Kernel modules are usually loaded directly by the facility that
requires them, which is given correct settings in the /etc/modprobe.conf file. However, it is sometimes
necessary to explicitly force the loading of a module at boot
time.
Red Hat Enterprise Linux checks for the existence of the
/etc/rc.modules file at boot time, which
contains various commands to load modules. The rc.modules should be used, and not rc.local because
rc.modules is executed earlier in the
boot process.
For example, the following commands configure loading of the
foo module at boot time (as root):
# echo modprobe foo >> /etc/rc.modules
# chmod +x /etc/rc.modules

This approach is not necessary for network and SCSI interfaces
because they have their own specific mechanisms.
