Loading up modules at bootup?

apachedude · 12-01-2004, 09:01 PM

There's a module that I frequently use (visor) that I'd like the kernel to load at bootup by default. Is there a way I can configure this (preferably through YaST, but I'm willing to edit configuration files--I just don't know which files are appropriate).

The configuration file you're looking for is /etc/sysconfig/kernel. I found it myself when I needed to get the ip_conntrack_ftp module loaded for my ftp server. Add the module you want to load to the MODULES_LOADED_ON_BOOT variable.

I wasn't able to find a place to do it in YaST at the time but now I've found you can change the setting in YaST->System->/etc/sysconfig Editor. In the sysconfig editor it can be found under System->Kernel.

Cool.

Quote:

MODULES_LOADED_ON_BOOT=""

## Description: ACPI DSDT (Differentiated System Description Table)
## Type: string
## Default: ""
#
# The file name of a binary ACPI Differentiated System Description Table
# (DSDT). This table is appended to the initial ram disk (initrd) that
# the mkinitrd script creates. If the kernel finds that its initrd
# contains a DSDT, this table replaces the DSDT of the bios. If the file
# specified in ACPI_DSDT is not found or ACPI_DSDT is empty/not specified,
# no DSDT will be appended to the initrd.
# Example path /etc/acpi/dsdt

Apparently, this takes a string. Is this just the path to the module I want, because I don't know where it is. Also, what if I want to load more than one module?

Thanks for your help.

The MODULES_LOADED_ON_BOOT variable doesn't need a full path to the modules to load them. You just need to list the module names which in your case is "visor". What it doesn't say in the comments in /etc/sysconfig/kernel is that the list of modules to load is space delimited. So to load both the visor and ip_conntrack_ftp modules on boot for example you would use:

MODULES_LOADED_ON_BOOT="visor ip_conntrack_ftp"

Thank you. That's exactly what I needed.
