apt-pinning and 'aptitude safe-upgrade'
Hello, i have never used apt pinning but decided to give it a go today. I am running Squeeze, and am trying to apt-pin one program from testing. When i go aptitude safe-upgrade before installing the program, just to make sure it's working like desired; it says i have x amount of upgrades and would i like to proceed. I know that these upgrades aren't coming from the stable branch because when i have the testing repo commented out, update my sources, and try i have no updates.
Is this normal behavior, or have i obviously reconfigured something?
