如何启用 systemd 支持 [英] How to enable systemd support

问题描述

我已经构建了一个支持 systemd 的 Yocto 2.4.2 系统.但是我的配置中似乎遗漏了一些问题，导致内核启动失败.有人可以帮忙吗?

I have built a system with Yocto 2.4.2 supporting systemd. But there are some issues seemed to be missed in my configurations leading to failure of kernel starting. Any one can help ?

  DISTRO_FEATURES_append = " systemd"
  VIRTUAL-RUNTIME_init_manager = "systemd"

推荐答案

systemd 和 cgroup 应该一起启用

• systemd 管理器 (local.conf)

• systemd manager (local.conf)

DISTRO_FEATURES_append = "systemd"

DISTRO_FEATURES_append = " systemd"

VIRTUAL-RUNTIME_init_manager = "systemd"

VIRTUAL-RUNTIME_init_manager = "systemd"

对于 systemd 处理程序 (defconfig)

For systemd handler (defconfig)

CONFIG_FHANDLE=y #for systemd

CONFIG_FHANDLE=y #for systemd

systemd (defconfig) 需要 cgroups

cgroups is required by systemd (defconfig)
