This chapter presented the basic concept of packaging, a concept that has a central role for Poky and BitBake; package versioning; and how this impacts Poky's behavior when rebuilding packages and package feeds. It also showed us how to configure an image to be updated using prebuilt packages provided by a remote server.
In the next chapter, we will learn about the BitBake metadata syntax and its operators to append
, prepend
, and remove
content from variables, variable expansions, and so on. We will then be able to understand the language used in Yocto Project engines better.
