Lets take a look around at other subsystems....
What happens if you hot-unplug a SATA drive?
An MMC card?
A USB device?
A PCIe card?
A CPU?
An SDRAM?
Do you know of any subsystem that tried to keep its configuration
across a hot unplug/plug event? I suspect they all require user space
to take some action to get the newly plugged hardware into operation.
