 +=== Fedora 33 ===
 +The upstream version of docker //​moby-engine//​ can be installed directly from Fedora repositories:​
 +<​code>​
 +dnf install -y moby-engine
 +</​code>​
 +
 +It's necessary to configure the //dockerd// daemon to run with cgroupdriver=cgroupfs,​ otherwise you encounter the following problem:
 +<​code>​
 +$ docker run hello-world
 +docker: Error response from daemon: OCI runtime create failed: cgroup v2 not enabled on this host, can't use systemd (rootless) as cgroups manager: unknown.
 +</​code>​
 +
 +To configure the cgroup driver one needs to override the //​ExecStart//​ for docker.service:​
 +<​code>​
 +$ systemctl edit docker
 +ExecStart=/​usr/​bin/​dockerd \
 +          --host=fd://​ \
 +          --exec-opt native.cgroupdriver=cgroupfs \
 +          $OPTIONS
 +</​code>​
