I've also heard about the idea of 'Library Cookbooks', and the idea of having a generic cookbook that you can include in an organization-specific cookbook seems very intriguing. If you are familiar with this concept, including it the book would be quite worthwhile.
Another area I would be very interested in is Chef Best Practices. I've gotten myself into quite a bit of trouble by putting way too much information in my roles, only to run into all sorts of trouble with versioning when working in multiple environments i.e, 'dev', 'test', 'prod'.
Anyway, thanks for putting in the effort to get a book out. Chef is a little starved in the way of accessible information (I shouldn't have to resort to IIRC multiple times per day to get questions answered). This is badly needed.
I think i'll add a section that goes over the process as you say, because once the framework is set up you could
-create cookbook -build tests -write book -verify quality -test on vagrant -version/promote
something like that.
