You are correct that my understanding of init scripts is thin. I
have included the script in question below. You see that my script
uses the killproc subscript in /etc/init.d/function, which I am
guessing, sends the correct signals. I think the real problem is
that this process needs to be killed quickly, perhaps more so than
usual. The best solution I can see would be to add a system call to
my process with which it could ask whether the system is in the middle
of a shutdown. As yet, I have not found this.
Thanks for your help.
Mike.
