如何更改核心图像最小yocto中的init系统 [英] How to change the init system in core-image-minimal yocto

问题描述

我想基于 core-image-minimal 创建一个新目标，并且我想通过 SysV init .我希望我的更改是永久的(不基于local.conf).我该怎么办?

I would like to create a new target based on core-image-minimal and I would like to change the init system with systemd over SysV init. I would like my change to be permanent (nothing based on local.conf). How can I do this?

推荐答案

正如安德斯(Anders)在评论中指出的那样，我错了:

As Anders pointed out in the comments, i was wrong:

可用的初始化系统在local.conf中设置，但是您确实可以基于每个映像更改初始化系统.在您的情况下，您想在 core-image-minimal 中进行更改.该映像将安装 packagegroup-core-boot ，该设置会设置

The available init systems are set in the local.conf, but you can indeed change the init system on a per image basis. In your case you want to change it in core-image-minimal. This image installs packagegroup-core-boot which sets

VIRTUAL-RUNTIME_init_manager ?= "sysvinit"
VIRTUAL-RUNTIME_initscripts ?= "initscripts"

您可以创建自己的 packagegroup-core-boot-systemd ，将这些变量设置为

You could create your own packagegroup-core-boot-systemd where those variables are set to

VIRTUAL-RUNTIME_init_manager = "systemd"
VIRTUAL-RUNTIME_initscripts = ""

并将其安装到目标.

init系统的配置是发行功能.这意味着它不在图像配方中，而在local.conf中.

The configuration of the init system is a Distro Feature. That means it is not in the image recipe, but in the local.conf.

如果您不想将配置放入local.conf中，则可以使用其中的设置来创建自定义发行版配置.您只需在local.conf中更改的是该行

If you don't want to put the configuration in the local.conf, you could create a custom distro configuration with the settings in it. The only thing you have to change in the local.conf is the line

# DISTRO = poky
DISTRO = <custom-distro>

参考手册还在创建自己的发行版

The reference manual has also a chapter on creating your own distro
