Comment 4 for bug 1567194

This isn't actually easy to fix with our current dependency layout -- ubiquity has "Before=plymouth-quit-wait.service" and getty@.service has "After=plymouth-quit-wait.service", i. e. right now we sort ubiquity ← plymouth ← getty. Thus we can't possibly start getty before/with ubiquity, we need to re-think how we insert/use plymouth here.
