selinux

I have a bootable DVD which boots the same Kernel as the Hard Drive (which uses SELinux). I have copied /etc/selinux and all the kernel modules to my ramdisk, and have tried both selinux=1 and selinux 1 as Kernel boot parameters.

After the system boots, I check dmesg:

% dmesg | grep -i selinux
Kernel command line: initrd=idrd.img ramdisk_size=110476 selinux=1
SELinux: Initializing.
SELinux: Starting in permissive mode
selinux_register_security: Registering secondary module capability
SElinux: Registering netfilter hooks

But SELinux isn't running:

% /usr/sbin/getenforce
Disabled
% /usr/sbin/setenforce 1
/usr/sbin/setenforce: SELinux is disabled

/var/log/messages does not hold any clues. /proc/kmsg also has nothing
