FWIW, I'm *not* using NIS (as is the case in

Title:
  rpc.statd not started automatically

Status in nfs-utils package in Ubuntu:
  Confirmed

Bug description:
  Hello,

  I've noticed that if my NFS mounts do not have the 'auto' option,
  rpc.statd does not start automatically, without a password.

  When I try to mount the share, I'm prompted for the sudo password, in order to start rpc.statd.
  If the current user does not know the password, he cannot start rpc.statd and thus cannot mount the share.

  Here is a sample session:
  $ mount /media/xxx
  [a popup window opens to prompt for a password, choose "cancel"]
  Failed to start rpc-statd.service: Access denied
  See system logs and 'systemctl status rpc-statd.service' for details.
  mount.nfs: rpc.statd is not running but is required for remote locking.
  mount.nfs: Either use '-o nolock' to keep locks local, or start statd.
  mount.nfs: an incorrect mount option was specified

  /var/log/syslog contains:
  Sep 17 20:22:41 mcqueen rpc.statd[5160]: Opening /run/rpc.statd.pid failed: Permission denied

  $ systemctl status rpc-statd.service
  ● rpc-statd.service - NFS status monitor for NFSv2/3 locking.
     Loaded: loaded (/lib/systemd/system/rpc-statd.service; enabled; vendor preset
     Active: inactive (dead)

  /etc/fstab entry:
  192.168.0.5:/volume1/documents  /media/xxx       nfs     user,noauto    0       0

  Of course, if I enter the sudo password, or if I manually start
  rpc.statd as root before trying to mount, the mount operation
  succeeds.

  Similarly, if I replace "noauto" with "auto", rpc.statd is started
  during the boot sequence, and everything works.

  Yet, I'd expect that any user be able to mount this share, since it
  has the "user" option.

  Problem currently noticed with ubuntu 16.04.
