The system set, also referred to as @system in Portage development, contains the software packages required for a standard Gentoo Linux installation to run properly.
emerge --pretend @system
The system packages are defined by the Gentoo profiles (through the packages files)
An end-user can easily see which packages are seen as part of the system set by running the following emerge command:
firefox="$(qlist -I | xargs qlop -t | grep firefox | awk '{print $2}')"; echo $firefox / 60 | bc
eix --print-all-useflags|grep -o "\-.*" | grep -v _ | grep -v +
