Can you be more specific? > Do you mean: can we add the cpr specific bits to the migrate exec code? Yes; if possible I'd prefer to just keep the one exec mechanism. It has an advantage of letting you specify the new command line; that avoids the problems I'd pointed out with needing to change the command line if a hotplug had happened. It also means we only need one chunk of exec code. Dave > - Steve > -- Dr. David Alan Gilbert / dgilbert@redhat.com / Manchester, UK
