Opening a task on systemd as well for this.

When called early in boot, mount.nfs may fail because of any number of
problems with the network.  In this case, it appears it's being called
by systemd before /etc/resolv.conf has been set up, resulting in a
temporary DNS failure.  There is no way for mount.nfs to work when
invoked at this point in the boot.

So either systemd needs to more finely control the timing of the mount
call so that it definitely happens only after the network is up
(including /etc/resolv.conf configuration), or it needs to handle
retrying the mount in the case of a temporary failure.  (The latter is
what mountall did in Ubuntu 14.10 and earlier.)

Title:
  NFS shares in FSTAB no longer mount at boot

Status in nfs-utils package in Ubuntu:
  New
Status in systemd package in Ubuntu:
  New

Bug description:
  After a fresh install of 15.10, nfs shares no longer mount on boot.
  I'm using the same line to mount as I did in 14.04 prior:

  <server>:/share  /mnt/share  ntfs4  _netdev, auto 0 0

  This line worked just fine in 14.04, and 14.10 on my laptop, to mount
  the shares at boot.

  Manual mounting after boot works fine.  Systemctl shows a name
  resolution failure (see below)
