title: Why is root directory always stored in inode two?
body: <p>I'm learning about Linux filesystems, with these sources:</p>
  <pre><code>http://linuxgazette.net/issue21/ext2.html
  http://homepage.smc.edu/morgan_david/cs40/analyze-ext2.htm 
  </code></pre>
  <p>But I have one question about the root directory: why is its inode number always <strong>two</strong>? Why not one, or another number?</p>
