Packagegroups are divided by functionality level and by features.
The functionality levels start with minimal which includes the bare
minimum packages required for the system to boot. This mainly means
firmwares and drivers.
The base packages include the packages providing basic functionality.
These are usually cli tools allowing access to different interfaces.
The extended packages include advanced tool and services providing full
functionality of the system.
