title: Linux (Ubuntu) Prevent User from Renaming Mounted Directory
body: <p>So, I have a FTP setup on Ubuntu. </p>
  
  <p>They have access to these directories as home:</p>
  
  <ul>
  <li>/home/{user}</li>
  <li>/home/{user}</li>
  </ul>
  
  <p>I have directories outside of home:</p>
  
  <ul>
  <li>/var/ftp/shared/legal</li>
  <li>/var/ftp/shared/finance</li>
  </ul>
  
  <p>The above are mounted to the users home directory as:</p>
  
  <ul>
  <li>/home/{user}/legal</li>
  <li>/home/{user}/finance</li>
  </ul>
  
  <p>My question is, how can I prevent the user from renaming their "legal | finance" directory in their home directory while being able to add directories and files? Would they even be able to do this by default?</p>
  
  <p>Thanks in advance</p>
