I have an android device.. and Honor View 10... L04 version (US). I have a set of tweaks I am injecting into my kernels ramdisk, that all fire off without issue when I adb shell in and manually run them.
The issue I am finding, is when I setup the services to run in a *.rc file, I am getting a "Permission Denied" error on all of them.

I am assuming my seclabels are incorrect, but I'm not 100% sure about that.
What can I do to fix this, so my scripts run properly?
UPDATE
Changerd the seclabel to seclabel u:r:init:s0, and now my error log changed... so I think I'm getting on the right track....
