I put a date timestamp at the beginning and end of the start command of
init.d/udev, and when you stop and then start init.d/udev it shows a ~5s
delay. At boot I don't see this delay, but instead see the initial date
stamp, then a flurry of parallel activity, then the final date stamp, which
shows the ~5s delay.


Thanks!
