Would I change a startup service in init.rc?

I want to set up a service when amlogic Khadas VIM board powered on, so I do something below:
(1)mount -o remount,rw /
(2)vi /init.rc
(3)add a service like this in the last line:
service myshell /data/my/myshell.sh
class main
user root
group root
(4)save scucess

But when i reboot the system,the changes which i saved is lost. So,how can I solve this trouble?

Is there somthing tool for unpacking the update.img? I want to unpack the boot.img and ramdisk.img.

Hi FinalFantasy,

You can use aml_image_v2_packer to unpack update.img.

nick@Nick:~/share/VIM/server$ ls update.img 
nick@Nick:~/share/VIM/server$ mkdir out_dir
nick@Nick:~/share/VIM/server$ ~/project/khadas/ubuntu/utils/aml_image_v2_packer -d update.img out_dir

Hi numbqq,
I have unpacked update.img by aml_image_v2_packer,but the output file is not like such as boot.img system.img recovery.img and so on.

You can refer to this post. Thanks!
