NixOS now defaults to the unified cgroup hierarchy (cgroupsv2).
See the <link xlink:href="https://www.redhat.com/sysadmin/fedora-31-control-group-v2">Fedora Article for 31</link>
for details on why this is desirable, and how it impacts containers.
</para>
<para>
If you want to run containers with a runtime that does not yet support cgroupsv2,
you can switch back to the old behaviour by setting
<xref linkend="opt-systemd.enableUnifiedCgroupHierarchy"/> = <literal>false</literal>;
and rebooting.
