title: How to write systemd environment variables value which contains =
body: <p>In systemd units file, I have a Environment which content is <code>key=IamValue=abc</code>, as you can see the value is <code>IamValue=abc</code> which contains <code>=</code>.</p>
  
  <p>For this situation, how can I write the unit files?</p>
  
  <p>I have tried as following, but it seems invalid:</p>
  
  <pre><code>[Unit]
  Description=...
  
  [Service]
  WorkingDirectory=...
  ExecStart=...
  Restart=always
  RestartSec=10                                          
  SyslogIdentifier=...
  User=root
  Environment=key="IamValue=abc"
  </code></pre>
