I'm trying to run a script that exectues when the device has finished booting. This particular device does not support running scripts from an init.d directory, which is why I am using init.rc.

The init.rc file has been modified to include the following code

on property:sys.boot_completed=1
start initAsic

service initAsic /data/local/tmp/runn.sh
user root
group root
oneshot

The boot image has then been rebuilt and flashed to the device. The changes can be confirmed by viewing the init.rc file located at /

Currently I am only using a simple test script (testScript.sh) which issues the following command 

echo hi >> /data/local/tmp/test.txt

The testScript.sh and text.txt file has 777 permissions set and both have been pushed to the device using adb push. Their current location is /data/local/tmp/

For some reason it seems that my script is not running, as I can't see any text being written to test.txt.

Am I missing something? Could it be an issue with SELinux?

My device currently has SElinux set to permissive. This was done via altering the BoardConfig.mk file and doing a rebuild of the boot.img.

By running the command dmesg | grep -C5 initAsic I saw that I was getting this error code returned

service initAsic does not have a SELinux domain defined

The issue what that I needed to add the line seclabel u:r:init:s0 to my init service as this is a requirement of init. The complete service now looks like this. The disabled keyword has also been added as suggested by Irfan. 

service initAsic2 /data/local/tmp/runn.sh
seclabel u:r:init:s0
user root
group root
oneshot
disabled

Also note that SElinux must be set to permissive to allow this service to run or preferably - as setting SElinux to permissive is a security risk - defining the appropriate rules for SElinux and using the modified policy.

This post was where I found the suggestion to add seclabel property. It also has more useful information regarding the SELinux issue I was encountering: https://stackoverflow.com/questions/43600261/init-warning-service-myservice-needs-a-selinux-domain-defined-please-fix
