Well, to be fair, I saw the original method that said to do it using sqlite editor apk, then manually f/c the services. I then took and handwrote the original commands I posted a few days ago...then in this ROM, took and changed "INSERT INTO" to "INSERT OR UPDATE" after seeing okibi do it, realizing that would account for it already being there.
Either way, it's a bloody brilliant idea that wasn't mine to begin with, and I'm happy to give whomver credit for it. Now if I could only make it work from init.d.
Rename debuggerd in /system/bin to debuggerd.orig and make a shell script (named debuggerd) to call debuggerd.orig then whatever commands you want to run.
Debuggerd runs on boot, so the script (as well as the original debuggerd by calling debuggerd.orig) will be executed every boot.
EDIT: Look here. Thanks, @JustArchi.
