[subsystems] how to list bundles installed with a subsystem ?

[Seth Lana]

Hi Aries users,

I'm playing with a composite Subsystem.
My esa file has two bundles embedded. its manifest contains every import 
package and import service needed by them.

I was able to install and start the subsystem properly. So, I infer that 
the embedded bundles are also installed at least, right?

But how to have a sure ?

Strangely, the Equinox "ss/status/s" command doesn't show even the 
dynamic bundle created for my subsystem.

23    ACTIVE org.eclipse.equinox.event_1.4.0.v20170105-1446
24    ACTIVE org.osgi.service.subsystem.region.context.0_1.0.0

But the felix:lb -s  shows it:

   23|Active     | 4|org.eclipse.equinox.event 
(1.4.0.v20170105-1446)|1.4.0.v20170105-1446
   24|Active     | 1|org.osgi.service.subsystem.region.context.0 
(1.0.0)|1.0.0
   25|Active     | 1|org.osgi.service.subsystem.region.context.1 
(1.0.0)|1.0.0

But any of those commands is showing the embedded bundles!

is there any command that can be used to list the bundles installed with 
a scoped subsystem ?

thanks,

Seth
