This implementation of Component Manager allows command line tools to connect to services exposed by session_manager at runtime.
TODO(45361): Remove this work-around implementation entirely.
See below for details.
Since this binary is exclusively run in the context of using session_manager, refer to the instructions there.
The entrypoint is in src/main.rs.
It is currently impossible for a command line tool to acquire a service directly from a v2 component. This workaround uses a custom implementation of Component Manager to bridge service brokerage between the world of v1 components and v2 components.
This implementation exposes services from its child's exec/expose/svc outgoing directory in its out/svc directory.
Used in combination with sysmgr‘s knowledge of components’ out/svc directories, this component can be used to allow command line tools to ask for specific services and have them provided by an instance of session_manager.
For example, it provides session_manager.config to sysmgr and allows session_control to connect to the fuchsia.session.Launcher service through session_control's environment.
