一直在寻找 netfilter-persistent 将其规则存储在哪里，但在 help.ubuntu.com 上找不到任何有关它的文档。
有谁知道 Ubuntu 中的 netfilter-persistent 在哪里保存它的规则，以便它在重启后仍然存在？
我在 6 个 KVM 节点上使用 Juju GUI 部署了 Landscape 的 OpenStack Autopilot。如果升级节点的 RAM，如何在 Juju GUI 中编辑硬件详细信息？
在 MaaS GUI 中，我可以轻松编辑 CPU 核心、RAM 大小和存储大小，但 Juju GUI 仍然列出了具有旧硬件详细信息的机器。如何更新或刷新 Juju 中的硬件详细信息？
我经常发现自己在失败时重新下载相同的 lxc 实例包，并尝试使用 Landscape、单模式或多模式选项重新安装 openstack-install，这在慢速连接上需要时间。Juju 引导在下载它需要的包、实例和/或 lxc 容器时不服从系统范围的代理。幸运的是，现在手动设置 MaaS 安装，因此我们可以在 MAAS GUI 中定义 MAAS_HTTP_PROXY。
我已经设置 /etc/environment、/etc/apt/apt.conf 和 /etc/wgetrc 以在本地网络中使用代理服务器，但该工具会忽略该设置并在每次重新安装或重新部署时直接通过 Internet。
我如何配置 openstack-install 以服从系统范围的网络代理设置，以便所有下载包、实例和容器都缓存在 squid 中，以便更轻松、更快速地部署？
嗨 Ubuntu OpenStack Autopilot 团队，
虽然启用了嵌套虚拟化，但我无法在 VMware ESXi 5.5 上安装自动驾驶仪。我正在运行带有最新更新的 Ubuntu 14.04.1。
这是我尝试使用单系统模式安装时的一个：

与上面不同的错误日志有更多，但我没有保留它。如果有发现，稍后会发送更多。
关于 Ubuntu MAAS 的菜鸟问题：
- 如何制作 Ubuntu MAAS PXE 映像的本地存储库？
- 有什么软件可以做到这一点，比如apt-mirror？
- 是否有手动下载图像并将其存储在 Ubuntu MAAS 控制器上的页面？
- 下载的图片存放路径在哪里？
我想让它在本地可用，以便更快地部署 Ubuntu MAAS 并节省数据使用量。
提前致谢
我可以运行“7z -b”进行多线程基准测试，并比较 Windows 和 Linux 等平台之间的结果。但是如何在 Ubuntu 上比较单线程 7z 基准测试？:)
我在 7z -h 和http://manpages.ubuntu.com/manpages/trusty/man1/7z.1.html中没有找到关于限制 7z -b 仅在单线程中运行的文档。
我很乐意将结果与 Windows 进行比较，只是为了检查 Intel Haswell Turbo Boost 性能是否在 Ubuntu 14.04 LTS 上工作。
先谢谢了。:)
如何使用软件 RAID1 在 UEFI BIOS 上安装 Ubuntu？
每个驱动器上是否应该有 1 个 EFI 分区和另一个 RAID1（根+交换）分区？
我想知道如果它不处于 RAID1 模式，它将如何将一个 EFI 分区更新到另一个？
update-grub-efi 命令是否会仅使用 update-grub2 命令更新两个驱动器上的两个 EFI 分区，就像旧版 BIOS 中的分区一样？
我使用的是带有 Xeon E-1275 V3 处理器的 Intel Serverboard S1200V3RPL 主板。USB 安装程序被识别为 UEFI: USB 而 SSD 是 P0+P1 SSD。我假设主板像传统 BIOS 一样识别 SSD，对吗？
UEFI 或传统 BIOS 哪个更易于使用和稳定？
一直在谷歌搜索但没有运气。
