Title:
  Shutdown hangs with systemd and NFS mount

Status in systemd package in Ubuntu:
  New

Bug description:
  I have the following line in /etc/fstab:
  192.168.1.5:/srv/nsf4/main      /shares nfs     noauto,nofail,x-systemd.automount,_netdev,x-systemd.device-timeout=14,size=32768,wsize=32768 0 0

  This works properly in the sense that systemd does not hold up the
  system when booting, and it does mount the directory upon first
  access, however the system hangs at shutdown in a manner consistent
  with systemd shutting down the network before attempting to unmount
  the drive. Indeed, even when the system is running, I can manually run

  systemctl stop NetworkManager.service

  and/or

  systemctl stop network.target

  and a call to

  systemctl status shares.mount

  shows that the mount is still active.

  Finally, I will describe the debugging I have done to this point.
  First, if I manually unmount the share before shutting down, it shuts
  down immediately. Second, it should be noted that this does not in
  anyway depend on using the x-systemd.automount option. The same thing
  happens without automount (or fstab for that matter - simply manually
  mounting an NFS share and shutting down results in the computer
  getting stuck on the shutdown screen). I also tried adding additional
  items to the Require= and After= lines for shares.mount, specifically
  I tried adding network.target, NetworkManager.service, and
  wpa_supplicant.service. In each case, I did observe that manually
  running

  systemctl stop NetworkManager.service

  (for instance) now did cause the share to be unmounted, however if I
  shutdown the computer without manually stopping these services it
  would still stall on the shutdown screen. I can leave it for over 10
  minutes, at which point I manually power it off.
