It sounds like you've got a better working NFS setup than I managed to
get working...

In /usr/share/doc/ltsp-server/NEWS.Debian:

  LTSP defaults to using NBD in both ltsp-build-client and in
  ltsp-client-core, due to incompatibilities using overlay fs from linux
  4.x with NFS as a backend.


Another person reported similar issues:

  https://sourceforge.net/p/ltsp/mailman/message/36038589/
  https://bugs.debian.org/875821

It may be possible to switch to aufs by using the aufs-dkms package, as
aufs is what was used before stretch.

Another option would be fixing the way LTSP mounts using "overlay" fs,
as NFS + overlay fs is used by FAI apparently without issue. FAI uses
dracut instead of initramfs-tools, so that could be a path of further
investigation.
