           Path to uevent helper program forked by the kernel for
           every uevent.
+          Before the switch to the netlink-based uevent source, this was
+          used to hook hotplug scripts into kernel device events. It
+          usually pointed to a shell script at /sbin/hotplug.
+          This should not be used today, because usual systems create
+          many events at bootup or device discovery in a very short time
+          frame. One forked process per event can create so many processes
+          that it creates a high system load, or on smaller systems
+          it is known to create out-of-memory situations during bootup.
