Gentoo Prefix with llvm
introduction For me, Gentoo Prefix is one of the most interesting open-source projects. It helps me install a complete Gentoo-system under random folder (as long as you can write to it) on many OSes (macOS, Linux, Solaris) and many archtechtures (arm64, x86_64, etc.). The system is managed by portage, so I can leverage the already-existing gentoo repository and even enpower it with overlays to form a unique system.1
To bootstrap prefix easily, currently you need bootstrap-prefix.
