This is something I've been aware for some time now, and it also started being a problem for dpkg functional test suite itself, and for the future no-chroot support in dpkg. > I wonder what's the correct way to handle this.

I'm thinking that dpkg should grow a new --confdir option (which I've almost got implemented locally), and --root should also modify that, so that the configuration is taken from the correct place. And the logging directed to the correct destination too. Thanks, Guillem
