"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."
