~/.config/emacs/init.el is best, but *if you have a .emacs.d or a .emacs,
it will not be read*, so you need to do this:

  mv .emacs ~/.config/emacs/init.el
  mv .emacs.d/* ~/.config/emacs

(careful your .emacs isn't overwritten with .emacs.d/init.el when using
these commands)

All the GNU mailing lists can be found here:

[list of GNU lists] <https://lists.gnu.org/archive/html>

It shows that a help-gnu-emacs mailing list exists:

Probably because you already have a .emacs. Emacs prioritises reading the
.emacs file over .emacs.d/init.el, and .emacs.d/init.el over
.config/emacs/init.el. If you want to use .emacs.d/init.el, you need to
make sure there's no .emacs.

You don't want to do that. It's an autogenerated file, and you should
keep those in separate files, in my opinion, so that you don't
accidentally modify things that should not be modified :)

That's why I use this code to redirect all custom customisations into
~/.config/emacs/custom.el:

  (setq custom-file
        (concat (or (getenv "XDG_CONFIG_HOME")
                    (concat (getenv "HOME") "/.config"))
                "/emacs/custom.el"))
  (load custom-file)

Yes, it was. If you decide to do the custom-file redirection above,
you should move this code into ~/.config/emacs/custom.el.
