Appendix D. Default init.rc Files

This appendix contains the default init.rc files found in 2.3/Gingerbread and 4.2/Jelly Bean.^[38] I usually dislike books where files are printed for pages on end, and you won’t find much of this in my writings. However, init.rc is one case where the best way to explain something is to actually show it to you. To make it easier for you to follow the operations conducted in the file, I’ve added some callouts throughout to provide insight on key parts of the files. Refer to Chapter 6 for more information regarding the actions, triggers, commands, services, and service options used in init.rc files.
