    defaults are used by this backend.

<dl>
  <dt>Description</dt>

  <dd>`/sys/mounts/<mount point>`</dd>

  <dt>Parameters</dt>
  <dd>
    <ul>
      <li>
        <span class="param">type</span>
        <span class="param-flags">required</span>

        <span class="param">description</span>
        <span class="param-flags">optional</span>

      <li>
        <span class="param">config</span>
        <span class="param-flags">optional</span>
        Config options for this mount. This is an object with
        two possible values: `default_lease_ttl` and
        `max_lease_ttl`. These control the default and
        maximum lease time-to-live, respectively. If set
        on a specific mount, this overrides the global
        defaults.
