In short, I do not like people asking this kind of question to casually install mixed archive for their sake. Especially things like experimental. > I'd rather find out that the above Preferences are destructive here than > during an install! Your setting will install latest experimental of a package which you insalled from experimental. I see no reason to have stable or volatile when you are basically tracking testing or unstable. 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. Even more problems will arise if multiply distribution releases are mixed without a good understanding of the following paragraphs. You have been warned. (Hmmm... s/multiply/multiple/ .. time to make another bug report.) > My ego may be the more delicately balanced but my system is the more > precious. :) This squeeze testing cycle has been rough because of major transitions. My recent upgrade in one of the multiboot setup from stable to unstable caused unbootable system. If your ego ticks you, testing only (or with testing security if available) is good idea. If something broke, add unstable while keeping testing as default (higher preference) to get fixed packages. Right now, stable and testing have too much gap usually to be useful. I would rather rely on my local package archive under /var/cache/apt/packages/* for recent but working packages. (experimental's preference is set to 1 with reason.)
