  and i apologize for beating this so thoroughly -- i'm actually not
suggesting any fundamental changes to the code base; rather, i'm
currently designing an intro course in oe-core/yocto and if i'm going
to use actual recipe files out of oe-core, there's no question i'm
going to have to explain why some of them simply look a bit weird.

  i'm just trying to codify some "best practices".
