-# <Ganneff> are we going the xorg way?
-# <Ganneff> a dak without a dak.conf?
-# <stew> automatically detect the wrong settings at runtime?
-# <Ganneff> yes!
-# <mhy> well, we'll probably always need dak.conf (how do you get the database setting
-# <mhy> but removing most of the config into the database seems sane
-# <Ganneff> mhy: dont spoil the fun
-# <Ganneff> mhy: and i know how. we nmap localhost and check all open ports
-# <Ganneff> maybe one answers to sql
-# <stew> we will discover projectb via avahi
-# <mhy> you're both sick
-# <mhy> really fucking sick
