在 Yocto 构建中禁用标准 systemd 服务 [英] Disable a standard systemd service in Yocto build

问题描述

我需要启动我自己的systemd 服务，我们称之为custom.service.我知道如何编写一个在启动时添加和启用它的方法:

I need to start my own systemd service, let's call it custom.service. I know how to write a recipe for it to be added and enabled on boot:

SYSTEMD_SERVICE_${PN} = "custom.service"
SYSTEMD_AUTO_ENABLE_${PN} = "enable"

但是，它与默认的 systemd 服务之一 - systemd-timesyncd.service 冲突.

However, it conflicts with one of the default systemd services - systemd-timesyncd.service.

即使 systemd_XX.bb 实际启用它，是否有一个很好的首选方法来禁用我的 bitbake 文件中的默认 systemd 服务?

Is there a nice preferred way to disable that default systemd service in my bitbake file even though the systemd_XX.bb actually enables it?

我可以创建一个 systemd_%.bbappend 文件来修改 systemd 设置，但是我找不到可以禁用一项服务而启用所有其他服务的位置.

I can create a systemd_%.bbappend file to modify the systemd settings, but I can't locate the place where one service can be disabled leaving all others enabled.

我发现的工作解决方案是使用

The working solution I found is to remove the timesyncd altogether using

PACKAGECONFIG_remove = "timesyncd"

但我想知道这是否是一种合适的方式，是否有一种方法可以禁用它，但留在系统中.

But I wonder if this is a appropriate way and if there is a way to just disable it, but leave in the system.

推荐答案

如果系统在移除其他包后运行良好，则移除包是首选解决方案.更少的包意味着更简单的系统.

If the system runs fine with the other package removed, then removing the package is a preferred solution. Fewer packages means a simpler system.
