You're correct that the dist-upgrade does not do a full upgrade. From
the man page (which we should have read first before hijacking this
thread :) ) :

           dist-upgrade in addition to performing the function of upgrade,
           also intelligently handles changing dependencies with new versions
           of packages; apt-get has a "smart" conflict resolution system, and
           it will attempt to upgrade the most important packages at the
           expense of less important ones if necessary. So, dist-upgrade
           command may remove some packages. The /etc/apt/sources.list file
           contains a list of locations from which to retrieve desired package
           files. See also apt_preferences(5) for a mechanism for overriding
