Your partly right.
However, they'd still have to load during bootup, then they'd get removed
as a final step in /etc/rc.d/rc.local. I think what Mark wanted (Mark,
please correct me if I'm wrong) is not to load them in the first place, so
that bootup happens faster.
that`s what i want indeed.
I'm far, far away from being any kind of an expert on Linux use of modules,
but isn't it true that modules only get loaded if they are needed? So, if
Mark goes through all the startup services (in chkconfig, or
system-config-services) and disables all the ones he doesn't want or need
(which will probably be a lot of them), won't that result in modules not
getting loaded that are assocuated with the eliminated startup processes?
That`s partly right.
i did remove all the services that i didn`t want but the loaded module list is still the same.
i even removed all the modprobe files and it`s still exactly the same. (rm -rf /etc/modprobe*) (actually moved them to my personal folder.. /home/mark)
This is the list of modules that i have:

Now all the modules that have: "Used By 0" can be thrown away because nothing is using it.
that`s what i want. i don`t want to load the modules first and unload them at the end of the boot progress (that doesn`t speed up the boot progress but slows it down).
please tell me that it`s possible without recompiling the kernel :) (if not.. that will take serveral hours)
any ideas?

Good morning, Nigel.
However, they'd still have to load during bootup, then they'd get removed
as a final step in /etc/rc.d/rc.local. I think what Mark wanted (Mark,
please correct me if I'm wrong) is not to load them in the first place, so
that bootup happens faster.
(I seem to vaguely recall that part of an early mission statement for F7
was to not load eleventy-gazillion processes and modules on bootup, so that
bootup would happen faster... looks like that was one of the objectives
that had to be deferred...)
I'm far, far away from being any kind of an expert on Linux use of modules,
but isn't it true that modules only get loaded if they are needed? So, if
Mark goes through all the startup services (in chkconfig, or
system-config-services) and disables all the ones he doesn't want or need
(which will probably be a lot of them), won't that result in modules not
getting loaded that are assocuated with the eliminated startup processes?
I'd be wary of using /etc/rc.d/rc.local to remove modules previously
loaded... they were loaded for a reason after all...
