Comment 18 for bug 1309617

the bridge is suppose to run during startup (boot) and shutdown, when there is also plymouthd running.
However plymouthd can be started from initramfs or via upstart job.
In the case when plymouthd has been started from the initramfs, we can be running the bridge straight away, otherwise it needs to wait for plymouthd to start. The termination messages are from the later case when plymouthd was not started from the initramfs. I wonder how to best minimize impact here, e.g. doing plymouth ping in pre-start. and start on startup or started plymouth.
