        docker exec -t -i 1302a1dbd5ff09e720c566ea6b87f1233f0cc14370022a900bdc84e8d07a27f5 /bin/bash

As an alternative you can get a pre-built container:

```docker pull maci0/systemd```

Or just run it using the default docker command (this should pull the image automatically):

```docker run -v /sys/fs/cgroup:/sys/fs/cgroup:ro maci0/systemd```
