Linux Distributions

Linux distributions are software packages that include the system kernel and a large set of different applications and software for installing the OS.

You may have heard of big Linux companies like RedHat (RHEL /CentOS /Fedora distributions), Canonical (Ubuntu distribution), or SUSE (SUSE Linux Enterprise Server /openSUSE distributions). There are thousands of other small companies and organizations that also create their own Linux distributions, you can find them on the DistroWatch website news and information about all Linux distributions, as well as their rating.

When choosing a Linux distribution, you will always encounter the fact that some distribution X will have a wider set of different options and features than distribution Y. However, in some cases, Distribution Y may meet your specific needs more than distribution X. The choice is yours. Since most Linux distributions are free, you can try different distributions until you find exactly the one that suits you best. This article is designed to help you make a choice.

Features of distributions

Although all Linux distributions are based on the Linux kernel, each of them has a set of basic distinguishing features that characterize a particular distribution:

  • Architecture is the type of processor that the distribution supports.
  • An initialization system is a fundamental approach to starting and managing processes.
  • Package Manager is the default distribution package management tool.
  • A desktop environment is the graphical user interface of the distribution.

Now we will look at all this in detail.

Architecture

Architecture is the type of processor that the distribution supports. The most common processor architectures include:

  • x86 (or i586/i686) is a 32 is bit processor compatible with Intel and AMD.
  • x86_64 is a 64-bit processor compatible with Intel and AMD.
  • ARM processor architecture optimized for use on mobile devices (tablets, smartphones).
  • PowerPC is an outdated processor architecture that was once used in Apple computers.

Initialization system

The initialization system is the very first process (daemon) that starts when a computer starts up with a Linux kernel-based OS and functions for the entire duration of the system’s operation; it is the parent process of each subsequent process that runs on the device.

The question of choosing an initialization system is hotly contested: there are both supporters/opponents of the SysV initialization system and supporters/opponents of the systemd system. And given that this software determines how the system will manage processes, the choice becomes not as simple and trivial as it may seem at first glance.

  • SysV is a traditional initialization system that has its roots in Unix System V. It is considered more stable, but perhaps less functional, than systemd.
  • systems is a more modern initialization system. It works faster than SysV, and also allows you not only to start processes once at boot but also allows you to monitor them (whether the process started, whether the process” crashed”, etc.).

NoteYou may also encounter other initialization systems, but SysV and systemd are the undisputed leaders among them. If you don’t consider yourself an experienced user, then it doesn’t matter which initialization system you choose. Most modern distributions have begun to rely on systemd, so distributions with SysV (or alternative versions of it) are becoming less and less common at the moment.

Package Manager

Package Manager (or “package manager”)) is the default distribution package management tool.

On Linux, all software is delivered as packages. The work of archiving and managing these packages is performed by package managers. Most packages are interchangeable, although utilities such as alien can perform the conversion between some types of packages.

Different distributions have different package managers:

  • dpkg manages Debian-oriented packages (.deb) distributed in Debian-based Linux distributions, including Ubuntu and Linux Mint, using the apt tool. apt (short for “advanced packaging tool”).
  • RPM Package Manager installs / manages packages in the .rpm format. It uses tools such as dnf, yum, and zypper.
  • flatpak is a cross-platform sandbox/container format.
  • pacman is a package manager for Arch Linux and its derived distributions.
  • portage developed for Gentoo Linux, and now also used by ChromeOS and several other distributions.
  • snap is an Ubuntu-specific form of container application deployment.
  • eopkg is used in the Solus distribution.

Note: Although you can choose a specific package management tool, the package type is tightly bound to the specific distribution. This way, you will never see a version of Ubuntu that uses. rpm packages. Different distributions operate different software repositories. Some programs created by independent developers can only appear in one or two package formats. If your priority is to have broad access to open source software, then a distribution that uses packages in the .deb format or .rpm is likely to be the best choice.

Desktop environment

When it comes to the main differences between Linux distributions, people for some reason believe that it all comes down to differences in the desktop environment used. The irony is that most distributions support the installation of a wide variety of desktop options.

The best desktop options strike a balance between their degree of configurability and relative resource consumption. A completely new computer or a high-performance computer can work with any version of the desktop environment. But on weaker or older hardware (especially netbooks), choosing a resource-intensive desktop option can negatively affect the use of the entire system.

Modern desktops tend to be less customizable, they focus on aesthetic design and appearance.

Configuration of desktop environments:

  • More customizable desktops include Xfce, LDXE, Cinnamon, MATE, and KDE.
  • Less customizable desktops include DDE (Deepin), GNOME 3, and Pantheon.

What remains unchanged

In any distribution, the following basic principles remain unchanged:

  • There is always a Linux kernel. The kernel is the main component of Linux distributions, which Linus Torvalds wrote back in 1991 (now he has thousands of authors!). The kernel is the interface between your computer’s hardware (keyboards, mice, displays, etc.) and its software.
  • Standard GNU software (tools such as bashlsrm, etc.). Most of them are command-line utilities that make up the main (but critical) part of any Linux system. You can think of the kernel as a bus that runs between your computer’s hardware and software, and GNU software as a set of tools that you need to keep the bus on the road!
  • General-purpose software that comes with the Linux distribution. This list usually includes text editors, a web browser, an email client, (possibly) a word processor or office suite, and so on.

