Difference between become and become_user in Ansible : <p>Recently I started digging into Ansible and writing my own playbooks. However, I have a troubles with understanding difference between <code>become</code> and <code>become_user</code>. 
As I understand it <code>become_user</code> is something similar to <code>su &lt;username&gt;</code>, and <code>become</code> means something like <code>sudo su</code> or "perform all commands as a sudo user". But sometimes these two directives are mixed. </p>

<p>Could you explain the correct meaning of them?</p>
