It won't, however, do housecleaning of packages in separate slots which are not used. To do that: #usually required to make the next step happy emerge -uDN world emerge -p --depclean Make sure you have the -p option, and sanity check the output of --depclean. It's almost always correct, but only almost. See man emerge for more information on other useful things the --depclean can do (in particular, it does what most people seem to think 'equery depends' does). Nick
