Wonder if Doug did something similar with src/etc/Makefile.  A simple 
enough change.

The next step would be to advise of cruft left around after turning on 
knobs.  Something mergemaster could be expanded to do.  Shouldn't happen 
automagically.  One can be prompted and have a choice of options or like 
mergemaster currently does for files that only exist in the installed 
system.  A good enchancement and one step closer to a truly modular system.
