title: Create an apt-cache on host for multiple vagrant installations
body: <p>When you startup a vagrant box using a bootstrap.sh, you have to download all packages with apt-get inside each box again.</p>
  
  <p>How can I set up an external folder on my host, that is used for all boxes as cache?</p>
  
  <p>Maybe somehow adding the apt-cache folder in the <code>Vagrantfile</code> lilke this?</p>
  
  <pre><code>config.vm.synced_folder "/var/cache/apt/archives/", "/var/cache/apt/archives/"
  </code></pre>
