Delete program, file and lines related to modules

By default when you install Red Hat Linux for the first time (like we do), the kernel is built as a modularized kernel. This means that each device or function we need exists as modules and is controlled by the Kernel Daemon program named kmod, which automatically loads some modules and functions support into memory as it is needed, and unloads it when it’s no longer being used.

The Openwall patch is a collection of security-related features for the Linux kernel, all configurable via the new “‘Security options” configuration section that will be added to your new Linux kernel. This patch may change from version to version, and some may contain various other security fixes. (Далее…)

The Linux kernel is the core of our operating system, and without it there is no Linux at all. So we must take care of our kernel and configure it to fit our needs and compile just features we really need. (Далее…)
