5.3.1 Official Substitute Servers

ci.guix.gnu.org and bordeaux.guix.gnu.org are both front-ends to official build farms that build packages from Guix continuously for some architectures, and make them available as substitutes. These are the default source of substitutes; which can be overridden by passing the --substitute-urls option either to guix-daemon (see guix-daemon --substitute-urls) or to client tools such as guix package (see client --substitute-urls option).

URL подстановок могут быть либо HTTP, либо HTTPS. Рекомендуется HTTPS, так как такая связь шифруется; и наоборот, использование HTTP делает связь видимой для подслушивающих, и они могут использовать собранную информацию, чтобы определить, например, что ваша система не имеет патчей, покрывающих уязвимости безопасности.

Substitutes from the official build farms are enabled by default when using Guix System (see Дистрибутив GNU). However, they are disabled by default when using Guix on a foreign distribution, unless you have explicitly enabled them via one of the recommended installation steps (see Установка). The following paragraphs describe how to enable or disable substitutes for the official build farm; the same procedure can also be used to enable substitutes for any other substitute server.
