Gentoo Linux

Introduction on Gentoo's official website:

Gentoo Linux is a set of generic, fast, and completely free Linux distributions, designed for developers and network professionals. Unlike other releases, Gentoo Linux has an advanced package management system called Portage. In the traditional BSD ports, Portage is a real automatic import system. However, Portage in Gentoo is written in Python and has many advanced features, this includes file dependencies, fine-grained package management, OpenBSD-style virtual installation, secure uninstallation, system framework files, virtual software packages, and configuration file management.

Gentoo Linux is a special Linux release that can be automatically optimized and customized for any application and needs. Gentoo has excellent performance, high configuration, and top-notch users and development communities.

Special installation methods

• A large number of terminals are used during the installation process

• You can use iso of other releases to simplify installation.

• If an available Linux system already exists on the machine and you do not need to download the iso image file, you only need to download a stage3 tarball of less than MB and A portage snapshot of less than 60 MB for installation.

• Allows your geeks to ssh to your machine for installation.

Special Release Methods

• Rolling update

Gentoo Linux usesRolling updateTo release the new version. As long as you update the system software package, you can use the latest system. All of this is smooth. Currently, only Gentoo, Arch, and LMDE are available for Rolling updates. However, Gentoo is the most stable one. When other Linux releases are released, enthusiasts will be busy installing the latest version.

Special Package Manager

• Thanks to the advanced features of portage, you can customize software compilation options and control software dependencies.

• Stable branch and unstable BranchSecurity mix.

• The slot killer feature allows you to install different versions of the same software, andSecure coexistence. For example, there are python2.7 and python3.3 on gentoo. You can also install gcc of different versions to coexist with the system.

Special philosophical Philosophy

Make your own choiceFrom the very beginning, you will face various choices, and gentoo gives you the maximum freedom.

• Does the hard disk partition adopt GPT or MBR? How to organize the root directory? Which ones need to be mounted separately? What does the file system choose? Even fine-grained mounting options.

• Choose gentoo as the server or desktop system? Do you need X-window? Is a DE or WM installed?

• Does init system choose the default openrc or the aggressive EMD?

• Can I access the Internet through PPPoE or dhcp? Is there a wireless network card?

• Which kernel is installed? Gentoo has many kernel types with different patches for you to choose from.

You need to make decisions on your own. There is no best choice but the best choice for you. This is also gentoo's philosophy.
