rootless containers can use pause on cgroups v2. Whether it is possible or not to use pause depends from multiple conditions, such as: - be on a cgroup v2 unified hierarchy, - using systemd cgroup manager, - the kernel has the freezer controller, The last one may fail for root as well. Instead of trying to catch all the possible conditions in Podman, let the OCI runtime complain if pause cannot be performed.
