Is anyone else having issues with debian stretch?<br>
<br>
Our previous jessie configuration works fine, but after updating the nfsroot to wheezy we either get "mount.nfs: Protocol not supported" in dracut (with NFS 4) or overlay FS issues if we use NFS 3.<br>
<br>
FAI configs are default values other than file locations.<br>
<br>
I can mount using NFS V4 from the dracut shell but not using NFS V3 - our server supports both and I can mount either version from other machines so it's not the server side.<br>
