I have read through bug 370295 and understand that editors in @world are prioritised. However when examining virtual/editor as suggested in that bug $ portageq expand_virtual / virtual/editor app-editors/nano nano is the only one returned, whilst emerge --depclean -p returns the following >>> These are the packages that would be unmerged: !!! 'app-editors/nano' (virtual/editor) is part of your system profile. !!! Unmerging it may be damaging to your system. app-editors/nano selected: 2.3.1 protected: none omitted: none If I understand correctly, this would leave me without an editor and is not the expected result?

You must have another editor installed, or else --depclean would not remove app-editors/nano. The portageq expand_virtual function is only supposed to return the provider that is preferred according to the dependencies of virtual/editor. Since app-editors/nano is leftmost in the dependencies of virtual/editor, that is the one that is returned. If you uninstalled app-editors/nano, then the portageq expand_virtual would return the other editor that you have installed. The bottom line is, if you use app-editors/nano then you should add it to your world file, like this: emerge --noreplace app-editors/nano If you don't use app-editors/nano, then you can safely remove it. Just make sure that you have some other console mode editor installed, such as app-editors/vim or app-editors/emacs.
Sorry I was confused by Comment 2 on Bug 370295 with regards to the function of portageq expand_virtual / virtual/editor However, I do not seem to have another editor installed as eix only returns one result $ eix -I -C "app-editors" [I] app-editors/nano Available versions: 1.3.12-r1 2.0.9 2.1.10 2.2.5 (~)2.3.1 {debug justify minimal ncurses nls slang spell unicode} Installed versions: 2.3.1(10:01:35 12/05/11)(ncurses nls spell unicode -debug -justify -minimal -slang) Homepage: http://www.nano-editor.org/ Description: GNU GPL'd Pico clone with more functionality I have no problem with running emerge --noreplace app-editors/nano I felt it was a bug within emerge --depclean that it would leave me without a editor installed?
(In reply to comment #2) > However, I do not seem to have another editor installed as eix only returns one > result > > $ eix -I -C "app-editors" Your query is incomplete, since some editors exist in other categories. For a complete list, run portageq metadata / ebuild virtual/editor-0 RDEPEND": || ( app-editors/nano app-editors/dav app-editors/e3 app-editors/ee app-editors/efte app-editors/elvis app-editors/emacs app-editors/emacs-vcs app-editors/emact app-editors/ersatz-emacs app-editors/fe app-editors/gvim app-editors/jasspa-microemacs app-editors/jed app-editors/joe app-editors/jove app-editors/le app-editors/levee app-editors/lpe app-editors/mg app-editors/ne app-editors/ng app-editors/nvi app-editors/qemacs app-editors/teco app-editors/uemacs-pk app-editors/vile app-editors/vim app-editors/xemacs app-editors/zile app-misc/mc[edit] dev-lisp/cmucl mail-client/pine sys-apps/ed ) Maybe you have sys-apps/ed installed. There reason that emerge still warns is that you may not even be aware which other editor you have installed, or you may prefer app-editors/nano over the other editor that happens to be installed. > I have no problem with running > > emerge --noreplace app-editors/nano > > I felt it was a bug within emerge --depclean that it would leave me without a > editor installed? It's a property of the system set and virtual/editor, rather than emerge --depclean. It's important for emerge --depclean to eliminate redundant package whenever possible, since this allows automatic resolution of blockers in cases where two redundant packages block each other (see bug 264434).

Zac, many thanks for your patience and explanations, I found sys-apps/ed on my system
