This component exists solely to provide the correct dependency structure to the component framework so that, during shutdown, when all components that depend on devfs are removed, the driver manager can be signalled that driver shutdown can commence.
This component should automatically be included in most builds. To add this component to your build, append --with-base src/devices/bin/devfs to the fx set invocation.
Use ffx component run to launch this component into a restricted realm for development purposes:
$ ffx component run /core/ffx-laboratory:devfs fuchsia-pkg://fuchsia.com/devfs#meta/devfs.cm
