title: Crontab @reboot command not attaching to a screen
body: <p>I run a minecraft server on a remotely hosted linux VPS. Recently, a migration was done at my host's data center where the VPS image was copied to a new setup (new hardware, new IP, new virtual infrastructure I believe). </p>
  
  <p>Before the migration, the server had the below command crontab'd and it worked fine; after a full reboot, I could type "screen -x" to get into the server console. After the migration, I cannot do this anymore. The command itself starts the minecraft server... but not the 'screen'. I have asked the host to explore why and he tested it out and replied he can't find the reason either.</p>
  
  <p>The main changes I know of at the time of migration...  upgrade from 13.x to 14.04 Ubuntu; update from Java 6 to Java 8...  update to newest MySQL...  storage upgraded to SSD. Changed from "Xen" to "KVM"... and new setup supported by OpenStack.</p>
  
  <p>@reboot cd /home/mcma &amp;&amp; screen -dmS minecraft /home/mcma/MCMA2_Linux_x86_64</p>
  
  <p>I wish I could provide more info but this is everything I have at hand, I don't know how to troubleshoot further. Any assistance would be greatly appreciated. </p>
