Tryton has modules and without any module packaged, it will do nothing

But at least you can launch it and test it, you can use it for packkaging the missing modules.

Also a service would be useful. But in order to write a service, the server packkage has to be in already.

This is supposedly the basis for GNUealth, a notable GNU project

Gnuealth is a collection of Tryton modules and some specific Tryton configurations. I just have to check if the versions are compatible
