Docker ce with Criu

Hi folks,

we work in a HPC environment where we want to checkpoint long running processes every couple of days.
So far checkpointing and restore seems to work fine with latest docker-ce and criu 2.3.
But we also occasionally do system updates and while restore was okay after a kernel update I wasn’t able to restore after upgrading from CentOS7.2 to CentOS7.3 (error about cgroup mount failed)

So the question is? What are the goals/roadmap about criu integration into docker? Is there, after all, a lesser chance of breakage using docker instead of non-containerized criu apps?

thanks & greets
