Hi guys! i-m back here and today i've just written a simple Magisk module here for all devices. This enables init.d script running after system boot systemless-ly!
How it works
• This module enables init.d script folder in /system/etc/init.d even if your kernel doesn't support it by default!
• To use it just place your script in /system/etc/init.d and set permissions 0777. This is also compatible with all performance mods zip that uses init.d scripts, like "NITRO X SPARK".
• All your script in init.d folder will be run after system boot
• Magisk v11.0+
• Busybox (Magisk in-built one is also accepted)
