    I am a student studying computer security. I am trying to understand basic LSM architecture and would be grateful for clarification about these points or 
    pointers to relevant documents. Thanks.
    
    1. What security configuration does the base kernel have under LSM?. Is it nothing or is it the traditional root and others?.
    
    2. The LKM mechanism has a dummy LKM representing the statically-linked base kernel. Is LSM's initial module intended to be the first loaded module after 
    this dummy LKM.? 
    
    3. What does LSM's initial LKM  achieve? 
    
    4. How are system-calls affected?. How many additional system calls are implemented in the base kernel for LSM support? Do LSM modules implement more 
    system-calls?
    
    thank you
