title: ssh-add error: "Permissions are too open"
body: <p>When trying to load my keys I get this error</p>
  
  <pre><code>ssh-add ~/.ssh
  Permissions 0755 for '/home/starkers/.ssh' are too open.
  </code></pre>
  
  <p>Note that the permissions are too open for the <code>.ssh</code> directory, not an actual key.</p>
  
  <p>Modifying the ownership doesn't change anything:</p>
  
  <pre><code>chmod 755 ~/.ssh
  ssh-add ~/.ssh
  Permissions 0755 for '/home/starkers/.ssh' are too open.
  </code></pre>
  
  <p>The thing is, I need to write to this directory when I create new keys, so what's it on about?</p>
