I think it would be even more confusing, because that file isn't even editable. So you'de get users thinking they must re-install the distro to change that file.

Others would eventually find /etc/config.scm and not pass it as argument, then get their system reconfigured to something different than what they specified.

Maybe it should be "e.g. /etc/config, initially generated by the graphical installer" or something?
