sysfs -> /sbin/hotplug -> udev

These are all good points, however, isn't sysfs a friendlier solution? 
I'm usually in favor of solutions that are friendlier if all other 
issues are mostly equal.

I'll even go out on limb and wonder if it might even be easier to make a 
new sysfs than it would be to rework sysctl. Sysfs might even be more 
flexible and allowing for unexpected changes in the future.

Finally, even if a sysfs for DF existed, it's just a pseudo-filesystem 
so no one would be required to use it.

Isn't that basically what sysfs is?
