I'm happily running Devuan Jessie with the fluxbox window manager but no
desktop environment. There is an oddity that causes no problems so far,
but I would like to understand it.

When I boot and before logging in or starting the X server, the boot
message ends with this warning:

dconf-WARNING
failed to commit changes to dconf: Cannot autolaunch D-Bus without X11
display.

D-Dus is automatically launched as part of the boot process. In my boot
log there is:

  Wed Sep  6 16:49:11 2017: [....] Starting system message bus:
    dbus^[[?25l^[[?1c^[7^[[1G[^[[32m ok ^[[39;49m^[8^[[?25h^[[?0c.
  Wed Sep  6 16:51:29 2017: [....] Starting system message bus:
    dbus^[[?25l^[[?1c^[7^[[1G[^[[32m ok ^[[39;49m^[8^[[?25h^[[?0c.

Do if dbus is automatically launched and does in fact get launched, why the
warning that autolaunch failed?

What kind of changes get reported to dbus configuration? And why do they
depend on the X display or perhaps its getting a 0:0 value?

I'm not using systemd, but there are still systemd related files needed
by some functions. Could the warning be an artifact that something is
expecting a real systemd, but it is not getting it?
