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. Funtoo Linux uses multiple sub-profiles per system. The following profile types are available in Funtoo Linux:
Sub-Profile | Description |
---|---|
arch | This defines CPU-specific settings. Only one arch profile is enabled at install time, and cannot be changed. |
subarch | This further refines the CPU-specific settings. One subarch profile is typically enabled at install time. |
build | This defines the type of stability, such as current or stable , and its associated settings. One build profile is enabled, at install time, and is generally not changed. |
flavor | This defines the intended use of Funtoo, such as minimal , core , workstation or desktop . One flavor is enabled, and can be changed by the user. |
mix-ins | These can be enabled by the user, based on the features the user wants, such as gnome , kde , media , mate , X , and hardened . |
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:
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.
Usage Examples
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] |
Flavors
A system can have only one flavor profile enabled at a time. The following flavors are available:
Flavor | Description |
---|---|
minimal | This contains the bare minimum settings for all Funtoo Linux flavors. |
core | The core flavor includes the minimal flavor, plus reasonable settings, and is used for the official stage3 downloads. |
server | 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. |
workstation | The workstation flavor is a minimal desktop system. It includes the core flavor, plus these mix-ins: X , audio , dvd , media and console-extras . |
desktop | The 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-in | Description |
---|---|
audio | Enables core audio-related settings, currently related to ALSA. |
console-extras | Enables things that are nice to have for console-only systems. Currently enabling gpm in USE. |
dvd | USE settings related to optical drives -- CDR/DVD-ROM/RW use. |
gnome | USE and package.use settings required to merge GNOME. Designed to be used with desktop or workstation flavor. |
hardened | Enables hardened support. |
kde | USE and package.use settings required to merge KDE. Designed to be used with desktop or workstation flavor. |
media | USE settings related to audio/video media encoding. Can be for desktops or servers. |
print | Enables printing capability. |
vmware-guest | Settings related to using Funtoo Linux as a VMWare virtual machine guest. |
X | Settings related to the X Window System and hardware support. |
xfce | USE 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-in | Description |
---|---|
mediadevice-base | Common, universally-supported media devices, like IEEE-1394 (Firewire), CDDA, CDIO. Other mediadevice mix-ins have this as a parent. |
mediadevice-audio-consumer | Consumer audio devices, such as personal portable media players (iOS, iPod, etc.) |
mediadevice-audio-pro | Pro audio support, such as JACK. |
mediadevice-video-consumer | Consumer video support, such as DVD, Blu Ray, V4L |
mediadevice-video-pro | Pro 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-in | Description |
---|---|
mediaformat-video-common | Common (ie. popular) video formats. |
mediaformat-video-extra | More esoteric video formats. |
mediaformat-audio-common | Common (ie. popular) audio formats. |
mediaformat-audio-extra | More esoteric audio formats. |
mediaformat-gfx-common | Common (ie. popular) graphics formats. |
mediaformat-gfx-extra | More 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:
- Fewer settings in
/etc/make.conf
.CHOST
andARCH
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.
See Custom Profiles for information on how to extend the profile system.
