/etc/portage/repos.conf 指定当前系统使用的存储库的位置和设置。它可以是单个文件，也可以是一个或有多个 .conf 文件的目录。它指的是 Gentoo 存储库以及系统上使用的附加 ebuild 存储库。

If /etc/portage/repos.conf/gentoo.conf does not exist, defaults from /usr/share/portage/config/repos.conf will be used. This removes the need to create /etc/portage/repos.conf/gentoo.conf manually, which is not recommended by the Handbook anymore.

If some necessary settings, such as sync-uri are omitted from /etc/portage/repos.conf/gentoo.conf, values from /usr/share/portage/config/repos.conf will be used. Some values, such as priority, will be automatically added by Portage even if they are not present in any configuration file.

提示
eselect-repository is a handy tool for configuring repositories without editing /etc/portage/repos.conf by hand.

附注
See the /etc/portage/repos.conf section in man 5 portage for detailed information about the format and parameters of repos.conf.

Manage repositories

Add, disable, or remove ebuild repositories using eselect repository, which also provides other functionality.

It is also possible to add a repository by manually creating files in /etc/portage/repos.conf, see the appropriate section of the Handbook (other reference).

Files in /etc/portage/repos.conf can be edited with a text editor to change the configuration options for an ebuild repository.

List repositories

要显示所有配置了 portage 的软件库，请运行 portageq：

Ebuild repository priority

To set the priority of a certain repository, manually edit the relevant repos.conf section and set priority = to the desired value. The higher the set value, the higher the priority. For example:

文件 /etc/portage/repos.conf/eselect-repo.confSet priority of a repository

# created by eselect-repo
  
[guru]
location = /var/db/repos/guru
sync-type = git
sync-uri = https://github.com/gentoo-mirror/guru.git
priority = 100

Repositories that do not have a priority explicitly set, default to 0 - except the Gentoo ebuild repository, which defaults to to a value of -1000.

Alternative sync protocols

See the Portage with Git article for how to sync the ::gentoo ebuild repository using git as an alternative to the traditional rsync protocol.
