When you install ccs-tools it will automatically enable TomoyoLinux
MAC in the Manbo Core kernel. 

You need to run /usr/lib/ccs/init_policy.sh BEFORE you reboot,
or you will end up with a system that wont boot.

Running the above script can take several minutes, as it scans the
complete filesystem in order to set up an initial policy that will
allow your system to boot and work correctly.

We suggest that you read the online kickstart manual:

to get a better understanding of the system.
