Sorry about the confusion, I meant SIGTERM instead of SYSTERM.
Create a file with a known fixed name when the daemon starts, and remove  
it after a clean shutdown (you may want to write the daemon's PID). If the  
file already exists the next time it starts, that means that a clean  
shutdown was not performed.
(Note that this, and the previous question, are not specific to Python)
