Hi Mike,
I installed the x2gothinclientmanagementscripts on the Ubuntu 14.04.
Then I setup everything within the chroot to be the standard Debian /Wheezy
When i tried to boot the image via Pxe/tftp, it did not work.
So i am sure there is an issue somewhere that prevents the thinclient envinroment to fail on the new 14.04 trusty.
However I believe that docker again can help us do things more easily than this cumbersome /larger setup. I will try and create a thinclient envinroment that directly boots via docker and is much easier to setup this weekend.
