It does not look right: 
linux:/usr/lib/python2.4/site-packages # smart install alsa --dump

It shows the packages to be installed and to be removed, without being 
able to distinquish between both.  If the to be removed package is not 
shown, it might be okay. 
 
But the --dump is especially useful for the upgrade (dist-upgrade if it 
exist) option.  So please add it to the upgrade action too.
