From 721215403790283447b101652e80c1ef766f4611 Mon Sep 17 00:00:00 2001

Subject: [PATCH] refactor: split ReceiveServerConfig handler

First handler, with original name, validates the server config.

The new second handler, ReceiveValidServerConfig, can then (re)start the
server without needing to validate the settings.
