For example, the `command` and `args` parameters in the `containers` section of the DaemonSet may look something like:
```
command: ["/entrypoint.sh"]
command: ["/thin_entrypoint"]
args:
- "--multus-conf-file=auto"
- "--namespace-isolation=true"

The automatic configuration option is used to automatically generate Multus configurations given existing on-disk CNI configurations for your default network.
In the case that `--multus-conf-file=auto` -- The entrypoint script will look at the `--multus-autoconfig-dir` (by default, the same as the `--cni-conf-dir`). Multus will wait (600 seconds) until there's a CNI configuration file there, and it will take the alphabetically first configuration there, and it will wrap that configuration into a Multus configuration.

--cleanup-config-on-exit=true
When specifying `--cleanup-config-on-exit=true` the entrypoint script will delete any generated/copied Multus configuration files when entrypoint script
exits (upon Pod termination). This allows Multus to be safely removed from the cluster when its no longer needed.
In addition, when both `--cleanup-config-on-exit=true` and `--multus-conf-file=auto` are specified, the entrypoint script will watch for changes of the
master CNI configuration and kubeconfig. when such change detected, the script will re-genereate Multus configuration. Watch can be skipped by setting:
--skip-config-watch
Additionally when using CRIO, you may wish to have the CNI config file that's used as the source for `--multus-conf-file=auto` renamed. This boolean option when set to true automatically renames the file with a `.old` suffix to the original filename.
