title: How to override the systemd default LogLevel
body: <p>When I look at the file <code>/etc/systemd/system.conf</code> I can see the following:</p>
  
  <pre class="lang-none prettyprint-override"><code>[Manager]
  #LogLevel=info
  #LogTarget=journal-or-kmsg
  #LogColor=yes
  #LogLocation=no
  </code></pre>
  
  <p>But if I run <code>systemctl show -pLogLevel</code> the result is</p>
  
  <pre class="lang-none prettyprint-override"><code>LogLevel=notice
  </code></pre>
  
  <p>I tried to create a directory named <code>/etc/systemd/system.conf.d</code> and to add a <code>my.conf</code> file inside and then rebooted, but couldn't see any change.</p>
  
  <p>Am I looking at the right config file? </p>
