Summary

In this chapter, we learned how to customize existing recipes using the .bbappend files and benefited from this by avoiding the duplication of source code. We saw how to enable or disable a feature, how to apply a patch, and how to use the configuration fragment support.

In the next chapter, we will discuss how the Yocto Project can help us with some legal aspects of producing a Linux-based system using packages under different licenses. We will understand which artifacts we need and how Poky can be configured to generate the artifacts that should be shared as part of the copyleft compliance accomplishment process.
