Данная страница содержит сведения о системе профилей Funtoo Linux -- о том, как они они работают, какие имеются профили и как использовать epro для первоначальной установки или изменения настроек профилей.

Типы профилей

Historically, users have had to add a large number of settings to /etc/make.conf to customize their Gentoo or Funtoo Linux system, which made setup of the operating system more difficult than it should be. In Gentoo Linux, it is possible to only define one system profile. Think of a system profile as the default settings that Portage uses for building everything on your system. Rather than a single profile, Funtoo Linux uses multiple sub-profiles, and moves many types of settings that are normally stored in /etc/make.conf into the profile system. The following profile types are available in Funtoo Linux:

Sub-Profile TypeDescription
archTypically x86-32bit or x86-64bit, this defines the processor type and support of your system. This is defined when your stage was built and should not be changed.
buildDefines whether your system is a current, stable or experimental build. current systems will have newer packages unmasked than stable systems. This is defined when your stage is built and is typically not changed.
subarchDefines CPU optimizations for your system. The subarch is set at the time the stage3 is built, but can be changed later to better settings if necessary. Be sure to pick a setting that is compatible with your CPU.
flavorDefines the general type of system, such as server or desktop, and will set default USE flags appropriate for your needs.
mix-insDefines various optional settings that you may be interested in enabling.
   Note

Flavors can (and often do) inherit settings from other flavors and mix-ins. Mix-ins can also inherit settings from other mix-ins. For example, X is inherited by gnome. The epro tool will show both as being enabled so there are no surprises.

Использование epro

epro show отображает текущие настройки профилей в вашей системе:

root #  epro show

=== Enabled Profiles: ===

        arch:  x86-64bit
       build:  current
     subarch:  intel64-haswell
      flavor:  desktop
     mix-ins:  gnome


=== All inherited flavors from desktop flavor: ===

                     workstation (from desktop flavor)
                            core (from workstation flavor)
                         minimal (from core flavor)

=== All inherited mix-ins from desktop flavor: ===

                               X (from workstation flavor)
                           audio (from workstation flavor)
                             dvd (from workstation flavor)
                           media (from workstation flavor)
      mediadevice-audio-consumer (from media mix-in)
                mediadevice-base (from mediadevice-audio-consumer mix-in)
      mediadevice-video-consumer (from media mix-in)
                mediadevice-base (from mediadevice-video-consumer mix-in)
        mediaformat-audio-common (from media mix-in)
          mediaformat-gfx-common (from media mix-in)
        mediaformat-video-common (from media mix-in)
                  console-extras (from workstation flavor)
                           print (from desktop flavor)

To view all available sub-profile settings, use epro list:

root #  epro list

Enabled profiles will be highlighted in cyan. Directly enabled profiles will be in bold and have an asterisk * appended. Sub-profiles enabled via inheritance will be highlighted.

Примеры использования

Add the mix-ins gnome and kde
root #  epro mix-ins +gnome +kde
Remove a mix-in, for example gnome
root #  epro mix-ins -gnome
Change the profile arch to x86-64bit
root #  epro arch x86-64bit
Change the subarch to generic_64
root #  epro subarch generic_64
Change the system flavor
root #  epro flavor desktop
Get JSON output of profile settings
root #  epro show-json
Get current sub-profile setting in text form
root #  epro get [profiletype]

Конфигурации

В системе можно одновременно задействовать только один профиль конфигурации. Доступны следующие варианты:

FlavorDescription
minimalThis contains the bare minimum settings for all Funtoo Linux flavors.
coreThe core flavor includes the minimal flavor, plus reasonable settings, and is used for the official stage3 downloads.
serverIn the future, the server flavor will include the core flavor, plus specific settings designed for servers. At the moment, it is equivalent to the core flavor.
workstationThe workstation flavor is a minimal desktop system. It includes the core flavor, plus these mix-ins: X, audio, dvd, media and console-extras.
desktopThe desktop flavor includes the common settings for any full-featured desktop system. It includes the workstation flavor plus printing support. The user is expected to further customize their system with a desktop environment of choice, such as KDE, GNOME, or XFCE, possibly by using a mix-in.

