title: Magento layout update XML change impacting all pages
body: <p>I'm trying to add a static block (which is actually a text link) after my site's home page only, by using the Layout update XML box on the CMS pages interface.</p>
  
  <pre><code>--------------
  |             |
  |   Content   |
  |             |
  ---------------
  |  Footer     |
  |  Copyright |
  ---------------
  | My Block    |
  ---------------
  </code></pre>
  
  <p>I've tried adding the block using this code:</p>
  
  <pre><code>&lt;reference name="footer"&gt;
      &lt;block type="cms/block" name="credits" after="-"&gt;
          &lt;action method="setBlockId"&gt;&lt;block_id&gt;my_block&lt;/block_id&gt;&lt;/action&gt;
      &lt;/block&gt;
  &lt;/reference&gt;
  </code></pre>
  
  <p>The problem is: #1 that my block shows between the Footer and Copyright and #2: the change is visible on all the pages, whereas I only want it to show on my home page and not in the rest of the site...</p>
  
  <p>Note: I'm running a Magento 1.4.0.1</p>
