A --depclean would however, Also --update will take a peak att depB while --deep will follow down to depC and depD. If you add the whole system to world a simple `emerge -u world` would have to examine every single package, and its first line of deps, for updates (I don't know it it optimizes away packages that has already been decided on), which would mean that glibc f.ex. would be examined about 400 times, could get rather slow I imagine... /John > > > > Now if you run that script and put *all* your packages in the world > > file then portage won't know if depB can safely be removed because it's > > now a regular package in the world file instead of just being a > > dependency of packageA?
