Unless you compile your kernel with: CONFIG_DEVTMPFS=y CONFIG_DEVTMPFS_MOUNT=y In which case the kernel mounts a tmpfs on /dev and populates it with device nodes before udev gets started. I don't create the console or null dev nodes (I deviate from the book) as the kernel creates them every time it boots.
