Hi, For all I know, debconf database is supposed to store "answers" to configuration parameters of packages. But when you install operating system, you aren't given an opportunity to specify them. Not all of them at least. There are a bunch of them in /var/cache/debconf/config.dat.
So where do all of them come from? Does debian comes with default config.dat? Does it contain values for all the packages? For some predefined set of them? Which package owns it? Or generates? I've run into it trying to set up lxc container. There where differences between releases. So I started to dig into where they're coming from. The issue was with resolvconf package and resolvconf/link-tail-to-original parameter. Regards, Yuri
