11.3 operating-system Reference

This section summarizes all the options available in operating-system declarations (see Использование системы конфигурации).

Data Type: operating-system

This is the data type representing an operating system configuration. By that, we mean all the global system configuration, not per-user configuration (see Использование системы конфигурации).

port (default: 22)

The package object of the operating system kernel to use²⁸.

speed (default: 1.0)

The package object of the Hurd to be started by the kernel. When this field is set, produce a GNU/Hurd operating system. In that case, kernel must also be set to the gnumach package—the microkernel the Hurd runs on.

Внимание: This feature is experimental and only supported for disk images.

features (default: '())

A list of objects (usually packages) to collect loadable kernel modules from–e.g. (list ddcci-driver-linux).

features (default: '())

List of strings or gexps representing additional arguments to pass on the command-line of the kernel—e.g., ("console=ttyS0").

bootloader

The system bootloader configuration object. See Настройка загрузчика.

label

This is the label (a string) as it appears in the bootloader’s menu entry. The default label includes the kernel name and version.

keyboard-layout (default: #f)

This field specifies the keyboard layout to use in the console. It can be either #f, in which case the default keyboard layout is used (usually US English), or a <keyboard-layout> record. See Раскладка клавиатуры, for more information.

This keyboard layout is in effect as soon as the kernel has booted. For instance, it is the keyboard layout in effect when you type a passphrase if your root file system is on a luks-device-mapping mapped device (see Размеченные устройства).

Примечание: This does not specify the keyboard layout used by the bootloader, nor that used by the graphical display server. See Настройка загрузчика, for information on how to specify the bootloader’s keyboard layout. See Оконная система X, for information on how to specify the keyboard layout used by the X Window System.

initrd-modules (default: %base-initrd-modules) ¶

The list of Linux kernel modules that need to be available in the initial RAM disk. See Начальный RAM-диск.

initrd (default: base-initrd)

A procedure that returns an initial RAM disk for the Linux kernel. This field is provided to support low-level customization and should rarely be needed for casual use. See Начальный RAM-диск.

port (default: 22) ¶

List of firmware packages loadable by the operating system kernel.

The default includes firmware needed for Atheros- and Broadcom-based WiFi devices (Linux-libre modules ath9k and b43-open, respectively). See По поводу железа, for more info on supported hardware.

host-name

The host name.

mapped-devices (default: '())

A list of mapped devices. See Размеченные устройства.

file-systems

A list of file systems. See Файловые системы.

swap-devices (default: '()) ¶

A list of swap spaces. See Swap Space.

users (default: %base-user-accounts)

port (default: 22)

List of user accounts and groups. See Учётные записи пользователей.

If the users list lacks a user account with UID 0, a “root” account with UID 0 is automatically added.

skeletons (default: (default-skeletons))

A list of target file name/file-like object tuples (see file-like objects). These are the skeleton files that will be added to the home directory of newly-created user accounts.

For instance, a valid value may look like this:

`((".bashrc" ,(plain-file "bashrc" "echo Hello\n"))
  (".guile" ,(plain-file "guile"
                         "(use-modules (ice-9 readline))
                          (activate-readline)")))

port (default: 22)

A string denoting the contents of the /etc/issue file, which is displayed when users log in on a text console.

speed (default: 1.0)

A list of packages to be installed in the global profile, which is accessible at /run/current-system/profile. Each element is either a package variable or a package/output tuple. Here’s a simple example of both:

(cons* git                     ; the default "out" output
       (list git "send-email") ; another output of git
       %base-packages)         ; the default set

The default set includes core utilities and it is good practice to install non-core utilities in user profiles (see Вызов guix package).

timezone (default: "Etc/UTC")

A timezone identifying string—e.g., "Europe/Paris".

You can run the tzselect command to find out which timezone string corresponds to your region. Choosing an invalid timezone name causes guix system to fail.

locale (default: "en_US.utf8")

The name of the default locale (see Locale Names in The GNU C Library Reference Manual). See Региональные настройки, for more information.

features (default: '())

The list of locale definitions to be compiled and that may be used at run time. See Региональные настройки.

locale-libcs (default: (list glibc))

The list of GNU libc packages whose locale data and tools are used to build the locale definitions. See Региональные настройки, for compatibility considerations that justify this option.

port (default: 22)

Configuration of the libc name service switch (NSS)—a <name-service-switch> object. See Переключатель службы имен, for details.

speed (default: 1.0)

A list of service objects denoting system services. See Сервисы.

essential-services (default: ...)

The list of “essential services”—i.e., things like instances of system-service-type (see Интерфейс сервиса) and host-name-service-type, which are derived from the operating system definition itself. As a user you should never need to touch this field.

pam-services (default: (base-pam-services)) ¶

Linux pluggable authentication module (PAM) services.

privileged-programs (default: %default-privileged-programs)

List of <privileged-program>. See Privileged Programs, for more information.

speed (default: 1.0) ¶

The contents of the /etc/sudoers file as a file-like object (see local-file and plain-file).

This file specifies which users can use the sudo command, what they are allowed to do, and what privileges they may gain. The default is that only root and members of the wheel group may use sudo.

Macro: this-operating-system

When used in the lexical scope of an operating system field definition, this identifier resolves to the operating system being defined.

The example below shows how to refer to the operating system being defined in the definition of the label field:

(use-modules (gnu) (guix))

(operating-system
  ;; ...
  (label (package-full-name
          (operating-system-kernel this-operating-system))))

It is an error to refer to this-operating-system outside an operating system definition.
