bundle common g
{

    "diediedie" or => { "linux" };
}

bundle agent suicide
{   
classes:
    "diediedie" or => { "linux" };
reports:
linux.diediedie::
    "I should be dead now";
}

bundle agent glados
{
reports:
    diediedie::
        "GLADoS status: still alive!";
}

If the agent is run with -D immunize, the "diediedie" class gets defined before the action starts so it doesn't die in the suicide bundle anymore.
