   1If you want to use SELinux, chances are you will want
   2to use the distro-provided policies, or install the
   3latest reference policy release from
   4        http://oss.tresys.com/projects/refpolicy
   5
   6However, if you want to install a dummy policy for
   7testing, you can do using 'mdp' provided under
   8scripts/selinux.  Note that this requires the selinux
   9userspace to be installed - in particular you will
  10need checkpolicy to compile a kernel, and setfiles and
  11fixfiles to label the filesystem.

  13        1. Compile the kernel with selinux enabled.
  14        2. Type 'make' to compile mdp.
  15        3. Make sure that you are not running with
  16           SELinux enabled and a real policy.  If
  17           you are, reboot with selinux disabled
  18           before continuing.
  19        4. Run install_policy.sh:
  20                cd scripts/selinux
  21                sh install_policy.sh
  22
  23Step 4 will create a new dummy policy valid for your
  24kernel, with a single selinux user, role, and type.
  25It will compile the policy, will set your SELINUXTYPE to
  26dummy in /etc/selinux/config, install the compiled policy
  27as 'dummy', and relabel your filesystem.
