 {op-system} is supported only as a component of {product-title} {product-version} for all {product-title} machines. {op-system} is the only supported operating system for {product-title} control plane, or master, machines. While {op-system} is the default operating system for all cluster machines, you can create compute machines, which are also known as worker machines, that use {op-system-base} as their operating system. There are two general ways {op-system} is deployed in {product-title} {product-version}:

When the last machine under the bootstrap machine's control is completed, and the services on those machines come up, the work of the bootstrap machine is over.
