I just installed jessie and several packages. Then I go to my '/etc/apt/sources.list' and I see that it's tracking testing! I want stable! Thing is that I've already done a 'dist-upgrade' and I know that it is reckless to downgrade. Now, is it possible to do a 'wait for stable to catch up to testing otherwise leave well enough alone' sort of thing? That is, I'd like to edit my sources.list from testing to stable BUT not downgrade anything, merely leave everything alone UNLESS it is upgradable from the standpoint of jessie, that is, can I wait for jessie to catch up yet avoid going backwards vis a vis what I already have? Perhaps there is something like: "apt-get dist-upgrade --no-downgrades"?
