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