Indeed there is; assuming you are using the dora (1.5) release or newer, you
can add the debug packages to BAD_RECOMMENDATIONS (since relationships between
-dbg and -dev packages are RRECOMMENDS.) This should also allow you to add
individual -dbg packages back in by explicitly adding them to IMAGE_INSTALL if 
you need to.
