android4.0.3关于init.c和init.rc

1.init.c是android启动的第一个进程，init.rc是init.c启动的时候加载的服务配置，init.rc最关键的地方是挂载系统分区，启动zygote虚拟机。

2.init.c的源码如下：

         * device nodes for kmsg and null, otherwise we won't
         * be able to remount / read-only later on.
         * Now that tmpfs is mounted on /dev, we can actually
         * talk to the outside world.

# This property trigger has added to imitiate the previous behavior of "adb root".
# The adb gadget driver used to reset the USB bus when the adbd daemon exited,
# and the host side adb relied on this behavior to force it to reconnect with the
# new adbd instance after init relaunches it. So now we force the USB bus to reset
# here when adbd sets the service.adb.root property to 1.  We also restart adbd here
# rather than waiting for init to notice its death and restarting it so the timing
# of USB resetting and adb restarting more closely matches the previous behavior.
