"WARNING: if for some reason your apt sources doesn't use etch, but "stable" then your apt commands will start to use lenny the moment it is released. This can result in wrongfully performing the upgrade while you don’t want to do this or even upgrade by mistake.We would always recommend people to use the release name (like etch, lenny) instead of generic names (like stable, testing); this way you will have the control on when you want to upgrade."
