Not quite. It still does need the sentence:
"Please upgrade your kernel before or while upgrading udev."
Perhaps even better:
"Please upgrade your kernel before upgrading udev."
to precede it, since that would obviously be the best way to proceed. Get the
kernel on first - after all, there are such things as power cuts. You might
install udev, then have e.g. a power cut.
