loading modules at boot

Davidian1024 · 06-22-2004, 08:33 PM

I recently finished building an LFS system. I followed the instructions in LFS-5.1 as closely as I could. Now that it boots and everything I wanted to try using a modular setup. I wanted to load certain modules at boot but I can't seem to get this to work like I think it should. A couple of options look like they would work but neither seem to do anything.

First I tried putting symlinks to the modules in question in the /lib/modules/boot directory.

Then I tried putting the names of the modules in a text file called modules in the /etc directory.

Neither method seems to do anything. Once I've logged in as root I run lsmod and those modules are not present.

Have you tried using a bootscript to load the modules?

#!/bin/bash
modprobe $MODULE

The book describes how the bootscripts work.

Well, I was hoping I wouldn't have to do it that way. Maybe I'm being stupid but I didn't really want to mess around with the boot scripts just yet.

HI,
for loading modules where the file is doesn't really matter
i will give you step by step since you feel uncomfortable
i created a file
/etc/rc.d/init.d/modules

Code:

#!/bin/bash

# Initialize Modules


modprobe  someModule
modprobe  anotherModule

chmod 755 /etc/rc.d/init.d/modules
then at the bottom of /etc/rc.d/init.d/rc

just put

Code:

/etc/rc.d/init.d/modules

that's it
everything is copasetic now

might help to have a /etc/modules.conf file
you can try to generate one if you don't have one at all with(as root)
cd /etc
modprobe -c >modules.conf

this will hopefully create a beginning to a working file that will need editing
(you can also try useing the one from your starting OS if the kernel version is simmilar)
or you can leave it out and see how you do without it
