"su -l" is not a solution as it reset the current working directory. And one should still be able to run X applications after su. It could be a bug in su, which doesn't clean up enough by default: it does for HOME, and XDG_RUNTIME_DIR is in the same class. But in any case, emacs shouldn't create files/directories if the user hasn't explicitly asked it to do that. Note that I haven't even tried to change the config from Emacs. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
