Hi Maxime,
Nice idea and viable solution, but here I was talking about the case,
when both home-mcron-service-type and mcron-service-type in the same
(gnu services mcron) namespace. I expect much less confusion and it
probably won't be an issue, when they are in different modules (gnu
home-services mcron) and (gnu services mcron) for example. If person
imports (gnu services SOMETHING) than they expect to get system services
for their operating-system, if they imports (gnu home-services
SOMETHING) they want to extend their home-environment.
