As I was recently looking at lttng-modules, which supports devupstream, I wanted to try to build the devupstream variant. However, neither the information in devupstream.bbclass nor the documentation in the manual were of any help. Since it uses the BBCLASSEXTEND mechanism, I thought it would be as simple as doing `bitbake lttng-modules-devupstream`, but that did not work. So what is the correct way to build a devupstream variant of a recipe?