Pay or not pay?

Buying Linux can give you advantages that the free versions don’t have, such as:

  • Physical Guides (SUSE Linux Enterprise Server & Red Hat Enterprise Linux is particularly good).
  • Support from distribution vendors for a certain period. Distributors such as Red Hat provide corporations with guarantees of a high level of customer support.
  • Additional commercial software (which is protected by copyright).

Overview of Linux distributions

Some many companies and organizations have created their distributions or varieties of Linux systems that can meet the needs of any user. Probably too many distributions! In our guide, we will try to make this list simpler and shorter by looking only at the most popular distributions.

Debian

Debian is the granddaddy of all Linux distributions, and it has many offshoots, including Ubuntu. The distribution was released in September 1993. Initially, the difference between Debian and Red Hat Linux-based systems was that it had a huge library of software packages (about 50,000 libraries) and it had an automatic software management system called apt.

This meant that instead of having to download many app packages individually, you could just tell Debian which app you needed and it would automatically do the rest for you. The distribution has traditionally been known to lag behind some other distributions in terms of having the most up-to-date packages, but it makes up for this with good stability, since the main packages are well tested.

Note: Choose the name of a character from the Toy Story cartoon as the name of the next Debian release.

Debian

Ubuntu

Ubuntu was released in 2004 by Canonical and quickly became popular. Canonical positioned Ubuntu as a simple Linux distribution with a graphical desktop, which was supposed to replace the use of the command line. This is the most well-known Linux distribution.

Ubuntu is an easy-to-use system for beginners, an offshoot of Debian Linux. It comes with a large number of pre-installed applications and even more of the most diverse software that is located in its repositories. Canonical also offers commercial support for Ubuntu. There are many different builds based on Ubuntu:

  • Edubuntu is a build aimed at educational institutions.
  • Kubuntu or KDE is used as the desktop environment.
  • Lubuntu is a lightweight version of Ubuntu.
  • In addition to the official builds, today there are more than 40 third-party versions in circulation!

Ubuntu is released twice a year (April and October). In addition, every two years, the so-called. Ubuntu LTS (short for “Long-Term Support”) is a version with long-term support, updates (including bug fixes and security) for which will be released over 5 years. Regular “interim” releases offer support for 9 months.

Ubuntu

Linux Mint

If you don’t like the look of the Ubuntu desktop, then you can look in the direction of Linux Mint. It is based on Ubuntu and is aimed at novice users, and you can use Cinnamon, Xfce, MATE, LXDE, or KDE as a desktop environment.

Linux Mint

Red Hat Enterprise Linux (RHEL)

Red Hat was founded in 1993. They have become arguably the most commercially successful Linux distribution company in the world, and are now owned by IBM.

Red Hat Linux (a distribution from Red Hat that was released between 1995 and 2003 inclusive) had nine major (free) releases of Linux distributions until in 2003 the company decided to focus on a commercial approach in Linux distribution.

As a result, Red Hat Enterprise Linux (RHEL) was created. This product is used by many companies around the world and is a commercial Linux distribution with full support. Most RHEL users use it as a server operating system, not a desktop one.

Red Hat Enterprise Linux (Rhel)

CentOS

CentOS is a free version of RHEL that is binary compatible with RHEL (i.e. it has the same software). Many companies that don’t need commercial support use CentOS.

Centos

Fedora

When Red Hat switched to a commercial distribution model for its products in 2003, it also released a distribution called Fedora. Fedora is a cutting-edge, completely free, desktop Linux distribution from Red Hat. By default, it uses the GNOME desktop, but as with Ubuntu, there are a large number of different Fedora-based builds. Since the Fedora distribution always strives to be at the cutting edge of technology, its stability may be lower compared to other distributions (Debian or Ubuntu LTS).

Note: Fedora has a reputation for focusing on innovation, integrating new technologies at an early stage, and working closely with other Linux communities.

Fedora

openSUSE

SUSE was once an independent German Linux distributor, which was later bought by Novell and then acquired by Micro Focus. Since then, they have been purchased and sold several times.

Like Red Hat, SUSE has also added a commercial distribution model to its distribution.

SUSE Linux Enterprise Server is a great all-in-one enterprise-focused product that includes a user support service, as well as corporate partnerships with companies like SAP. The commercial distribution model is not the only similarity between SUSE and Red Hat.

SUSE was originally built on Red Hat Linux and therefore has the same RPM-based package management system, but it has changed enough over the years to become a standalone distribution. SUSE’s Linux distributions use YaST as an operating system configuration and package installation utility.

The completely free version of Linux from SUSE is called openSUSE. There is also a version of openSUSE Tumbleweed, a system that constantly has new software updates (the so-called rolling release). In the distribution, you can find various software development tools, the openQA utility is designed for automated software testing, while Kiwi creates Linux images for deployment on real hardware. openSUSE uses the KDE desktop by default.

