Comment:
Correct configuration of D-Bus is not an easy task, information are not very clear and in some case in contradiction this is true in every distribution not only in void, for example look at this long mail from debian mailing list https://lists.debian.org/debian-devel/2016/08/msg00554.html

In my opinion Void D-Bus documentation doesn't provide enough information about how an user have to correctly start an user session bus.
I've taken inspiration from kde, https://github.com/KDE/plasma-workspace/blob/af44f2cc79fb816e31ea125141e75abb66320602/startkde/plasma-dbus-run-session-if-needed, and now I'm starting my sway with a wrapper script, `/usr/bin/sway-run.sh` with this content:

 ```
#!/bin/sh

# Session
export XDG_SESSION_TYPE=wayland
export XDG_SESSION_DESKTOP=sway
export XDG_CURRENT_DESKTOP=sway

# D-Bus
# If the session bus is not available it is spawned and wrapper round our program
# Otherwise we spawn our program directly
drs=
if [ -z "${DBUS_SESSION_BUS_ADDRESS}" ]
then
    drs=dbus-run-session
fi

# Environment
# Imports sway desktop enviroments
set -a
. /etc/sway/env
set +a

exec ${drs} sway "$@"
 ```

So having some examples on how to start a dbus user session will be very nice.

Another idea would be to have some sane default configuration for window manager in addiction to the standard one, for example add the sway wrapper script so a medium user can easily start a sway session but advanced user can start sway session as he likes.
