Ensure that only modules that were turned on in the original config are
turned on in the new config file. When ensuring that the config
dependencies are met, turning on the config options in the new config
leads to warnings and errors later in this script, especially for badly
constructed original config files.
One example could be a config option that is depended on by a module
needed in the new config but is not turned on in the original config
file. If this config needs to be selected, warnings will show up in the
standard output.
