I see what you mean. The --depclean flag (and --unmerge as well) is listed in the section for "action"s. depclean isn't an *option* such as --ask / --color / --jobs / --verbose / etc. And, the synopsis states that all *actions* allow specifying optional atoms / sets / etc at the same time. This isn't clear from reading the individual documentation on an action, but I'm not sure what a solution here might look like. > It could also warn users that their system packages are not protected > against removal in certain circumstances. > > It could correct the error where it says "Packages that are part of the > world set will always be kept.".

Moving beyond that, nano and openrc aren't an *expansion* of @world, but they are an RDEPEND of atoms (virtual/*) that are expanded from @world. The emerge documentation says that packages that are part of the world set -- i.e. they are expanded from @world -- will be kept. It doesn't say that their dependencies will be kept (there are arguments about why this is the portage design, but this discussion is less about whys and more about whether the documentation is correct, so that's what I will address). I don't really see that part of the documentation as being in error. Although I suppose I also don't see any harm in rewording it for additional clarity. I'm not sure exactly how to reword it... -- Eli Schwartz
