title: jenkins with slave nodes /tmp disk space too low
body: <p>I added a slave node to jenkins master server system. It tells me the /tmp directory size for that slave node is too low. Is there a possibility to increase the disk space for /tmp? </p>
  
  <p>I get the error:</p>
  
  <pre><code>Disk space is too low. Only 0.511GB left on /tmp.
  </code></pre>
