Yes, change the proc file (proc/sys/kernel/hotplug) to point to something else. > is there a way to see what does uevent_helper is set to in runtime ? 'cat /proc/sys/kernel/hotplug' For most modern distros, it is set to nothing because they are using udevd like I mention above. hope this helps,
yes, it does, as always :) Thank You naziir PS is there up-to-date documentation about udev ?
