nfs4 is know not to work with overlayfs, and I think you may be mixing your pxe configs. I'm using a stretch nfs root via nfs3.
I have an exports like this: /srv/fai/nfsroot *(async,ro,no_subtree_check,no_root_squash) /srv/fai/config *(async,ro,no_subtree_check,no_root_squash) ..and a pxe append line like this: append initrd=initrd.img ip=dhcp root=1.2.3.4:/srv/fai/nfsroot rootovl FAI_FLAGS=verbose,sshd,createvt,reboot FAI_ACTION=install It all works fine.
