I do not understand why I should depends on the server-core.

I do not want to nistall a running (or not runing) server on the machine where I install the tango-db service.

I understand that I need to have a working client in order to be able to connect to a remote server which is running.

In the case where I want to install the server with tango-db on the same machine.

In fact I wan t to support both scenario

1) tango-db + [mysql/mariadb]-server on the same host -> Pre-Depends default-mysql-server

2) tango-db + [mysql/mariadb]-server on different hosts -> ?

Maybe the solution would be to have different tango-db package for both scenarios.

Are you aware of other packages with this kind of needs ?

I will try to find a reference.
