Description of problem:
runc is supposed to support cgroup v2 now in F34+, but it seems that it is not working.
Upstream indicates that this is fully supported with rc93: https://github.com/opencontainers/runc/releases/tag/v1.0.0-rc93
Please update to a commit at or above this to fix it.
Version-Release number of selected component (if applicable):
1.0.0-364.dev.gite7bd1fb
How reproducible:
Always
Steps to Reproduce:
1. Install moby-engine
2. sudo docker run --rm -it registry.fedoraproject.org/fedora:34 /bin/bash
Actual results:
Error response from daemon: OCI runtime create failed: this version of runc doesn't work on cgroups v2: unknown"
Expected results:
Moby just works.
Additional info:
This is needed for Fedora CoreOS to finish transitioning to cgroup v2 as well: https://github.com/coreos/fedora-coreos-tracker/issues/292
