_criu_ rebased to version 2.3
Red Hat Enterprise Linux 7.2 introduced the *criu* tool as a Technology Preview. This tool implements *Checkpoint/Restore in User-space (CRIU)*, which can be used to freeze a running application and store it as a collection of files. Later, the application can be restored from its frozen state.
Note that the *criu* tool depends on *Protocol Buffers*, a language-neutral, platform-neutral extensible mechanism for serializing structured data. The _protobuf_ and _protobuf-c_ packages, which provide this dependency, were also introduced in Red Hat Enterprise Linux 7.2 as a Technology Preview.
With Red Hat Enterprise Linux 7.3, the _criu_ packages have been upgraded to upstream version 2.3, which provides a number of bug fixes and enhancements over the previous version. Notably, *criu* is now available also on Red Hat Enterprise Linux for POWER, little endian.
Additionally, *criu* can now be used for following applications running in a Red Hat Enterprise Linux 7 *runc* container:
* apache httpd
