I understand that udev needs or used to need uevent_helper, but I am not clear 
if I should or should not enable this module in a new kernel I'm rolling.  Can 
you please advise:


CONFIG_UEVENT_HELPER:

The uevent helper program is 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.

Symbol: UEVENT_HELPER [=y]
Type  : boolean
Prompt: Support for uevent helper

Support for uevent helper (UEVENT_HELPER) [Y/n/?] (NEW)
