Original bug report:

  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=891063

In summary:

Just after one logs in, does a "su" and runs Emacs, Emacs writes
dconf files in a non-root user's /run/user/XXX directory (related
to DBUS_SESSION_BUS_ADDRESS or XDG_RUNTIME_DIR). I got:

zira:~> ll /run/user/1000
total 0
srw-rw-rw- 1 vinc17 vinc17   0 2018-02-22 04:02:21 bus=

drwx------ 2 root   root    60 2018-02-22 04:02:32 dconf/
             ^^^^^^^^^^^
drwx------ 2 vinc17 vinc17 140 2018-02-22 04:02:21 gnupg/

drwxr-xr-x 2 vinc17 vinc17  80 2018-02-22 04:02:21 systemd/

Unsurprisingly, this then yields issues when one runs Emacs
as a normal user:

(emacs:8958): dconf-CRITICAL **: unable to create file '/run/user/1000/dconf/user': Permission denied.  dconf will not work properly.
[...]

Emacs should never create files/directories if the user hasn't
explicitly asked it to do that, in particular if this is under
a directory owned by a different user.
