I would worry about programs which are using files which have been deleted, renamed, or (very common) renamed-over by another process after being opened, as there's a good chance they will successfully open the wrong file after c/r, and corrupt state from then on. This can be avoided by ensuring every checkpointed application is specially "c/r aware", but that makes the feature a lot less attractive, as well as uncomfortably unsafe to use on arbitrary processes. Ideally, c/r would fail on some types of process (e.g. using sockets), but at least fail in a safe way that does not lead to quiet data corruption. -- Jamie _______________________________________________ Containers mailing list [email protected] https://lists.linux-foundation.org/mailman/listinfo/containers _______________________________________________ Devel mailing list [email protected] https://openvz.org/mailman/listinfo/devel
