What is a profile?

In Gentoo and Funtoo Linux, profiles are used to define base system settings, and have historically had a lot of untapped potential. In Funtoo Linux, I wanted to take advantage of some of this potential to allow Funtoo Linux users to easily tailor their system for various types of roles. Enter the new Funtoo profile system.

Profile Types

Historically, users have had to add a ton 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. Funtoo Linux uses multiple profiles per system. The following profile types are available in Funtoo Linux:

archOne arch profile is enabled, at build time, and is not changed. This defines CPU architecture-specific settings.
subarchOne subarch profile is typically enabled at build time, and defines the CPU optimizations in use.
buildOne build profile is enabled, at build time, and is generally not changed. It defines the type of build, such as current or stable, and associated settings.
flavorOne flavor is enabled per system, and can be changed by the user. This defines the general use of the system, such as minimal, core, workstation or desktop
mix-insZero or more mix-ins can be enabled that enable settings specific to a particular subset of features, such as gnome, kde, media, mate, X, hardened.

Flavors

A system can have only one flavor profile enabled at a time. The following flavors are available:

minimalThis flavor defines the most minimal possible flavor. It currently only contains defaults for all Funtoo Linux flavors.
coreThe core flavor is the minimal flavor plus reasonable USE options, and is used for stage3 builds.
serverThe server flavor is intended for servers but at this time just tracks core.
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 is a full-featured desktop system, minus desktop environment (add KDE, GNOME or XFCE as a mix-in.) It includes the workstation flavor plus printing support.

Mix-ins

A system can have any number of mix-ins enabled at a time. The following mix-ins are available:

{{2Col|gnome|USE and package.use settings required to merge GNOME. Designed to be used with desktop or workstation flavor.

{{2Col|kde|USE and package.use settings required to merge KDE. Designed to be used with desktop or workstation flavor.

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.
hardenedEnables hardened support.
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.

Setting Profiles

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

Profile settings for a desktop might look like this:

   /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

Using ego / epro

epro is a new personality tool designed to eventually replace eselect profile. If your desired subarch is not listed with "eselect profile list", try using "epro list".

For more information, see this news: News: Better Experiences: Ego and Vim

And the ego wiki page itself: Package:Ego

   Important

This section is in need of updates.


Using epro

The preferred method of adding and removing profiles is to use epro. This will ensure that profiles are added correctly and in the proper order. The order is imperative for things to work right.

Type the following to view a list of available options for epro: For a start, let's see what the default configuration has to offer. Get an overview using the list command:

root # epro list
=== arch: ===

    arm-32bit, (pure64*), x86-32bit, x86-64bit

=== subarch: ===

    amd64-bulldozer-pure64, amd64-jaguar-pure64, amd64-k10-pure64
    amd64-k8+sse3-pure64, amd64-k8-pure64, amd64-piledriver-pure64
    amd64-steamroller-pure64, atom_64-pure64, btver1_64-pure64
    core-avx-i-pure64, core2_64-pure64, corei7-pure64, generic_64-pure64*
    intel64-broadwell-pure64, intel64-haswell-pure64, intel64-ivybridge-pure64
    intel64-nehalem-pure64, intel64-sandybridge-pure64, intel64-silvermont-pure64
    intel64-westmere-pure64, native_64-pure64, nocona-pure64, opteron_64-pure64
    xen-pentium4+sse3_64-pure64

=== build: ===

    (current*), experimental, stable

=== flavor: ===

    core, desktop*, hardened, minimal, server, workstation

=== mix-ins: ===

    X, audio, cinnamon, console-extras, dvd, gnome, hardened, kde
    lxde, lxqt, mate, media, media-pro, mediadevice-audio-consumer
    mediadevice-audio-pro, mediadevice-base, mediadevice-video-consumer
    mediadevice-video-pro, mediaformat-audio-common, mediaformat-audio-extra
    mediaformat-gfx-common, mediaformat-gfx-extra, mediaformat-video-common
    mediaformat-video-extra, no-emul-linux-x86, no-systemd, print
    python3-only, vmware-guest, xfce*

As in several other Funtoo utilities, a star (*) on the right indicates an active item (your case may differ from the example above). Now, let's head over and add some mix-ins. To add, say, the mix-ins gnome and kde we'd have to enter:

root # epro mix-ins +gnome +kde

If we want to remove a mix-in, for example gnome, simply enter:

root # epro mix-ins -gnome

History and Origins

This new system is really a completion of the original cascading profile design that was designed by Daniel Robbins 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.
