reiserfs support for SELinux (/etc/security/selinux/src/policy/Makefile)

Makefile (text/plain), 5.97 KB, created by Tetsuji Rai on 2006-05-16 00:47:02 UTC

#
# Makefile for the security policy.
#
# Targets:
# 
# install - compile and install the policy configuration.
# 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.
# policy  - compile the policy configuration locally for testing/development.
#
# The default target is 'install'.
#

# Set to y if MLS is enabled in the module.
MLS=n

# Uncomment if you want to generate policy file compatible with older
# kernels.
#POLICYCOMPAT = -c 15
