   Fundamentally, they are the same.   The OS is simply a more complicated   
   program and thus more difficult to analyze post-crash (and requires   
   skill-sets that include multithreaded programming, multiprocessor   
   synchronization and low-level hardware familiarity).   
      
   Both typically use the ELF container to store the state and memory contents   
   at the time the program/system crashed.
