Software design has flaws. Why do I have to provide the /etc/nginx/ directory to this program?

软件设计有缺陷，我为什么一定要提供 /etc/nginx/ 目录给到这个程序，nginx 默认已经自带了，我甚至不需要挂载 conf.d 目录

Software design has flaws. Why do I have to provide the /etc/nginx/ directory to this program? Nginx already comes with it by default, and I don't even need to mount the conf.d directory.
