ego (aka personality) is master program used to manipulate Funtoo system settings. It is present in base system, and in every stage3. It consist of various modules, which serve for view, change and control a basic system. Below we describe ego's module called epro which, one may guess, is a profile manager.

Usage

Funtoo profiles are used to define defaults for Portage specific to your needs. There are five basic profile types: arch, build, subarch, flavor, and mix-ins:

arch
typically 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.
build
defines 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.
subarch
Defines optimizations for your CPU. 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.
flavor
defines the general type of system, such as server or desktop, and will set default USE flags appropriate for your needs.
mix-ins
define various optional settings that you may be interested in enabling.

One arch, build and flavor must be set for each Funtoo Linux system, while mix-ins are optional and you can enable more than one if desired.

Remember that profiles can often be inherited. For example, the desktop flavor inherits the workstation flavor settings, which in turn inherits the X and audio mix-ins. You can view this by using epro:

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 available profiles:

root #  epro list

Enabled profiles will be highlighted in cyan. Directly enabled profiles will be in bold and have an asterisc * appended.

To change the profile arch to x86-64:

root # epro arch x86-64bit

To change the build to current:

root # epro build current

To change the subarch to generic_64:

root # epro subarch generic_64

To change the profile flavor:

root #  epro flavor desktop

To add a mix-in:

root #  epro mix-ins +gnome

To remove a mix-in:

root #  epro mix-ins -gnome

To get a JSON output of your profiles:

root #  epro show-json

To get the current value of a given profile:

root #  epro get <build
