              I have opened a Change
                Request to change the defaults for Fedora 31 to

                Cgroups V2.  I am looking for what packages will be
                affected by this

                change.   Basically any package that adjusts Cgroups via
                the CgroupFS,

                my understanding is working the the systemd APIs, you
                should be fine.

                
                Packages That I know will be affected:

                
                Container Tools

                
                * Runc, Podman, Buildah, Kubernetes, Docker, Moby-engine

                
                Virtualization tools

                
                * Libvirt

                
                Java

                
                * jvm

                
                Install

                
                * Anaconda

                
                Anyone know of other packages?

              
              Great news!

              
              Can you briefly summarize the status / plans / timelines
              for the

              affected components?

              (Apart from anaconda, which doesn't need changes, we'll
              just flip the

              default in systemd, as discussed in the other subthread.)

              
            snapd will break in cgroupv2 mode:

            https://bugzilla.redhat.com/show_bug.cgi?id=1438079

            
            I don't know of anyone working on
              fixing that…
        
        
        I think the stance of the snapd team is that once v2
          supports freezer we can have a look at adding the support.
        

    Freezer is supposed to go into Kernel 5.1, I have been told.

    
        There’s a snapd bug tracking this as well: https://bugs.launchpad.net/snapd/+bug/1801664
        

        I’m happy to work on this issue once it becomes „pressing”
          and once the prerequisites are available. If F30 disables v1
          entirely and has a kernel where we can get device, freezer and
          pid controllers then it’s „just” a matter of coding.
        

    Device Cgroup is supposed to be done in eBPF, and systemd has an
      implementation I believe.
    This is for F31 NOT f30.  Also you will be able to boot the
      machine in V1 mode. We are just talking about the default here.

    
        Best regards
