Linux SystemD服务-简单vs分叉-缺点？

Question

A lot of programs you download can be run in a blocking manner or in the background (usually by start/stop/etc commands). Some good examples are HA Proxy and Spring Boot apps built to be Linux services... both can be run in either manner.

In system-d unit files you can use "forked" type to allow you to map to start/stop/etc commands for managing a program that runs in the background/as a daemon. Alternatively, you can just use the "simple" type and call the app itself in a blocking manner.

Is there any particular reason to prefer "forked" where it is an option? Having done both options on numerous things, it seems "simple" is lighter on config and more obvious in terms of usage.

这可以在https://www.freedesktop.org/software/systemd/man/daemon.html “ sysv守护程序”部分中得到解答，选择“分叉”方法主要只有缺点，因为那里的大多数软件都不会执行“ 15个步骤”是正确地还是根本没有，特别是很少正确地执行步骤12和14。
