To me, a knob is always a step backwards, and makes Linux harder to use. The irony in all of this, is that the kernel knows when this stuff is happening. So the ipconfig code should be taught that drivers are still plugging themselves together and probing, instead of setting some arbitrary timeout to wait for these things to occur.
