[wlug] nfsroot

Hi, I have managed to get my iMac to netboot the Linux kernel. The kernel seems to load fine, but stops with a kernel panic as it can't mount the root filesystem. I'm using the default 2.4 kernel from Debian 3.0. As per the instructions for yaboot (the Open Firmware boot loader that LinuxPPC uses), i set "root=/dev/nfs". Is this what i'm supposed to do to get / mounted via NFS? Is this a sign the kernel doesn't have nfsroot support? I found a web page that suggested i add "fsroot=$SERVER:/export/root", but that didn't help. Does anyone have any ideas? Thanks, Jon
