class layouts themselves: They import 'standard' settings, 
then modify what needs modifying.

That's the way to do it.
