</span>> 1. It says "Clone CRIU repository from git://<a href="http://github.com/xemul/criu" target="_blank">github.com/xemul/criu</a> <<a href="http://github.com/xemul/criu" target="_blank">http://github.com/xemul/criu</a>>, checkout the 'p.haul' branch and compile it with 'make' ". However, there is no p.haul branch under criu.<br>
