This commit is in preparation for the (hopefully last :) restore special cpuset patch. Previously, we installed the cgroup service fd after calling prepare_cgroup_dirs, which meant that we had to carry around the temporary directory name in order to put things in the right place. The restore_cgroup_prop function uses the cg service fd instead of carrying around the full path. This means that we can't sue restore_cgroup_prop, without first sanitizing the path. Instead, we install the service fd before calling prepare_cgroup_dirs, and all the code just references that instead of carrying around the temporary path.

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
