# SELinux policy for LXC for RHEL/CentOS/Oracle 6.5.
# It attempts to restrict the container to the same amount of access
# as an unprivileged user. To build and insert this policy module:
#
# make -f /usr/share/selinux/devel/Makefile lxc.pp
# semodule -i lxc.pp
#
# In your container's lxc config:
# lxc.se_context = system_u:system_r:lxc_t:s0:c62,c86,c150,c228
#
# Ensure your container's rootfs files are labeled:
# chcon -R system_u:object_r:lxc_file_t:s0:c62,c86,c150,c228 /path/to/rootfs
#
# To keep containers separated from each other, you should vary the MCS
# portion of the contexts above to be a unique set of values for each
# container, each MCS compartment can be a number from 0-1023.
