That is what I thought as well then I immediately thought about how the people who make custom Android ROMs (and Windows PPC roms before that) are known as 'Chefs' because they are cooking together all of the different pieces that make their ROM unique. No different than someone cobbling together a linux distribution but Jonathan Carter, of Debian, isn't referred to as a Chef. The title should read though, "Cofounder of Chef on Centos being open source." Chef, like Puppet, is used to manage server configurations.
