Bug#836102: live-config: please set GSettings using dbus-run-session, not dbus-launch

[Simon McVittie <smcv@debian.org>]

Source: live-config
Version: 5.20160608
Severity: normal
User: dbus@packages.debian.org
Usertags: dbus-launch dbus-launch-for-infra

As described in <https://lists.debian.org/debian-devel/2016/08/msg00554.html>
I'm trying to reduce how much dbus-launch is used in Debian.

This package currently runs:

    sudo -u "${LIVE_USERNAME}" dbus-launch --exit-with-session gsettings set org.gnome.desktop.screensaver lock-enabled false

Instead please use dbus-run-session:

    sudo -u "${LIVE_USERNAME}" dbus-run-session -- gsettings set org.gnome.desktop.screensaver lock-enabled false

which requires dbus (>= 1.8), but does not require dbus-launch or X11.

Thanks,
    S
