NACK.

I'm probably missing the point here (as I was a bit suspicious about
waiting for devices in the first place), but I don't think this makes
sense.

Two cases where a missing udev means you won't get more devices:

1) If you reference them by symlinks in /dev/disks/by-*

2) If the required module is not built in to the kernel and udev is
needed for modprobing it.

However, you might very well have built your usb-drivers into the
kernel, referenced them as /dev/sdc1 (or whatever) and need to wait
for them to appear. Remember that udev no longer populates /dev with
devicenodes as this is done by the kernel.

Am I missing something?
