containers - 如何更改 podman 的 cgroup 版本

Question

我正在尝试在启用 cgroups v2 的情况下运行 podman。我找到了几篇博文，解释了如何将运行时更改为 crun，将 cgroup_manager 更改为 cgroupfs。但我不知道如何将 cgroup 版本实际设置为 v2。

我在 Manjaro Linx Kernerl 5.4 上运行 podman，所以，如果我是对的，应该支持 cgroups v2。

这里是 podman 信息的输出:

你在使用 OpenRC 吗？据我所知，您需要设置 rc_cgroup_mode="unified"在 rc.conf文件。

如果您使用 systemd，则需要运行 # grubby --update-kernel=ALL --args="systemd.unified_cgroup_hierarchy=1" .
