Unity Linux itself is not meant to be ran as a full on Linux install, though it can be, it has a very select set of packages and tools for one general purpose and that is to build othera packagescustom live linux distribution. These select packages that Unity includes are tools while core packages are based on [[Mageia]]. Unity Linux's tools can be shared with [[Mageia]] and then utilized by other distribution projects that wish to use [[Mageia]] as a base. So in essence if Unity Linux was to be compared to a physical tree, it would be a trunk that facilitates growth out to the branches, or rather any home based community projects (if any) based on [[Mageia]].
