Previously we were trying to copy the root cg properties recursively to attempt to correct invalid restores. However, based on some ML discussion, we should only restore exactly what was dumped. Users need to set up their cg heirarchies correctly (that is, they should not set up any options in the parent that would conflict with what was dumped) in order to restore successfully.

criu ==== An utility to checkpoint/restore tasks. Using this tool, you can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at. The distinctive feature of the CRIU project is that it is mainly implemented in user space. The project home is at http://criu.org Pages worth starting with are * Kernel configuration, compilation, etc: http://criu.org/Installation * A simple example of usage: http://criu.org/Simple_loop * More sophisticated example with graphical app: http://criu.org/VNC
