--USE-flags
A man, his /etc/portage, and 400 lines of personality.
A USE flag is how a Gentoo user tells the computer who they are. -gnome +kde
is not a build option; it is a worldview. +hardened -systemd is not a
preference; it is a hill, and they will die on it, slowly, during a four-hour
emerge.
Sample make.conf personality test
USE="-* minimal"— wants you to know they suffer.USE="X gtk qt5 kde gnome"— has never finished an install.CFLAGS="-O3 -march=native -funroll-loops -fomg-fast"— that last flag isn't real, and they have it set anyway.
The binary-distro user types apt install firefox and is browsing the web
ninety seconds later. The ricer would never. The ricer has standards.
