5If you want to use SELinux, chances are you will want
6to use the distro-provided policies, or install the
7latest reference policy release from
8
9	https://github.com/SELinuxProject/refpolicy
10
11However, if you want to install a dummy policy for
12testing, you can do using ``mdp`` provided under
13scripts/selinux.  Note that this requires the selinux
14userspace to be installed - in particular you will
15need checkpolicy to compile a kernel, and setfiles and
16fixfiles to label the filesystem.
17
18	1. Compile the kernel with selinux enabled.
19	2. Type ``make`` to compile ``mdp``.
20	3. Make sure that you are not running with
21	   SELinux enabled and a real policy.  If
22	   you are, reboot with selinux disabled
23	   before continuing.
24	4. Run install_policy.sh::
25
26		cd scripts/selinux
27		sh install_policy.sh
28
29Step 4 will create a new dummy policy valid for your
30kernel, with a single selinux user, role, and type.
31It will compile the policy, will set your ``SELINUXTYPE`` to
32``dummy`` in ``/etc/selinux/config``, install the compiled policy
33as ``dummy``, and relabel your filesystem.
