Aha. That is interesting, since if the file wasn't found, you should
get a fetcher error. But if the file isn't in the workdir, then it 
definitely
won't be tacked on the end of the configuration for you (as you've
seen).

So that brings the question back to the bbappend, and why wouldn't your
file be found and propagated. hmm. I can always try something here, but
I've had multiple bbappends in the past and they've worked .. but one just
never knows what can silently break.
