How to completely disable SELinux in Android L in the init.rc file

I want to disable SELinux at boot time for Android L or 5. The reason is because my daemon is not begin executed on boot when it should due to SELinux problems. I have the following in my init.rc file:

su 0 setenforce 0
service my_daemon /system/bin/my_daemon 
    class main     # Also tried: class core (but it didn't make a difference)
    user root
    group root

However, on boot, I use adb shell to check if SELinux is disabled (using getenforce) and it returns Enforcing. I want SELinux to be completely disabled on boot. If not completely disabled then at least Permissive.

Any suggestions?
