Chapter 7. Diving into BitBake Metadata

At this point, we know how to generate images and packages and use package feeds, which is basically everything we must know for simple usage of Poky. Hereafter, we will learn how to control the behavior of Poky to accomplish our goals and take maximum benefit from the Yocto Project as a whole.

In this chapter, we will enhance our understanding of the BitBake metadata syntax. We will learn to use the append, prepend, and remove operators to alter content from variables, variable expansions, and so on. These are the key concepts we can use to make our own recipes and customizations that we will learn about in Chapter 10, Exploring External Layers, Chapter 11, Creating Custom Layers, and Chapter 12, Customizing Existing Recipes.
