I know Packt was looking for a Chef author a few months ago. I declined to work with them, but I'm working on an outline for a Chef/DevOps book to self-publish.
I'm surprised I didn't know that; they've invited me to write a book on nearly every other technology I listed on my linkedin profile. :-/
That's why I don't buy books from Packt unless I can find good reviews of it written by members of the community around the software the book is about.
PostgreSQL 9.0 High Performance is a Packt book with excellent content, but it has multiple typos and grammar errors on every page. I'm sad to see such an outstanding book marred by bad editing.
I'm a friend and former colleague of the author, and having read the book from cover to cover I don't think it's true that it has lots of typos. I think you might be confusing it with another title.
