doesn't work.

The kernel never leaves the "DHCP/BOOTP timeout for server"-loop unless I hand out a root-path option via DHCP.

I tried your tip above, I tried setting ROOTDEVNAME in the kernel, I created a /boot.config with "-r" in it on the NFS root - all to no avail.

Doesn't seem to work either.
