android boot - where is the init.%hardware%.rc read in init.c ? where are services started?

Question

Going through the code in init.c and trying to figure out 2 things:

• Where is the hardware specific init.%hardware%.rc read ?

• Where are the services started - meaning zygote, /system/bin/servicemanager etc

An example of an init.%hardware%.rc would be appreciated.

Answer 1

Ok got it - both questions are answered in init.rc.

• hardware specific init.%hardware%.rc read at http://androidxref.com/4.3_r2.1/xref/system/core/rootdir/init.rc#8, where we see the line

  import /init.${ro.hardware}.rc
  

  Now, ro.hardware is read from the command line (main, process_kernel_cmdline and finally export_kernel_boot_props). Where is the command line, well...

• Services started: in main the boot action is triggered, which contains the lines

  class_start core
  class_start main
  

  that start all the core and main services. Got the info from Where are the Android system services started?

NB: I refer to KitKat - YMMV
