Well, do you really want your kernel to be creating 2 userspace programs for every device in sysfs that is created? Remember, we can't just not emit that hotplug event, too many programs need it.... > Also, since most people never need to do anything except modprobe, they > can still have a working system without any scripts what so ever... again > just like normal on demand module loading. Lots of programs do lots of stuff other than modprobe on hotplug events. Look at HAL for just one example. thanks, greg k-h ------------------------------------------------------- This SF.Net email is sponsored by Oracle Space Sweepstakes Want to be the first software developer in space?
