5 Debian image guide
As opposed to Yocto, Debian does not provide a completely integrated build experience by itself. Linux kernel and U-Boot
have to be compiled manually and copied to the appropriate directory to be picked up by Debian.
This chapter will go through all neccessary steps, finally building a complete image using the debos Debian image builder. The
result will be a fully-functional Debian Bullseye system.
Alternatively, prebuilt images can be downloaded from https://downloads.theobroma-systems.com/ringneck/ .
Note: While Debian is a great tool for fast prototyping of your product, it is highly recommended to use a distribution/image
tailored to your need. This can be achieved by Yocto (Section 6 Building a Yocto image) or Buildroot for example.

Install packages for compiling the parts and the complete image:
As debos internally uses kvm virtualization, your user must be a member of the
