# RUNTIME EXECUTION OPTIONS
You can configure the runtime using options specified with the `--exec-opt` flag.
All the flag's options have the `native` prefix. A single `native.cgroupdriver`
option is available.
The `native.cgroupdriver` option specifies the management of the container's
cgroups. You can only specify `cgroupfs` or `systemd`. If you specify
`systemd` and it is not available, the system errors out. If you omit the
`native.cgroupdriver` option,` cgroupfs` is used.
This example sets the `cgroupdriver` to `systemd`:
```bash
$ sudo dockerd --exec-opt native.cgroupdriver=systemd
```
Setting this option applies to all containers the daemon launches.
