 #### Application Bundle Builders
 
 Application bundle builders can create a [bundle](bundle.md) directory that includes all of the files required for launching an application as a container.
-The bundle contains OCI [configuration files](config.md) where the builder can specify host-independent details such as [which executable to launch](config.md#process-configuration) and host-specific settings such as [mount](runtime-config.md#mount-configuration) locations, [hook](runtime-config.md#hooks) paths, Linux [namespaces](runtime-config-linux.md#namespaces) and [cgroups](runtime-config-linux.md#control-groups).

 Because the configuration includes host-specific settings, application bundle directories copied between two hosts may require configuration adjustments.
 
 #### Hook Developers

-### Review the need for runtime.json (Target release: v0.3.0)

-There are some discussions about having `runtime.json` being optional for containers and specifying defaults.
-Runtimes would use this standard set of defaults for containers and `runtime.json` would provide overrides for fine tuning of these extra host or platform specific settings.

 ### Define Container Lifecycle
 
 Containers have a lifecycle and being able to identify and document the lifecycle of a container is very helpful for implementations of the spec.

 The definition of a bundle is only concerned with how a container, and its configuration data, are stored on a local file system so that it can be consumed by a compliant runtime.
