Img 生成脚本：
target/hypervisor/host/create_images.sh
tools/build/image-builder.sh
The QVM config file for the guest is instantiated within the host rootfs build file, located at root/target/hypervisor/qvm/$project/build_files/system.build.tmpl
startup.sh
Based on the requirements, services that are not critical to boot, can be launched programmatically using startup script.
Script location is under: /qnx_ap/target/hypervisor/host/startup.qvmhost.tmpl
target/hypervisor/host/create_images.sh +898
将startup.qvmhost.tmpl拷贝到out目录下更名为startup-qvmhost.sh
target/hypervisor/host/out_8540/system.build_la +990
将startup-qvmhost.sh放到/sritpts/startup中
编译后生成的startup脚本
Qnx 的宏定义都在这个脚本中：
target/hypervisor/host/out_8540/platform_variables.sh
startupmgr
qnx_ap/target/hypervisor/host/startupmgr/src/script.c
build_files/makena_qdrive_mifs.build.tmpl
