Use this image as a test case for securing Docker image hosts.

First, you can directly run:

```

/usr/bin/rootshell -p

```

This is just a copy of bash, which apparently requires an undocumented `-p` option:

Or, the root password has been removed and you can use the traditional `su`:

```

su - root

```
