I like idea of that. Few days ago one developer asked me how to prepare rootfs 
with all debug symbols so he could use gdb-cross/gdbserver combo to debug 
something on device. With this code I can just generate normal + debug rootfs 
in one go (bitbake bug-image-production bug-image-production-debug).
