如何在 root 上配置 ZFS 的自动安装

我尝试自动安装 ubuntu 服务器，提供文档中所述的用户数据文件，但具体来说是针对 Virtualbox 上 ZFS 上的 root。我按照 cloud-init 文档设置用户数据文件的存储部分。我实现了文档中显示的“ZFS Root Simple”和“ZFS Root”示例。简单的一个可以正常工作，但第二个不起作用，弹出的 subiquity 错误是“自动安装配置未挂载 root”。我无法弄清楚配置有什么问题，尽管它来自文档。

配置文件如下所示：

#cloud-config

    hostname: ubuntu-server

您可以在 中找到有关错误消息的更多详细信息/var/log/curtin/installer.log。我使用此自动安装配置取得了很大进展。仅在 proxmox VM 中对其进行了测试，因此 ymmv。

我遇到了同样的问题，看来这个问题应该在下一版本的 subuquity Ubuntu Server 安装程序中得到修复。当检查 root 是否已挂载时，zpool如果mountpoint是，它现在将接受存储类型对象/。

看这里 (0e1da11c3)对于来自项目存储库的此更改的提交：https://github.com/canonical/subiquity。
