Ah. You're probably right. I assumed the boot loader would replace it. I never tested that though. My mistake. > >With udev I just created /dev/console and some others.

So you're right. But it's a thing to do in a generic initrd, not in an LVM-only one. There are a lot of other things you should probably think of in a generic initrd.
