5.5 Specifying Modules to be Loaded at Boot Time

The following lines in /etc/rc.sysinit defines how the init process runs scripts in the /etc/sysconfig/modules directory at boot time:

# Load other user-defined modules
for file in /etc/sysconfig/modules/*.modules ; do
  [ -x $file ] && $file
done

To load a module at boot time:

Create a file in the /etc/sysconfig/modules directory. The file name must have the extension .modules, for example foo.modules.
Edit the file to create the script that loads the module.
The script to load a module can be a simple modprobe call, for example:
```
#!/bin/sh
modprobe foo
```
or more complex to include error handling:
```
#!/bin/sh
if [ ! -c /dev/foo ] ; then
  exec /sbin/modprobe foo > /dev/null 2>&1
fi
```
Use the following command to make the script executable:
```
# chmod 755 /etc/sysconfig/modules/foo.modules
```
