Raw Blame History

#
# 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.
DIRECT_INITRC=n
# Build monolithic policy. Putting n here
# will build a loadable module policy.
MONOLITHIC=y
# Uncomment this to disable command echoing
