In the documentation for showing how to install a medium installation:
...it is said:
This first host holds all roles to help bootstrap the rest of the installation, but you will remove some of its roles in a later step.
Actually I am missing this later step on that page - if I am not mistaken.
So: Does someone please tell me (example line) how to remove a allocator role from the firs node using either the install script or the API.
