Comment 19 for bug 967229

So I've had a look at trying to start plymouth before lightdm has shutdown, in order to start capturing console messages sooner. Unfortunately this doesn't work right, lightdm shutting down puts the VT into a state that lightdm isn't expecting so the splash doesn't update the screen correctly.

I don't see a way to fix this reliably with the current architecture. We could fix individual messages that are being output, but unless there's some way to get the output redirected to plymouth before lightdm stops, there's no way to ensure a completely text-free shutdown without causing very problematic knock-on effects.
