3.4 Installation Overview

The procedure for
installing SELinux varies according to
the target Linux distribution. However, it generally includes the
following operations:

Configuration, compilation, and installation of a kernel supporting
SELinux

Modification of the bootloader configuration to include the new,
SELinux-capable kernel

Installation and configuration of SELinux-related userland libraries,
utilities, and commands

Compilation and installation of an SELinux policy

Labeling of the filesystems

The operations can be performed in any of a variety of sequences. A
few of these operations can be entirely omitted if precompiled
packages are used. And additional operations are generally required,
as explained in the following sections.
