kernel contains new architectural components originally developed to
improve the security of the Flask operating system. These
architectural components provide general support for the enforcement
of many kinds of mandatory access control policies, including those
based on the concepts of Type Enforcement\x{c2}\x{ae}, Role-based Access
Control, and Multi-level Security.

This package contains checkpolicy, the SELinux policy compiler.
Only required for building policies.
