Indeed, the kernel client is intended to get an IP address,netmask and 
default route early enough in the boot process to do 
root-filesystem-over-NFS. It is necessary to run a normal user-space 
DHCP daemon once the machine is up. I've not tried all the clients, but 
dhcpcd at least will smoothly take-over the existing kernel-aquired 
lease in this situation.
