"Self-hosting GNU/Linux distributions are one of our major
interests here since we will be exploring that field as thoroughly
as possible. They provide the entire building system for creating a
GNU/Linux based platform on most architectures, tailored to suit
particular needs. Among them we have various implementations of the
same idea like Gentoo, T2, CLFS. The reason for it has little to do
with 'optimize your binaries for your cpu' scenario, which for
various reasons may not always be the best way to go. Thing is,
that within the GNU/Linux distribution world, such projects allow
end users to tap into a much bigger control power over their
platform. Over its structural coherence, over its features and
hidden gems. And that is the way such projects should be seen.
"Among these projects, there is also a varying degree in
automation oriented towards providing the target system. Gentoo's
Portage Package Management system can be seen as a heavily BSD
ports-influenced system for building and deploying packages..."
