Last Boss of Linux

What is Gentoo Linux?
Gentoo is a free operating system based on Linux that can be automatically optimized and customized for just about any application or need.
Extreme configurability, performance, and a top-notch user and developer community are all hallmarks of the Gentoo experience.
Of course, Gentoo is more than just software. It is also a community around the distribution. Gentoo benefits from around 250 developers and thousands of users, many of which are experts in their fields. The distribution project provides the means for the users to enjoy Gentoo: documentation, infrastructure, release engineering, software porting, quality assurance, security followup, hardening, and more.

The philosophy of Gentoo
The goal of Gentoo is to strive to create near-ideal tools. Tools that can accommodate the needs of many different users all with divergent goals. Don’t you love it when you find a tool that does exactly what you want to do? Doesn’t it feel great? Our mission is to give that sensation to as many people as possible.

Gentoo is all about choices.
First of all, welcome to Gentoo! You are about to enter the world of choices and performance. Gentoo is all about choices. When installing Gentoo, this is made clear several times — users can choose how much they want to compile themselves, how to install Gentoo, what system logger to use, etc. Gentoo is a fast, modern meta-distribution with a clean and flexible design. It is built on an ecosystem of free software and does not hide what is beneath the hood from its users.

Gentoo vs binary-based distributions

Benefits of compiling on your own machine
Speed
up to 50-60%
(2% in common)
Cutting-edge packages & kernels
Customization of individual software packages

Open Source and why it’s more Secure
Due to the flexibility inherent in Gentoo's Portage tool and USE flags, Gentoo encourages users to build software with only the features they need. This decreases code size and complexity, and tends to increase security.

IKEA Effect
IKEA Effect — is a cognitive bias in which consumers place a disproportionately high value on products they partially created.

Disadvantages of Gentoo Linux
You have to build the entire system from scratch.
There’s a much smaller community, and although the Gentoo Wiki is great, sometimes that’s not enough
You essentially have to compile every program from source, it’s going to take forever.
Experience required
Not for casual users
The average to install it is 2 to 6 hours. Some require more than 10 hours, there are also those who require 2 to 7 days.

A wise Gentoo user once said: all problems are caused by the user - he was wrong
There is a very high probability that the system will not work with other hardware
Gentoo allows users to easily patch almost any source-based package. But this still will not save you from frequent recompilation of system components

Where is Gentoo Linux used?
12+ active Distributions based on Gentoo.
A large number of corporations use open source software developed by Gentoo for their own projects. For example Google with Chromium OS.
People concerned about their security are actively using various distributions based on Gentoo. For example Liberté Linux
Kaspersky Rescue Disk is based on Gentoo Linux

Gentoo is the final boss of Linux(almost)
And as we know, the game gives the most experience for defeating the boss.
