After the recent discussion on Ale regarding the security of kernel
modules, I thought this excerpt from the new Red Hat beta's readme was
interesting:

----
The Red Hat Linux 9.0.93 kernel now makes it possible to prevent the
loading of kernel modules. This can be useful for system administrators
wanting to ensure that only a strictly-controlled set of modules are
loaded. To disable kernel module loading, issue the following command:

echo off > /proc/modules

Once this command has been issued, all further attempts to load kernel
modules will fail.

NOTE: Once kernel module loading has been disabled, a reboot is required
to re-enable it.
