Bu sayfa Funtoo Linux profil sisteminin nasıl çalıştığı, hangi profillerin mevcut olduğu ve
epro'nun profil ayarlarını seçme ve değiştirmede nasıl kullanılacağını içermektedir.
Kullanıcıların Gentoo yada Funtoo Linux sistemlerini kişiselleştirebilmeleri için çok sayıda ayarı
/etc/make.conf dosyasına girmesi gerekiyordu, ki bu da işletim sisteminin kurulumunu olması gerektiğinden daha fazla zorlaştırıyordu. Gentoo Linux'te sadece tek bir "sistem profili" tanımlanmasına olanak sağlıyor. Sistem profilini Portage'ın sisteminizde bulunan herşeyi inşa etmesinde kullandığı varsayılan ayarlar olarak düşünebilirsiniz. Funtoo Linux tek bir profilden ziyade bir çok alt profil kullanır ve
/etc/make.conf'ta tanımlanan bir çok ayarı profil sistemine entegre eder. Funtoo Linux'te aşağıda var olan profil tipleri bulunmaktadır:
|Alt Profil Tipi||Tanım|

Flavors ve mix-ins kendi kategorilerinden ayar devralabilirler. Örnek vermek gerekirse

epro bu durumda iki seçeneğide etkin olarak gösterecektir.
The purpose of this new system is to:
- Help developers to organize and curate optimal settings for the community. We use these settings, such as our
gnomemix-in, to build official GNOME stages. So we want them to work, and work well.
- Allow our users to use the
eprotool (also known as its long form:
ego profileto manage
USEsettings in bulk. We want our mix-ins to be useful for enabling a logical set of
USEflags by name, such as
mediaformat-audio-extrarather than listing a long list of
Really, we consider the selection and maintenance of optimal
USE settings to be a community task, rather than an individual task. This is a fundamental cultural difference of Funtoo as compared to Gentoo.
See the Wolf Pack Philosophy for more information on these cultural differences which have a practical impact on how we do our work.

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.

A system can have only one flavor profile enabled at a time. The following flavors are available:
|This contains the bare minimum settings for all Funtoo Linux flavors.|

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|
|Common, universally-supported media devices, like IEEE-1394 (Firewire), CDDA, CDIO. Other mediadevice mix-ins have this as a parent.|
|Consumer audio devices, such as personal portable media players (iOS, iPod, etc.)|
|Pro audio support, such as JACK.|
|Consumer video support, such as DVD, Blu Ray, V4L|
|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|
|Common (ie. popular) video formats.|
|More esoteric video formats.|
|Common (ie. popular) audio formats.|
|More esoteric audio formats.|
|Common (ie. popular) graphics formats.|
|More esoteric graphics formats.|
How to Use Media Mix-Ins
media mix-in still exists, and is still pulled in by the
workstation flavors automatically. It now includes the following parent mix-ins:
In addition, there is a new
media-pro mix-in which needs to be enabled manually, which pulls in the following mix-ins:
So typically, you would enable the
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
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:
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:
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
ARCHno longer set in
- 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.
