A computing environment includes multiple client devices that may each be configured to serve a particular function within the computing environment. The client devices are each coupled to a client management server that communicates with and manages functions of the client devices. When a client device first boots, the client management server communicates with the client device over a network in order to provision the client device with an enrollment image. Using the enrollment image, a client device can become enrolled with the client management server. Once enrolled, the client management server can provision the client device with a functional operating system image. The functional operating system image can support device applications that require a restricted number of runtime states within the client device. A new functional operating system image is downloaded from the client management server and installed on the client device each time the device is rebooted.
