As I read the man, the 500 setting will respect the target release. Stable: True, and the setting is redundant. If there is no replacement version, stable packages will be left alone either way. Volatile: I was thinking of freshcalm but that setting wouldn't help anyway. > > FYI: > The upcoming apt_preferences(5) manpage (e.g.: apt_0.7.26~exp2_i386.deb) > states: > > Preferences are a strong power in the hands of a system administrator > but they can become also their biggest nightmare if used without care! > APT will not questioning the preferences so wrong settings will > therefore lead to uninstallable packages or wrong decisions while > upgrading packages.

(apt-cacher keeps its cache on a usb drive for my 3 machines. I am archiving versions by not cleaning it until the next release.) In that scenario, I would have gone ahead with an unwise package upgrade and would be retreating to save my arse, er ("down ego, down boy") the system. In which case, I pin the rolled back version to 1001. The preferences file can live on in moderation for the sake of learning. -- Kind Regards, Freeman -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
