openSUSE[5] ( /ˌoʊpənˈsuːzə/) is a free and open-source Linux distribution developed by the openSUSE project. It is offered in two main variations: Tumbleweed, an upstream rolling release distribution, and Leap, a stable release distribution which is sourced from SUSE Linux Enterprise.[6]

The openSUSE project is sponsored by

workstations and servers.[8]

Additionally, the project creates a variety of related tools, such as YaST, Open Build Service, openQA, Snapper, Portus, KIWI, and OSEM.

Product history

SuSE Linux 7.1, released January 24, 2001, with the older KDE 1.1.2 desktop

In the past, the SUSE Linux company has focused on releasing the SUSE Linux Personal and SUSE Linux Professional box sets which included extensive printed documentation that was available for sale in retail stores. The company's ability to sell an open-source product was largely due to the closed-source development process used. Although SUSE Linux had always been a free software product licensed with the GNU General Public License (GNU GPL), it was only freely possible to retrieve the source code of the next release 2 months after it was ready for purchase. SUSE Linux' strategy was to create a technically superior Linux distribution with a large number of employed engineers, that would make users willing to pay for their distribution in retail stores.[9]

Since the acquisition by

ISO image of SUSE Professional was made available for download. The FTP server continues to operate and has the advantage of "streamlined" installs, allowing the user to download only the packages the user feels they need. The ISO has the advantages of an easy install package, the ability to operate even if the user's network card does not work "out of the box," and less experience needed (i.e., an inexperienced Linux user may not know whether or not to install a certain package, and the ISO offers several preselected sets of packages).[citation needed
]

SUSE Linux 10.0, released October 6, 2005, was the first release of the openSUSE Project.

The initial stable release from the openSUSE Project, SUSE Linux 10.0, was available for download just before the retail release of SUSE Linux 10.0. In addition, Novell discontinued the Personal version, renaming the Professional version to simply "SUSE Linux," and repricing "SUSE Linux" to about the same as the old Personal version. In 2006, with version 10.2, the SUSE Linux distribution was officially renamed to openSUSE, as it is pronounced similarly to “open source”.[10][11] Until version 13.2, stable fixed releases with separate maintenance streams from SLE were the project's main offering. Since late 2015, openSUSE has been split into two main offerings, Leap, the more conservative fixed release Leap distribution based on SLE, and Tumbleweed, the rolling release distribution focused on integrating the latest stable packages from upstream projects.[12]

Over the years, SUSE Linux has gone from a status of a distribution with restrictive, delayed publications (2 months of waiting for those who had not bought the box, without ISOs available, but installation available via FTP) and a closed development model to a free distribution model with immediate and free availability for all and transparent and open development.[13]

On April 27, 2011, Attachmate completed its acquisition of Novell. Attachmate split Novell into two autonomous business units, Novell and SUSE. Attachmate made no changes to the relationship between SUSE (formerly Novell) and the openSUSE project. After the 2014 merger of the Attachmate Group with Micro Focus, SUSE reaffirmed its commitment to openSUSE.[14]

EQT Partners announced their intent to acquire SUSE on July 2, 2018. There are no expected changes in the relationship between SUSE and openSUSE. This acquisition is the third acquisition of SUSE Linux since the founding of the openSUSE Project and closed on March 15, 2019.[15]

The openSUSE Project is a community project to create, promote, improve, and document the openSUSE Linux distribution.[16]

The

Arm, B1-Systems, Tuxedo Computers and others, develops and maintains various distributions based on Linux.[citation needed
]

Beyond the distributions and tools, the openSUSE Project provides a web portal for community involvement. The community develops openSUSE collaboratively with its corporate sponsors through the

Internet Relay Chat channels, and improving the openSUSE site through its wiki interface.[citation needed
]

The openSUSE Project develops free software and tools and has two main Linux distributions named openSUSE Leap and openSUSE Tumbleweed. The project has several distributions for specific purposes like MicroOS, which is an immutable operating system that hosts container workloads, and the Kubernetes certified distribution Kubic, which is a multi-purpose standalone and Kubernetes container operating system based on openSUSE MicroOS. The project is sponsored by a number of companies and individuals, most notably SUSE, AMD, B1 Systems, Heinlein Support, and TUXEDO Computers.[17]

The first indication that there should be a community-based Linux distribution called OpenSuSE goes back to a mail of August 3, 2005,[18] in which at the same time the launch of the website opensuse.org was announced. This page was available a few days later.[19] One day later the launch of the community project was officially announced.[20]

According to its own understanding, openSUSE is a community that propagates the use of Linux and free software wherever possible.[21][22] Beside a Linux-based distribution it develops tools like the Open Build Service and YaST. Collaboration is open to everyone.

