FEATURES

The FEATURES variable contains a list of Portage features that the user wants enabled on the system, effectively influencing Portage's behavior. It is set by default via /usr/share/portage/config/make.globals, but can be easily updated through /etc/portage/make.conf. Since this is an incremental variable, FEATURES values can be added without directly overriding the ones implemented through the Gentoo profile.

FEATURES is often prepended to the emerge command for e.g. keeping the build log or triggering tests:

root #FEATURES="keeptemp test" emerge -1a foobar
