The wiki is allowed to be tragically wrong every once in a while. :) From emerge(1), we see: --oneshot described as, "WARNING: This option should only be used for packages that are reachable from the @world package set (those that would not be removed by --depclean)," --depclean described as, "Depclean works by creating the full dependency tree from the @world set, then comparing it to installed packages. Packages installed, but not part of the dependency tree, will be uninstalled by depclean." And of course under "set A set is a convenient shorthand for a large group of packages.", we see, "while world encompasses the selected, system and profile sets." No "that is to say", just a technical definition. Actually the same one in the wiki *before* the "that is to say". The "that is to say" explicitly contradicts the previous sentence: "The @world set is the largest superset on a Gentoo system: a union of @selected, @system, and @profile sets." Because "all packages installed on the system" includes dependencies that are not in either of the 3 items the union consists of. They are *installed*, but neither *selected* nor system/profile. Suggestions for better wording for the wiki? "installed" is wrong, "explicitly installed" only applies to @selected as one doesn't explicitly add @system/@profile to @selected-sets or anything, "all packages not eligible for depclean" is accurate but not in theme, "all required packages for the system" feels clumsy. -- Eli Schwartz
