    >     append initrd=initrd.img-3.2.0-4-amd64 ip=dhcp root=nfs:/srv/fai/wheezy-amd64 aufs FAI_FLAGS=verbose,createvt FAI_CONFIG_SRC=nfs://leviticus/srv/fai/config FAI_ACTION=install FAI_SERIAL=0 HOSTNAME=kerberos-mit

This is my line:
append  initrd=initrd.img-3.2.0-4-amd64 rw aufs ip=dhcp root=/dev/nfs nfsroot=/srv/fai/nfsroot rd.shell FAI_FLAGS=verbose,sshd,createvt FAI_CONFIG_SRC=nfs://installserver/srv/fai/cskoeln FAI_ACTION=install rd.md=0 rd.dm=0 rd.lvm=0 rd.luks=0

Please check if NFS v3 is used and not NFSv4.
You can also add: rd.debug=1
for debugging.
