Suppose that I have enabled Experimental in my "/etc/apt/sources.list". When I need to install anything from it, I have to explicitly specify on the command:
apt-get install wajig # vs apt-get --target-release experimental install wajig
Where is such a setting stored? I expected that it would be some sort of pinning, but I can't find anything suggesting such in "/etc/apt/". Also, is it possible to avoid the behavior?
