title: Docker apache guacamole - GUACAMOLE_HOME wont change
body: <p>I use apache guacamole on docker-compose, and it seems that it is impossible to edit tomcat HTML files.
  I really need to delete the user &quot;home&quot; button from control panel (ctrl + alt+ shift)</p>
  <p>I have tried adding new extension but i cant because when i set
  <code>GUACAMOLE_HOME</code> to &quot;/guacamole-home&quot; where i created a .jar of new extension its always setting it to the default &quot;/root/.guacamole&quot;.</p>
  <p>How can I make this work? even if there's another way to edit the client.html in guacamole on another way</p>
