What I envision is adding an append statement of some kind to local.conf to load in the wireless related files to core-image-minimal, same with openjdk-7-jre and tomcat7, but my first efforts have generated some unintelligible error for me.  So that’s why I’m looking for direction on where to start with this.

Okay, what I don’t get is the fact that without any additional layers, bitbake core-image-sato builds all the WiFi features I need.  bitbake core-image-minimal does not.  So I’m thinking that there is some CORE_IMAGE_EXTRA_INSTALL statement that can just add what is needed without extra layers.  

I guess it just doesn’t make sense to me right now.
