I have two diskless frontends, and both recover just fine after 
rebooting the server. My config:

LABEL linux
        kernel vmlinuz-2.6.30-2-686
        append rootfstype=nfs root=/dev/nfs 
initrd=initrd.img-2.6.30-2-686 nfsroot=192.168.1.2:/raid/netboot/bedroom 
ip=dhcp rw

I do NOT have the root filesystem listed in my /etc/fstab on the 
clients.  It doesn't seem to hurt anything not having it there.

On my system at least (Debian Squeeze), it uses TCP by default, as well 
as hard mounting.  Looking at /proc/mounts:

192.168.1.2:/raid/netboot/bedroom / nfs 
rw,relatime,vers=3,rsize=262144,wsize=262144,namlen=255,hard,nointr,nolock,proto=tcp,timeo=7,retrans=10,sec=sys,addr=192.168.1.2
