#

# Makefile for the security policy.

#

# Targets:

# 

# install       - compile and install the policy configuration, and context files.

# load          - compile, install, and load the policy configuration.

# reload        - compile, install, and load/reload the policy configuration.

# relabel       - relabel filesystems based on the file contexts configuration.

# checklabels   - check filesystems against the file context configuration

# restorelabels - check filesystems against the file context configuration

#                 and restore the label of files with incorrect labels

# policy        - compile the policy configuration locally for testing/development.

#

# The default target is 'policy'.

# Configurable portions of the Makefile

#

# Policy version

# By default, checkpolicy will create the highest

# version policy it supports.  Setting this will

# override the version.

#OUTPUT_POLICY = 18

# Policy Type

# strict, targeted,

# strict-mls, targeted-mls,

# strict-mcs, targeted-mcs

TYPE = strict

# Policy Name

# If set, this will be used as the policy

# name.  Otherwise the policy type will be

# used for the name.

NAME = refpolicy

# Distribution

# Some distributions have portions of policy

# for programs or configurations specific to the

# distribution.  Setting this will enable options

# for the distribution.

# redhat, gentoo, debian, and suse are current options.

# Fedora users should enable redhat.

#DISTRO = redhat

# Direct admin init

# Setting this will allow sysadm to directly

# run init scripts, instead of requring run_init.

# This is a build option, as role transitions do

# not work in conditional policy.

# This option will be impled as y for redhat policies.

DIRECT_INITRC=n

# Build monolithic policy.  Putting n here

# will build a loadable module policy.

MONOLITHIC=y

# Uncomment this to disable command echoing
