Then the question is, during the case when the machine needs to be
halted/powered off which unmounting must be done by root, how do you
overcome it? Or do we miss something from your question?

I'm sorry if my question was unclear. Let me reformulate:
How do I intercept and stop system calls like mount/read/write without modifying the system_call_table?
