Hi All,

I think it's essential.
Without 'udevadm trigger --action=add', the system start-up process may 
have some problem. I can recall that once I removed this line from the 
init scripts in my live image, the image could not boot up correctly.

I think this patch is reasonable and I'd like to acknowledge it.
