When running criu in swrk mode the client typically wants to know the reason of failure. Right now criu reports back NOTHING but the fact that dump/restore/etc fails. We've tried to address this by introducing the cr-errno engine, but it doesn't seem to be informative enough and is hard to maintain -- adding new errno-s is boring :( I propose to report back the first message with ERROR level upon failrure as __typically__ the very first error message indicates that proceeding is impossible and criu rolls back (generating more error messages, so it's crucial to know the very first one). If we ever meet the situation that the first pr_err/pr_perror doesn't cause criu to exit, this printing should be fixed to be pr_warn.

CRIU (Checkpoint and Restore in Userspace)
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
- A simple example of usage
- More sophisticated example with graphical app
A video tour on basic CRIU features
