Sparc Netbooting

Hi,

I have a main server system, Sparcserver 20 running debian testing, 
which I want to be the boot server for some other sparc boxen on the 
network. I have set up RARP and TFTP so that the nodes can collect a 
kernel and boot it but the problem comes when it tries to load the root 
filesystem. I want it to load it's root filesystem over NFS from the 
Sparcserver.

When I was compiling the kernel I could not find the "enable root fs 
over nfs" option anywhere, either in menuconfig or Xconfig. In the end 
I manually found the option in .config and enabled it. This caused the 
compiling of the kernel to die with the following error:-.

Does this mean that It is not possible to enable root fs over nfs on 
the sparc platform or am I missing something simple.

Thanks in advance
