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?

Instead of putting in init.rc you can make it permissive by adding some parameters to kernel command line (BOARD_KERNEL_CMDLINE)

Ex: Add enforcing=0 androidboot.selinux=permissive in device/<manufacturer>/<target>/BoardConfig.mk
