All of my production systems run kernels with hard-wired device
assignments. No, it's not ideal, but it's better than risking some kind
of hardware failure cascading into something even more damaging.
Hard-wiring device assignments in the kernel forces the driver
autoconfiguration code to fail safely. I'd rather have the user-land
naming scheme always relate in some fixed way to the hardware (eg. in
the way SunOS-5.x and its ancestors do), but that's not even always
possible on some architectures.
