Packages are critical to Poky as they enable the build system to produce different types of artifacts, such as images and toolchains.

A recipe may generate one or more packages as a result of it being executed by BitBake. On the other hand, images and toolchains are made of several packages that are unpacked and configured to accomplish the intended goal. The generated result is wrapped in such a way that it can be installed into one or more images, or it can be deployed for later use.

List of supported package formats

Currently, BitBake supports four different package formats:

RPM: Originally named Red Hat Package Manager (RPM), but now known as the RPM package format since its adoption by several other Linux distributions, it is used by popular Linux distributions such as SuSE, OpenSuSE, Red Hat, Fedora, and CentOS, among others.
