	This section discusses third-party software sources not officially affiliated with or endorsed by the Fedora Project. Use them at your own discretion.
	If you want to use RPM Fusion repositories, please follow the xref:tips-and-tricks.adoc#_enabling_rpm_fusion_repos[Enabling RPM Fusion repos] section.
	Some sofware may only be available from a third-party repository. You can add an external repository manually on {variant-name} by placing the `.repo` file into `/etc/yum.repos.d/` and the GPG key into `/etc/pki/rpm-gpg/`. The following is a full example for setting up the Tailscale repo:
	Fetch and install the repo config:
	$ curl -O https://pkgs.tailscale.com/stable/fedora/tailscale.repo [tailscale-stable] name=Tailscale stable baseurl=https://pkgs.tailscale.com/stable/fedora/$basearch enabled=1 type=rpm repo_gpgcheck=1 gpgcheck=0 gpgkey=https://pkgs.tailscale.com/stable/fedora/repo.gpg $ sudo install -o 0 -g 0 -m644 tailscale.repo /etc/yum.repos.d/tailscale.repo
	Fetch and install the GPG keys:
	$ curl -O https://pkgs.tailscale.com/stable/fedora/repo.gpg $ sudo install -o 0 -g 0 -m644 repo.gpg /etc/pki/rpm-gpg/tailscale.gpg
	Replace the `gpgkey=` URL in the repo config by the path the GPG keys:
	$ sudo $EDITOR /etc/yum.repos.d/tailscale.repo $ cat /etc/yum.repos.d/tailscale.repo [tailscale-stable] name=Tailscale stable baseurl=https://pkgs.tailscale.com/stable/fedora/$basearch enabled=1 type=rpm repo_gpgcheck=1 gpgcheck=0 # Update this line gpgkey=file:///etc/pki/rpm-gpg/tailscale.gpg # ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
	Install the new packages with:	安装软件包到 `/opt` 或 `/usr/local`
	$ rpm-ostree install tailscale
	Better support in `rpm-ostree` for this use case is tracked in https://github.com/coreos/rpm-ostree/issues/4014[rpm-ostree#4014].	https://github.com/projectatomic/rpm-ostree/issues/233[GitHub Issue]
	SELinux problems	SELinux 相关问题
	As users work with {variant-name} day-to-day, it is possible that they have modified the default SELinux policy in an effort to workaround one or more problems related to SELinux. This is usually done when a user sees a SELinux denial in the journal. If this is the case and one wishes to revert back to the default SELinux policy, you can try these set of actions.	有些 {variant-name} 用户可能希望临时修改默认的 SELinux 策略，以解决与 SELinux 相关的问题。如果在修改后又希望恢复到默认的 SELinux 策略，则可以尝试下面的操作。
	Check the state of the SELinux policy	查看当前的 SELinux 策略
	$ sudo ostree admin config-diff \| grep policy M selinux/targeted/active/policy.linked M selinux/targeted/active/policy.kern M selinux/targeted/policy/policy.31 A selinux/targeted/policy/policy.30	$ sudo ostree admin config-diff \| grep policy M selinux/targeted/active/policy.linked M selinux/targeted/active/policy.kern M selinux/targeted/policy/policy.31 A selinux/targeted/policy/policy.30
	If anything is returned by this command, then your SELinux policy has been modified from the default.	如果执行这个命令有任何输出，那就意味着 SELinux 策略有被改动过。
	Copy the default SELinux policy shipped in the OSTree compose	复制 OSTree 构建提供的 SELinux 默认策略
	$ sudo cp -al /etc/selinux{,.bak} $ sudo rsync -rlv /usr/etc/selinux/ /etc/selinux/	$ sudo cp -al /etc/selinux{,.bak} $ sudo rsync -rlv /usr/etc/selinux/ /etc/selinux/
	After doing this, the output from `ostree admin config-diff \| grep policy` should no longer indicate the policy is modified.	此时执行 `ostree admin config-diff \| grep policy` 应该不会再有输出，也就意味着 SELinux 策略恢复成功。
	If your policy still appears to be modified, you can try the following approach.	如果恢复没有成功，还可以尝试下面的方法。
	Remove the SELinux policy; copy in the default policy	移除已有 SELinux 策略；添加默认策略
	$ sudo rm -rf /etc/selinux $ sudo cp -aT /usr/etc/selinux /etc/selinux	$ sudo rm -rf /etc/selinux $ sudo cp -aT /usr/etc/selinux /etc/selinux
	After this, the `ostree admin config-diff \| grep policy` command should return no modifications.	此时执行 `ostree admin config-diff \| grep policy` 应该不会再有输出。
	Unable to add user to group	无法将用户添加到用户组
	Due to how `rpm-ostree` handles user + group entries, it may not be possible to use `usermod -a -G` to add a user to a group successfully. Until `rpm-ostree` moves to using `systemd sysusers`, users will have to populate the `/etc/group` file from the `/usr/lib/group` file before they can add themselves to the group.	由于 `rpm-ostree` 的原因，`usermod -a -G` 是无法将用户添加到用户组的。在 `rpm-ostree` 使用 `systemd sysusers` 之前，用户必须先按照 `/usr/lib/group` 填写 `/etc/group`，然后才能将自己添加到组中。现在假设要将用户添加到 `libvirt` 组：
	For example, if you wanted to add a user to the `libvirt` group:
	$ grep -E '^libvirt:' /usr/lib/group \| sudo tee -a /etc/group $ sudo usermod -aG libvirt $USER	# grep -E '^libvirt:' /usr/lib/group >> /etc/group # usermod -aG libvirt username
	You will need to log off and log back in to apply these changes.	你需要注销并重新登录来应用这些更改。
	This issue is tracked in https://github.com/coreos/rpm-ostree/issues/29[rpm-ostree#29] and https://github.com/coreos/rpm-ostree/issues/49[rpm-ostree#49].
