总括：
- 即使已启用 zfs-import-cache/zfs-mount，ZFS 池在引导期间也不会安装/导入
- 查看lsmod/journalctl，ZFS模块已经加载
- 通过运行 systemctl restart zfs-import-cache 和 systemctl restart zfs-mount 手动导入/安装 ZFS 池没有问题
这是我运行的一些控制台命令来尝试调查该问题（journalctl 命令在我重新启动服务器后仅包含 zfs 条目）

答案1
看来我需要
- 首先手动导入池（这会创建 zpool.cache）
- 启用（通过 systemctl）zfs.target、zfs-import.target、zpool-import-cache、zfs-mount
