In spite of there being considerable documentation sometimes in the
config file, we go with CC0 because we don't want the notion of
'derived work' of a config file.
The example `settings.conf` is also CC0. Add some docs to
it while we're at it.
- Improve documentation of the settings
- If sysconfigSetup is true, **only** setup sysconfig and ignore
the rest. This seems to be consistent with existing openSUSE-
derivative distro's, which set displaymanagers to something
nonsensical.
Do not use a YAML list when only a single entry actually works. (It was
just silently using the last one.)
Create the default_desktop_environment DesktopEnvironment tuple. Before,
the setting was silently ignored altogether.
