(copyied from the NFS-Root Howto)
If the workstation will be booted without kernel parameters, you need
also to set the root device to 0:255. Do this by creating a dummy
device file with
  mknod /dev/nfsroot b 0 255
After having created such a device file, you can set root device of the
kernel image with
  rdev <kernel-image> /dev/nfsroot.
