Checkpoint and Restore Applications with CRUI

The CRIU (Checkpoint/Restore in User-space) projects offers a user-space implementation of process and process group checkpoint/restore. With the user-space tools crtools included in this release it is possible checkpoint processes and restore them at a later time again (e.g. after a crash) or migrate the checkpointed process or process group to another system. CRIU aims to be as transparent as possible so that no instrumentation or re-compilation of the process to be checkpointed is necessary.

Using the `crtools` package, users can easily checkpoint and restore processes with the crtools package:

`crtools dump -D <dump-directory> -t <PID>`

`crtools restore -D <dump-directory -t <PID>`

To learn more about CRUI, visit http://criu.org and read `man 1 crtools`
