# 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'.
