fai 5.3 + debian stretch NFS issues

[Justin Cattle]

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.





Cheers,
Just
