My understanding of comment #9 of bug 5239 is that dep-clean is going away? emerge dep-clean only gives part of the information that dep-clean gives.. What's lacking (and that's clearly a portage bug) is that I can't find the new version of the packages that are not in world but dependencies of world. There should be a "emerge -u all" that would not check in world, but check for new versions of all installed packages... I dont see why that would be this hard to do.. Or maybe just check all the dependencies of world/system and check if they are up to date...
emerge -u --deep world Besides that, what does dep-clean have? If there is some userful functionality missing, lemme know.
maybe document the --deep option Other than that.. no I dont see anything.. so I'm closing ;)
A minor quibble, but man emerge doesn't mention --deep at all, although it does seem to work.
