I like to have "testing" as my default source with the possibility to install packages from "unstable" and "experimental" except for Shotwell wich I want the "experimental" version to be my default and therefore be notified when Shotwell is updated in "experimental". Is this the correct way to do it in /etc/apt/preferences?
