I was thinking that since init.rc or init.device.rc would be built into the ROM, the features(the different parts of code that was init.rc) in init.device.rc has to be somewhere in ROM, even separated into different parts. Everything that was in the source gets baked into the ROM, the question is just, where is init.rc now or where are the features implemented now. I've seen parts init.device.rc all through the ROM, I just don't know the where all of them are...
