I have not tried this configuration (rootfs over NFS) yet, will give
it a try soon. Also please note that the default qlogic NIC on Sabre
may not work with FreeBSD.
I had setup the FreeBSD partition on my system by creating a freebsd
disk image in kvm/qemu and then copying the image to a partition -
this works well.
