Public bug reported:
Impact: NFS shares listed in /etc/fstab do not mount on boot.
During booting, it appears that the nfs share attempts to mount before
the network allows for name resolution (see errors below). However, the
systemd dependencies clearly show a requirement for network-
online.target (see below). After booting, shares can be mounted fine via
mount -a.
Regression potential: This same issue appears to have been addressed in
LP: #1515446 but I observe the problem on a fresh install of kubuntu
16.10.
Configuration and error logs:

options fixes this.
