<translate>This page covers the Funtoo Linux profile system -- how it works, what profiles are available, and how to use [[#Using epro|{{c|epro}}]] to set and change profile settings.
 +
 +
== Profile Types == <!--T:1-->
  
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.
+
<!--T:2-->
 +
Historically, users have had to add a large number of settings to [[Make.conf|{{c|/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 {{c|/etc/make.conf}} into the profile system. The following profile types are available in Funtoo Linux:

{{2Col|{{c|build}}|Defines whether your system is a {{c|current}}, {{c|stable}} or {{c|experimental}} build. {{c|current}} systems will have newer packages unmasked than {{c|stable}} systems. This is defined when your stage is built and is typically not changed.}}

Historically, users have had to add a ton of settings to <code>/etc/[[make.conf]]</code> to customize their Gentoo or Funtoo Linux system, which made setup of the operating system more difficult than it should be.

{{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, {{c|X}} is inherited by {{c|gnome}}. The {{c|epro}} tool will show both as being enabled so there are no surprises.}}

* '''build''' - one 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.

* '''flavor''' - one 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'

=== Origins and Benefits ===
 
  
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:
+
=== ##g##All inherited flavors from desktop flavor##!g##: ===
  
* Fewer settings in <code>/etc/make.conf</code>. <code>CHOST</code> and <code>ARCH</code> no longer set in <code>/etc/make.conf</code>.
+
                    ##c##workstation##!c## (from desktop flavor)
* Separation of concerns -- arch, build, and flavor-related settings are organized together.
+
                            ##c##core##!c## (from workstation flavor)
* User flexibility - any number of mix-ins can be enabled to tweak masks or USE settings as needed.
+
                        ##c##minimal##!c## (from core flavor)

Enabled profiles will be highlighted in cyan. Directly enabled profiles will be in bold and have an asterisk {{c|*}} appended. Sub-profiles enabled via inheritance will be highlighted.
  
=== Using eselect ===

==== Usage Examples ==== <!--T:8-->
The preferred method of adding and removing profiles is to use [[eselect|eselect profile]]. This will ensure that profiles are added correctly and in the proper order. The order is imperative for things to work right.

<!--T:12-->
In most cases you will want to set your "flavor" first. Remember that you can only set ''one'' flavor at time.
+
{{TableStart}}
 +
{{2ColHead|Flavor|Description}}
 +
<tr><td>{{c|minimal}}</td><td>This contains the bare minimum settings for all Funtoo Linux flavors.</td></tr>
 +
<tr><td>{{c|core}}</td><td>The core flavor includes the minimal flavor, plus reasonable settings, and is used for the [[Funtoo_Linux_Installation#Installing_the_Stage_3_tarball|official stage3 downloads]].</td></tr>
 +
<tr><td>{{c|server}}</td><td>In 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.</td></tr>
 +
<tr><td>{{c|workstation}}</td><td>The workstation flavor is a minimal desktop system. It includes the core flavor, plus these mix-ins: {{c|X}}, {{c|audio}}, {{c|dvd}}, {{c|media}} and {{c|console-extras}}.</td></tr>
 +
<tr><td>{{c|desktop}}</td><td>The desktop flavor includes the common settings for any full-featured desktop system. It includes the {{c|workstation}} flavor plus {{c|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.</td></tr>

=== Media Device Mix-ins === <!--T:16-->

###i## eselect profile add 15 16

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 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:

=== How to Use Media Mix-Ins === <!--T:22-->
  
No magic here, whatever you add gets put into the <code>/etc/portage/make.profile/parent</code> file by portage.
+
<!--T:23-->
 +
Our existing {{c|media}} mix-in still exists, and is still pulled in by the {{c|desktop}} and {{c|workstation}} flavors automatically. It now includes the following parent mix-ins:
  
