there is a new, succinct systemd auto-mount option which can be used with fstab which allows you to use all the standardized mount permission options, and it looks like this:

<code>
  x-systemd.automount
</code>
an example of it in an fstab line:

<code>
  /dev/sdd1   /mnt/hitachi-one     auto     noauto,x-systemd.automount     0 2
</code>

the noauto option will mean it will not attempt to be mounted at boot, as with older software autofs.

after adding a new x-systemd.automount line to fstab you then need to run:

<code>
  sudo systemctl daemon-reload
</code>
and then both, or one, of the following:

<code>
  sudo systemctl restart remote-fs.target
  sudo systemctl restart local-fs.target
</code>
