title: WSLv2 mount option missing from wsl util
body: <p>I'm using wslv2 on Windows 10 Pro running on the dev channel. I've made sure it's fully up to date, then completely uninstalled wsl and ubuntu, then reinstalled them.</p>
  <p>Despite this, I don't have a working mount option :(</p>
  <pre><code>wings@machine:~$ wsl --mount
  Unknown command: --mount
  </code></pre>
