IIUC we need to monitor for a "backup hint", spawn the master, rename it to maintain backwards compatibility with no-VF setups and enslave the VF if it appears. All those sound possible from user space, the advantage of the kernel solution right now is that it has more complete code. Am I misunderstanding?
