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?
The Wiki has some notes on netbooting, under a variety of nodes. http://www.wlug.org.nz/NFSRoot is probably a good one to start at. A quick check of the config file for Debian 3.0's 2.4 kernel (2.4.18-bf2.4) shows that it doesn't have CONFIG_ROOT_NFS set, so I guess that's the current problem. As the page also says, your kernel options as above are right, but it might pay to set ip=dhcp as well.
