I'd just like to say this is a very good question, and one I've often 
pondered myself.

Every newer version (Redhat 5.x up to FC2), seems to have more and more 
services turned on by default. And, like a lot of other people I'm sure 
we'd like to turn off the ones we don't use (I mean, if CPU speed is 
meant for laptops, why is it running on my desktop?). I also have not 
turned off a lot of them because I haven't a clue what they do, and I 
don't want to break the system.

Does anyone know of a list which specifically lists all services, what 
they do, and typical people that would/wouldn't need them?

If such a thing does not exist, instead of these few posting (which are 
not complete ofcourse) on a mailing list, maybe we should create a 
"services reference sheet"?

I bumped up against the same thing on Microsoft (40 non direct 
application processes running), and broke things trying to turn them 
off. It would be kinda cool to actually have a grasp on these kinds of 
things.
