So yea I've been working on a proper "app2sd" solution that doesn't involve just switching the MicroSD for the eMMC, but I like the stock rom so far, so I didn't feel like flashing a rom just to get init.d, and I didn't feel like modifying the ramdisk in the kernel either. So I cooked up this script that anyone can run from terminal to get init.d support. It should work for other devices too, as long as they run /system/etc/install-recovery.sh on boot.
There's only three requirements for it to work:
#1 You must be rooted
#2 Your device must run /system/etc/install-recovery.sh
#3 You must have busybox
I tested a few times on my own device (GT-N8013), but haven't had anyone else test it, so don't freak out if it doesn't work. Just let me know what went wrong and I'll figure something out.
Running it is very simple:
#1 Open any terminal app
#2 su
#3 navigate to the folder where you have the script
#4 sh ./enableinit.sh
Your device will be rebooted once the process is done, don't freak out. If everything went fine, you'll have a file in /sdcard called init.d.log created by the test init.d script that is made by the enabler.
You can either download the attachment (rename it to enableinit.sh if you get the attachment), or create the file with the contents betlow:
