It won't contain all devices, just the bare minimum needed to open a console etc. The rest are created dynamically when udev starts, all you need before then is enough to get you to that point. > But it did not fix the issue. Then you have a different problem, since the dev directory of the root partition (which is not the same as /dev on the booted system) should now contain the same on both disks. -- Neil Bothwick Isn't it a bit unnerving that doctors call what they do "practice?"
