[Pm-utils] stopping custom services

[Kibanadai]

Hello guys,
I have some questions and associated concepts which I would request you to 
explain/answere.
(1) Let me start with a question.

I am using suse 10.2 with pmutils. What I would like to do is following. I 
would like to be able to define some services in /etc/pm/config which will be 
stopped before suspending the computer and restarted after resuming (as one 
can define modules). How do I do this?

(2) Here is what I understand. One can define custom hook which would utilize 
startservice and restartservice functions defined in /etc/pm/function. 
However, I want to be able to define a global configuration variable (like 	
SUSPEND_MODULES) say SUSPEND_SERVICES. At present, I see that the easiest way 
to do is add this variable in /etc/pm/functions and also in /etc/pm/config. 
Is this is the only way?

(3) From documentation, I understand (not fully though) that config.d 
directory is provided so that one can put their custom configuration file 
there. How do I use this functionality if I don't want to touch the 
default /etc/pm/config file at all to define my custom variables? Could some 
one elaborate a bit what exactly source_config function in /etc/pm/function 
does to the files present in config.d directory?
