Comment 17 for bug 109434

I think wesnoth-server shouldn't start wesnothd server automatically at statup. Why so?

Wesnoth client will require wesnothd to be present for some functionality in 1.6 and is already requiring wesnothd in 1.5 development versions. This is only for minor lan game feature.

Solution that I would think of is that wesnothd binary can be installed using package wesnoth-server which doesn't make it auto start.
If someone wants to host MP server that starts always that would be provided by wesnoth-mp-server package. mp-server package would depend on wesnoth-server and only install configurations to run wesnothd at start up.
