Comment 3 for bug 1590799

the workaround described earlier here does not seem to work.

starting with a clean install, a simple export, and no changes in /etc/default/nfs-*

the first error message in the journal was " rpc.nfsd: invalid option -- 'v' "

this worked:
> systemctl add-wants multi-user.target rpcbind.service
> systemctl restart nfs-kernel-server

then add the restart to /etc/rc.local and the system will reboot with nfs services running - otherwise it will not start, instead showing "Dependency failed for NFS server and services" in the journal
