CRIU, on the other hand, doesn't require any libraries to be pre-loaded on the application start. It will dump any application. But to do so, CRIU requires a certain information to be fetched from kernel, and if it can't be done, the respective patch is submitted to the kernel community. This means, that CRIU supports all the features only on the recent kernel. However, this is temporary situation. One day kernel API will be extended to the necessary level.
