FAI never used these options:
  rd.live.overlay.overlayfs=1 rd.live.overlay.readonly=1
I'm pretty sure they will break things.
Instead you have to use the option rootovl.

There may be problems if your nfsroot is not build properly. First,
which FAI version are you using? Do you use systemd inside the nfsroot?
FAI 6.2 uses systemd during the installation and if you still have an
older /etc/fai/NFSROOT config file systsemd may be missing inside the
nfsroot. If you still have this line in NFSROOT (when using FAI 6.2),
please remove it abd rebuild your nfsroot.

If you are using FAI < 6.2, the nfsroot does not use systemd and I
wonder why you have added some systemd.log... options to the kernel
command line.