In our case, this file contains:
+
<!--T:24-->
<console>
+
* {{c|mediadevice-audio-consumer}}
###i## cat /etc/portage/make.profile/parent
+
* {{c|mediadevice-video-consumer}}
gentoo:funtoo/1.0/linux-gnu/arch/x86-64bit
+
* {{c|mediaformat-audio-common}}

* {{c|mediaformat-gfx-common}}
gentoo:funtoo/1.0/linux-gnu/flavor/desktop
+
* {{c|mediaformat-video-common}}
gentoo:funtoo/1.0/linux-gnu/mix-ins/kde
+
</console>
+
{{fancywarning|Please, do not add anything manually into <code>parent</code> file. This may result in profile breakage.}}
+
  
== For Developers ==
+
<!--T:25-->
 +
In addition, there is a new {{c|media-pro}} mix-in which needs to be enabled manually, which pulls in the following mix-ins:

So far in Funtoo we have used the exact same profiles as Gentoo thus Funtoo/2008.0 was strictly the same thing as Gentoo/2008.0 or the barely the same 10.0. This (monolithic) profile was set though a symbolic link named <code>/etc/make.profile</code> pointing on a complex directory architecture located somewhere under <code>/usr/portage/profiles</code>. This is no longer valid with the Funtoo 1.0 profiles as they are split in several smaller bricks which are then glued together via the  <code>/etc/portage/make.profile/parent</code> file (You do not need to include everything, just use the "bricks" you need). Those bricks belongs to several categories:

So typically, you would enable the {{c|desktop}} or {{c|workstation}} flavor, and if you need professional hardware support, you'd also enable the {{c|media-pro}} mix-in. If you needed any additional media formats support, you could enable one or more of the {{c|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.
  
# MANDATORY -- An "arch" profile which defines settings for a particular architecture. You'll want to set this to whatever arch your system is and leave it alone. '''Setting it to a different arch than your system could severely break it.'''

# MANDATORY -- A "build" profile which should match the tree you wish to use. '''Stable''', '''Current''' (~arch), or '''Experimental''' (use it if you are brave enough and find '''current''' too stable).
+
# MANDATORY -- A "flavor" profile (what was previously known as ''profiles'' is still known as such in Gentoo) which describes the kind of system you want:
+
#* minimal - Be warned, minimal is exactly what it says, the minimal profile stuff you need for a usable system, nothing else. This is really for people who know what they're doing.
+
#* core - This is the core profile. This is for stuff that affects both desktops and servers.
+
#* desktop - Exactly what it says. If you're using a desktop, you should set this as your flavor.
+
#* server - If you're running a server, you should set this as your flavor.
+
# OPTIONAL -- One or more "mix-ins" profiles which describe optional add-ons. 'mix-ins' are the heart of the Funtoo 1.0 profiles. Unlike the monolithic profiles which sets a massive amount of use flags and options for you, we've split them into logical add-on profiles. For instance if you want support for gnome, you would add the gnome mix-in to your current profiles. That mix-in sets all the proper use flags and such for gnome. Same with others. Want dvd support? Add that one in. Using a rhel5 kernel which requires special versions of packages such as udev? There's a mix-in for that too. Run a mail server? web server? There's mix-ins for those also. Expect this category to grow in the future as new mix-ins are created.

Funtoo Linux stores its profile settings in the {{f|/etc/portage/make.profile/parent}} file.

A simple server might have profile settings as follows:

This page covers the Funtoo Linux profile system -- how it works, what profiles are available, and how to use epro to set and change profile settings.

Profile Types

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.

Using epro

epro show will display the current profile settings on your system:

#  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:

#  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.

Usage Examples

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

Flavors

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

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.

Mix-ins

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

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.

Media Device Mix-ins

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.

Media Format Mix-ins

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.

How to Use Media Mix-Ins

Our existing media mix-in still exists, and is still pulled in by the desktop and workstation flavors automatically. It now includes the following parent mix-ins:

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

In addition, there is a new media-pro mix-in which needs to be enabled manually, which pulls in the following mix-ins:

  • 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.

How Profile Settings are Stored

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

History and Origins

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:
