Comment 9 for bug 1316978

I just felt the need to point out that unity8 doesn't really even use HUD any more (as of a week or so ago, the gesture to invoke HUD was disabled).

So if HUD failing to load due to DBus failure blocks unity8 startup, we could probably just cut a few more cords in the unty8 codebase to prevent the HUD UI component from attempting to initialise HUD. Either by deleting the UI components, or by ensuring they don't load.
