	Technical Information	技术信息
	This page provides some background technical information on {variant-name}, including information on the core technologies used to build it, as well as the filesystem layout.	本页面提供了 {variant-name} 相关的背景技术信息，包括采用的核心技术和文件系统组织结构。
	Users should not need to know this information. It is provided here for those who are interested in the technical details or those who want to use {variant-name} in a non-standard manner.	一般用户无需了解这些信息，本页面仅为那些对 {variant-name} 实现细节感兴趣的开发者准备。
	ostree and rpm-ostree	ostree 和 rpm-ostree
	https://ostreedev.github.io/ostree/[ostree] is the core technology that is used to compose, deploy and update {variant-name}. ostree operates in a similar manner to a version control system, but it operates on entire filesystem trees. It is often described as “Git for operating system binaries”.	https://ostreedev.github.io/ostree/[ostree] 是构建、部署和更新 {variant-name} 所采用的关键技术。ostree 的工作原理和常见的版本控制系统差不多，但是 ostree 掌管的是整个文件系统目录树。我们也常常称之为『一个管理系统二进制文件的 Git 系统』。
	For {variant-name} installs, ostree is responsible for deploying and updating the OS image (including everything below `/` that is not symlinked into `/var`). It also updates `grub.cfg` entries to point to the current image.	对于 {variant-name} 而言，ostree 会被用于部署和更新系统映像（也就是 `/` 下没有被链接到 `/var` 的所有目录）。ostree 也被用于更新 `grub.cfg` 以使新系统出现在引导选单。
	https://coreos.github.io/rpm-ostree/[rpm-ostree] builds on top of ostree, and makes it possible to install RPMs as a “layer” on top of an ostree image. This makes it possible to install RPMs on {variant-name}.	https://coreos.github.io/rpm-ostree/[rpm-ostree] 基于 ostree 而来，它使得在 ostree 映像上层叠 RPM 成为可能。在 {variant-name} 安装 RPM 也是通过 rpm-ostree 实现的。
	When a package is installed with `rpm-ostree`, a new OS image is composed by adding the RPM payload to the existing OS image, and creating a new, combined image. To see the newly installed RPMs, the system needs to be rebooted with the new image. rpm-ostree also takes care of recreating the layered image whenever you update the base OS image.	当你通过 `rpm-ostree` 安装软件，层叠了有关 RPM 包的新系统映像也会随之构建。要使 RPM 安装生效，你需要重启系统以实用新的系统映像。在更新系统映像时，rpm-ostree 也会妥善处理层叠的软件包。
	{variant-name} filesystem layout	{variant-name} 文件系统组织结构
	On {variant-name}, the root filesystem (`/`) is immutable. The `/usr` directory and everything below it is read-only.	在 {variant-name}，根目录是不可变的。也就是说 `/`、`/usr` 和这些目录下的所有文件都是只读的。
	The `/etc` and `/var` directories are respectively used to store configuration files and runtime state and are thus writable. Symlinks are used to make traditional state-carrying directories available in their expected locations. This includes:	`/var` 被用于储存 {variant-name} 的运行时状态。我们使用链接使得目录能在我们期望的位置出现：
	`/home` → `/var/home`	`/home` → `/var/home`
	`/opt` → `/var/opt`	`/opt` → `/var/opt`
	`/srv` → `/var/srv`	`/srv` → `/var/srv`
	`/root` → `/var/roothome`	`/root` → `/var/roothome`
	`/usr/local` → `/var/usrlocal`	`/usr/local` → `/var/usrlocal`
	`/mnt`→ `/var/mnt`	`/mnt`→ `/var/mnt`
	`/tmp` → `/sysroot/tmp`	`/tmp` → `/sysroot/tmp`
	This means that separate home partitions should be mounted on `/var/home`.	这意味着用户目录分区应该被挂载到 `/var/home`。
	Since Fedora Linux 37, the `/sysroot` directory is also https://fedoraproject.org/wiki/Changes/Silverblue_Kinoite_readonly_sysroot[mounted read-only].
	The `/boot` and `/boot/efi` directories are currently also mounted as writable but there are plans to mount them read-only in the future or even not mount them at all. See https://gitlab.com/fedora/ostree/sig/-/issues/21[Mount /boot as Read Only by default] and https://gitlab.com/fedora/ostree/sig/-/issues/22[Do not mount /boot/efi by default].
