Hmm, I'm not at all a git expert, but I thought common practice was to 
clone the upstream git tree, then create local branches that track the 
upstream ones. I've never seen any directions say "first create a bare 
clone, then clone that again, then create local branches."

The docs don't cover "how do I add a kernel patch?" at all, AFAICS.

... oh wow, now I see 
http://www.yoctoproject.org/docs/current/dev-manual/dev-manual.html. 
This actually does talk about bare clones. 
http://www.yoctoproject.org/docs/current/kernel-manual/kernel-manual.html, 
which is what I had been reading, does not.

The reason I'm even bothering is to try to be a good person. I could 
have stuck this in a private collection 2 days ago... but I figured this 
is going to bite plenty of other people, so I should try to submit a 
patch that would fix it for everybody. I could tell the kernel 
configuration system is complicated, but I really didn't expect this 
many barriers.
