Hi, As far as I understand, my text comes from: $ man apt_preferences
Since Bug#1041708 was mentioned, I CC it. I concur more-or-less with what Julian Andres Klode said for the solution. I think what is needed is: by way of being not set up anymore, nor presenting impression of recommendation in release notes. ## Debian Reference As for the entry document such as Debian Reference, I should skip mentioning setting "APT::Default-Release" to whatever since setting it in /etc/apt/apt.conf.d/* tends to cause persistent confusing setting. If someone dare to set such thing, use /etc/apt/preferences with PIN priority. I have such example already with ample warnings. ## man apt_preferences What is written there is 100% correct. But it does create impression of using APT::Default-Release "stable"; as a part of normal system configuration to some readers. I think this document needs to explain apt system functionality thoroughly, dropping use of `APT::Default-Release` reference may not be a option. I propose to replace this line with APT::Default-Release "testing"; I think this don't drive people to set this to "stable" as much. If I go farther, to make deprecated usage of APT::Default-Release in /etc/apt/apt.conf more explicit, I suggest that the following part: Note that this has precedence over any general priority you set in the /etc/apt/preferences file described later, but not over specifically pinned packages. For example, should be changed to something along: Note that this has precedence over any general priority you set in the /etc/apt/preferences file described later, but not over specifically pinned packages. (In order to avoid confusion with /etc/apt/preferences settings, use of APT::Default-Release in /etc/apt/apt.conf is deprecated.) For example, That's my thought on this topic.
