And apparently it's not a critical thing that prevents users from using Gentoo in practice. 2) A cleanup tool at best will only tell you which files you need to check, randomly deleting files with orphaned uids/gids is not a good idea. 3) This proposal strictly increases the quality of Gentoo. Don't let perfect be the enemy of the good. The fact that the problem isn't solved to 100% doesn't mean that a solution that gets us there 85% should be rejected. Strongly vote +1 to merge this now.
