I have a testing system (with a few items built from unstable sources), and just added unstable to my apt sources.list. As recommended in the HOWTO, I put APT::Default-Release "testing"; in apt.conf. I do not have an apt/preferences file.
When I tried apt-get upgrade (or dist-upgrade) it wanted to upgrade a bunch of packages, all from unstable. I tried commenting out unstable from my sources.list, and apt-get upgrade becomes a no-op. I expected apt would not use unstable unless I explicitly told it to. What am I missing? Many of the packages to be upgraded were from mozilla, which is something I did build from source. So I could sort of see this drawing from unstable, even if I don't understand why. But others are definitely not like that, e..g, gnome-pim, install-doc, openuniverse. As a side mystery, # apt-show-versions -a gnome-pin Not installed No stable version No testing version No unstable version gnome-pin not installed: No available versions But it is installed. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
