FWIW, this is how I've been working, and it hasn't been /that/ difficult to get working. The Tegra side is trivial, just append something like ip=dhcp root=/dev/nfs nfsroot=host_ip:/your/nfsroot,v3,rsize=8192,wsize=8192,timeo=15 (Granted, I had to do a bit of mucking around before finding this working incantation..) to the kernel boot arguments. I've used Ubuntu 12.04, 13.10 and Arch Linux on my Jetson in this way. The more annoying part is the nfs host machine, but there are guides for that. Anyway, I've had both Ubuntu 12.04 and Arch working as hosts without problems.
