Chapter 4. Adding packages during image creation by Using Red Hat Image Builder

You can customize your images during the creation process by adding additional packages from the BaseOS and AppStream RHEL repositories, through the UI. With that, you do not need to install the desired packages on first boot, which can be error-prone.
