Comment 1 for bug 288327

This is a side-effect of how Ubuntu-mid handles X, and how casper handles a reboot event, with a prompt to remove the boot media (which is then obscured by the restarting X from the upstart job). One way to address this would be to have casper detect ubuntu-mid, and not prompt for removal on shutdown. Another would be for ubiquity to specifically stop the upstart session job when preparing to reboot. A third would be to replace this means of starting X with something else.
