So ideally when I set up a new computer, I want all the users I trust — including, by necessity and regrettably, myself — to be in the staff group, and all the files they create to be by default writable by anyone in that group. This ought to be easy, and in fact now is, but has changed repeatedly over the decades I've been using Debian GNU/Linux, so I can never remember how it's done, hence this note.
