Hi Marcel and other responders, Thanks for the response, even the shameless plug. I plan to look into those projects for my company.
Yes, I do have a management agent. Unfortunately, it is not in its own bundle, but is instead included in the bundle that is often found stopped. I now believe that might be what I have to change (separate it out). I'll do that. Hopefully the separated bundle will rarely need to change.

If this bundle already has knowledge about what to update and when, then it is probably also the best place to make sure everything stays "active". > On a related note, especially if there is no solution to the above, > has anybody figured out a good way to issue framework commands from > outside the framework?

We also have a web console that you can use to remotely "manage" the framework. There also is a JMX based interface to (again remotely) connect and manage bundles. ...and I might be forgetting one or two... ;) > So, problem 1) start Felix and force all installed bundles to start, > no matter where they left off.
