Summary
In this chapter, we covered how to create a new layer and metadata. First, we saw how to create a machine configuration, a distribution definition, and recipe files. Then, we learned how to make images and include our application in an image.
In the next chapter, we will access some examples of the most common customization cases used by an additional layer, such as modifying existing packages, adding extra options to autoconf, applying a new patch, and including a new file to a package. We will see how to configure BusyBox and linux-yocto, the two packages commonly customized when making an embedded system.
