This allows using the same code to create the initial configuration and upgrade configurations on upgrades.
* If it is unavoidable to run different code during the initial installation, the ``sysconfig.gluon_version`` variable
can be checked. This variable in ``nil`` during the initial installation and contains the previously install Gluon
can be checked. This variable is ``nil`` during the initial installation and contains the previously install Gluon
version otherwise. The package ``gluon-legacy`` (which is responsible for upgrades from the old firmwares of
Hamburg/Kiel/Lübeck) uses the special value ``legacy``; other packages should handle this value just as any other
string.