Дополнения

Одновременно в системе может быть задействовано любое количество дополнений. Доступные следующие варианты дополнений:

Mix-inDescription
audioEnables core audio-related settings, currently related to ALSA.
console-extrasEnables things that are nice to have for console-only systems. Currently enabling gpm in USE.
dvdUSE settings related to optical drives -- CDR/DVD-ROM/RW use.
gnomeUSE and package.use settings required to merge GNOME. Designed to be used with desktop or workstation flavor.
hardenedEnables hardened support.
kdeUSE and package.use settings required to merge KDE. Designed to be used with desktop or workstation flavor.
mediaUSE settings related to audio/video media encoding. Can be for desktops or servers.
printEnables printing capability.
vmware-guestSettings related to using Funtoo Linux as a VMWare virtual machine guest.
XSettings related to the X Window System and hardware support.
xfceUSE settings required for merging XFCE.

Дополнения для мультимедийных устройств

Media device mix-ins have been created to support media devices, including external and portable devices, and associated low-level hardware support and hardware-focused codecs. Media devices have been categorized into audio and video categories, and consumer and professional categories. "Consumer" devices are those devices that regular desktop users might typically use, while "professional" devices are those that professionals, hobbyists or enthusiasts would typically use. Here are the new mix-ins for media devices:

Media Device Mix-inDescription
mediadevice-baseCommon, universally-supported media devices, like IEEE-1394 (Firewire), CDDA, CDIO. Other mediadevice mix-ins have this as a parent.
mediadevice-audio-consumerConsumer audio devices, such as personal portable media players (iOS, iPod, etc.)
mediadevice-audio-proPro audio support, such as JACK.
mediadevice-video-consumerConsumer video support, such as DVD, Blu Ray, V4L
mediadevice-video-proPro video support, such as dv, dc1394.

Дополнения для медиа-форматов

Media format mix-ins have been created to support media formats for reading, writing, encoding and decoding images, audio and video. They have been organized into a "common" collection, for popular formats, and an "extra" collection, which is intended to include "everything else". Let's look at the new mix-ins:

Media Format Mix-inDescription
mediaformat-video-commonCommon (ie. popular) video formats.
mediaformat-video-extraMore esoteric video formats.
mediaformat-audio-commonCommon (ie. popular) audio formats.
mediaformat-audio-extraMore esoteric audio formats.
mediaformat-gfx-commonCommon (ie. popular) graphics formats.
mediaformat-gfx-extraMore esoteric graphics formats.

Использование медиа-дополнений

Существующее дополнение media никуда не делось и по прежнему автоматически подтягивается конфигурациями desktop и workstation. В настоящее время это дополнение включает следующие родительские дополнения:

  • mediadevice-audio-consumer * mediadevice-video-consumer * mediaformat-audio-common * mediaformat-gfx-common * mediaformat-video-common

В дополнение к этому, теперь еще есть новое дополнение media-pro, которое устанавливается вручную. Оно подключает следующие дополнения:

  • mediadevice-audio-pro
  • mediadevice-video-pro

So typically, you would enable the desktop or workstation flavor, and if you need professional hardware support, you'd also enable the media-pro mix-in. If you needed any additional media formats support, you could enable one or more of the mediaformat-*-extra mix-ins to add the formats you needed. Of course, it's possible to enable only the specific mix-ins you need, and also complement these mix-ins with specific USE variable settings you might require.

Где хранятся настройки профиля

Funtoo Linux stores its profile settings in the /etc/portage/make.profile/parent file. Typically, users don't need to modify this file, instead using ego and epro to make changes, but it can be handy to take a look at what the contents of the file look like. A simple server might have profile settings as follows:

   /etc/portage/make.profile/parent
gentoo:funtoo/1.0/linux-gnu/arch/x86-64bit
gentoo:funtoo/1.0/linux-gnu/build/current
gentoo:funtoo/1.0/linux-gnu/flavor/core

Настройки профиля для типичного настольного компьютера могут выглядеть следующим образом:

   /etc/portage/make.profile/parent
gentoo:funtoo/1.0/linux-gnu/arch/x86-64bit
gentoo:funtoo/1.0/linux-gnu/build/current
gentoo:funtoo/1.0/linux-gnu/flavor/desktop
gentoo:funtoo/1.0/linux-gnu/mix-ins/dvd
gentoo:funtoo/1.0/linux-gnu/mix-ins/media

История

This new system is really a completion of the original cascading profile design that was co-designed by Daniel Robbins and Seemant Kulleen and implemented by Seemant Kulleen as part of Portage. Funtoo Profiles designed to leverage the existing cascading profile system and provide something much more useable and maintainable for users and developers alike. Here are some of its benefits:

  • Fewer settings in /etc/make.conf. CHOST and ARCH no longer set in /etc/make.conf.
  • Separation of concerns -- arch, build, and flavor-related settings are organized together.
  • User flexibility - any number of mix-ins can be enabled to tweak masks or USE settings as needed.
