Hello Josselin,

I should have been more clear with my last message. Indeed I would be
able to add the additional config values to the service. I haven't done
so because I was told in order to get a service merged into Guix, one
has to provide a "test marionette" (I don't even know what that is since
it's not documented in the manual).

That's what was holding me back. But if that's not the case I'll gladly
submit a patch in the upcoming days.

Best regards / Mit freundlichen Grüßen,
