*Gentle ping* Just wanted to ask if there is anything you wanted me to change. In my opinion, overriding the existing (and required) dbus service with the new dbus-broker is a good compromise or is there an alternative solution you have in mind? (They suggest systemctl enable dbus-broker.service in the GitHub Wiki, which achieves the same thing due to Alias=dbus.service in the [Install] section) If not, I could send an updated version of the patch with v25.