Opensuse

elementary OS

elementary OS is a desktop distribution based on Ubuntu. It is incredibly intuitive for a new user coming from a different system (especially from macOS). Some of its most interesting features include a custom desktop environment called Pantheon, which takes its cue from the look and feel of macOS.

Elementary Os

Gentoo Linux

Gentoo is a free operating system based on Linux, developed in 1992. Since software packages are collected from source codes directly on the user’s computer, the system can be automatically optimized and configured for almost any hardware or task.

The heart of Gentoo is portage, a powerful and flexible software configuration and distribution system (package manager) that performs many key functions. For example, when installing new software, portage automatically creates a custom version of the package that is optimized specifically for the target hardware, ensuring that the package does not contain unnecessary functionality that burdens your computer.

With portage, Gentoo can be the perfect secure server, developer workstation, embedded solution, or whatever else you want. Due to its almost unlimited adaptability, Gentoo is often referred to as a “smart OS”.

Gentoo Linux

Two Linux distributions based on Gentoo:

  • Sabayon Linux is a distribution based on Gentoo Linux released at the end of 2005, primarily aimed at novice users. According to the developers of Sabayon, their distribution follows the philosophy of “everything should work right out of the box”, while striving to provide the user with a large number of ready-to-use applications, unlike Gentoo with its sources, while maintaining the ability to optimize software packages for themselves.
  • Calculate Linux maintains an optimal balance between the latest software versions and perfect system performance, providing the user with the latest versions of applications and stable versions of libraries. As a rule, the use of Calculate Linux implies using it together with Calculate Directory Server, a directory service that provides centralized and managed software installation, mail storage, files, moving user profiles, etc. Since Calculate Linux is a rolling-release distribution (i.e., a distribution with a continuous update cycle), you install the system once and then only update it during the entire life of your hardware.

MX Linux

MX Linux (abbr. from MEPIS and antiX) is a lightweight Linux distribution based on the stable version of Debian, which is a joint development of the antiX and MEPIS Linux distribution community. It is positioned as a distribution package that is not very demanding on computer resources, combining a fairly good desktop environment with a high system stability indicator, sufficient performance, and simple configuration. Xfce, KDE, and Fluxbox are used as desktop environments.

Mx Linux

Kali Linux

Kali Linux (formerly known as BackTrack Linux) is a Debian-based Linux distribution containing several hundred programs and utilities aimed at solving various problems affecting information security aspects such as:

  • computer and network penetration testing;
  • web application vulnerability research;
  • computer forensics;
  • reverse engineering of software and much more.

You can choose from Xfce, GNOME, KDE Plasma, LXDE, MATE as an installable desktop environment. Kali Linux also supports a wide range of devices with processors based on the ARM architecture. The distribution is developed, funded, and supported by Offensive Security, a leading information security training company.

Kali Linux

Arch Linux/Manjaro/Slackware

Arch Linux is not derived from Debian or Red Hat Linux distributions. It stands apart and is revered by geeks for being an incredibly fast distribution because it is built on a simple (but solid) base. Everything else can be added via its package management system, pacman.

Arch Linux

Manjaro is a standalone distribution based on Arch Linux. It positions itself as a user-friendly desktop distribution. Both Arch Linux and Manjaro are rolling-release distributions.

Manjaro

Slackware was probably the first real Linux distribution since 1993! Like Arch Linux and Manjaro, it uses .tar.gz packages rather than the more popular apt or yum systems. If you consider yourself an advanced user but don’t want to bother compiling packages, Arch Linux or Manjaro might be the best choice for you, as they offer the same level of customization as Slackware.

Slackware

If you’re just starting with Linux, Arch Linux, Manjaro, and Slackware probably won’t be the best choice.

Zorin OS/Solus/Deepin

If you like distributions that have a similar look to that of Windows or macOS, or perhaps just something with a nice interface, then be sure to check out Zorin OSSolus, and Deepin. For example, Solus has its window manager called Budgie, and it was created entirely from scratch, rather than being a derived distribution from Ubuntu or Fedora.

So which distribution should you choose?

The following table summarizes the criteria for choosing a Linux distribution:

Distribution Package Brief description
Debian It provides stability and is recommended for advanced users.
Ubuntu It looks like macOS and is easy to use.
Linux Mint It looks like Windows and is suitable for beginners.
Red Hat Enterprise Linux (RHEL) For commercial use.
CentOS If you want to use Red Hat, but without its trademark.
Fedora If you want to use Red Hat and the latest software.
openSUSE It works the same as Fedora but is slightly older and more stable.
elementary OS Perfect for beginners and macOS fans alike.
Gentoo Linux For advanced users. Software packages are compiled from source codes directly on the target machine, and there are opportunities to optimize applications for specific computer hardware resources.
MX Linux A fast, responsive and recently gaining popularity Linux distribution that is suitable for both ordinary users and administrators.
Kali Linux Focused primarily on specialists in the field of the information security audit.
Arch Linux/Manjaro/Slackware For advanced users, because each package must be installed independently.
Zorin OS/Solus/Deepin If you want something different.
