Bruce is correct; This issue is not specific to udev/eudev/mdev. I suppose that what I am about to say isn't really relevant, but it is unfortunate over the past year that people blamed udev specifically for this. It is true that it does things that don't work if /usr isn't mounted, but eudev does as well, since it is basically the same code. If you read flameeyes' blog post, you will get a better idea of what the issue involves. It is the entire boot process and how to deal with which software is considered critical for booting. There is no reason to rebuild your server; we aren't telling you you have to merge /usr into /. The only thing we are saying is that you will need to use an initramfs if you are going to keep them separate. I have a pretty simple setup, but I have been using an initramfs which I built some time ago with genkernel and I barely know it is there. I recommend that you familiarize yourself with genkernel or dracut and build an initramfs. Since nothing is changing until at least Nov 1, you can test your initramfs by adding an entry to your boot loader configuration that uses it and get it set up correctly while you can still fall back on booting without it. I do not recommend that anyone who has separate /usr "do nothing" at this point. Please re-read the second paragraph of the news item.