Activities

The openSUSE Project develops the openSUSE Linux distribution as well as a large number of tools around building Linux distributions like the Open Build Service, KIWI, YaST, openQA, Snapper, Portus, and more. The project annually hosts free software events. The community's conference is held at a location in Europe and a summit is held at a location in Asia.[citation needed]

Organization

The project is controlled by its community and relies on the contributions of individuals, working as testers, writers, translators, usability experts, artists, and developers. The project embraces a wide variety of technology, people with different levels of expertise, speaking different languages, and having different cultural backgrounds.[23]

There is an openSUSE Board which is responsible to lead the overall project. The openSUSE Board provides guidance and supports existing governance structures but does not direct or control development, since community mechanisms exist to accomplish the goals of the project. The board documents decisions and policies.[citation needed]

The project is self-organized without a legal structure, although the establishment of a foundation has been under consideration for some time.[24]

SUSE as the main sponsor exerts some influence, but the project is legally independent of SUSE. openSUSE is a "do-ocracy" in which those who do the work also decide what happens. This primarily the case with desktop and application development, as the sources of the base packages have been coming from

SLE's binary packages.[citation needed
]

Organizational units

There are three main organizational units:

  • openSUSE Board: the board consists of 5 members elected for 2 years at a time, plus the chairman, who is provided by SUSE.[26] The Board serves as a central point of contact, helps with conflict resolutions and communicates community interests to SUSE. As of January 2023, the Board has the following members:
    • Douglas DeMaio (US)
    • Dr. Gerald Pfeifer (AT), Chair
    • Gertjan Lettink (NL)
    • Maurizio Galli (CH)
    • Neal Gompa (US)
    • Patrick Fitzgerald (UK)
  • Election Officials: The Election Committee manages and supervises the elections to the openSUSE Board. It consists of three or more volunteers.[27]
  • Membership-Officials: The Membership-Officials[28] are appointed by the Board if interested. The Membership-Officials decide on the admission of contributors to the group of openSUSE members upon request. A member receives, among other things, an @opensuse.org address. Only members may vote in the election to the Board.

Current distributions

openSUSE Tumbleweed

openSUSE Tumbleweed Logo
openSUSE Tumbleweed Logo

Tumbleweed is the flagship of the openSUSE Project. Instead of classical version numbers and periodic updates, a rolling release system is used: updates happen continuously; previous states of the operating system are saved as "snapshots". Tumbleweed is preferred by openSUSE users as a desktop system.[29]

In the old development model, with each new openSUSE release (13.0, 13.1,...) a new rolling release was set-up, which always received new packages. When the new release was at the doorstep, and Tumbleweed was reset to that release, most packages were newer than the ones in the release, which led to problems.[citation needed]

With the switch to Leap, the development model was changed completely: according to the Factory First policy all software packages had to be sent to Factory in the first place before they could be included in a distribution. Out of Factory a daily snapshot is taken and tested in openQA. A successful test is released as the next Tumbleweed snapshot. Unlike other rolling release distributions, Tumbleweed is a tested rolling release, which increases stability dramatically.[30]

Technically Tumbleweed is the basis for MicroOS and Kubic.[31]

openSUSE Leap

openSUSE Leap Logo

Leap is a classic stable distribution approach: one release each year, and in between, security updates and bug fixes. This makes Leap very attractive as a server operating system,[32] as well as a desktop operating system,[33] since it requires little maintenance effort.

For the version released in the fall of 2015, the development team settled on the name openSUSE Leap with the deviating version number 42.1. As in the openSUSE version 4.2 from May 1996, which was called S.u.S.E. Linux at the time, the number

SUSE Linux Enterprise, while applications and desktops come from Tumbleweed.[citation needed
]

At the openSUSE conference held in Nuremberg in 2016, statistics were announced that since the conceptual reorientation with openSUSE Leap 42.1, increasing user numbers had been recorded.

updates
. Thus, the number of Tumbleweed installations had doubled in the last year.

Other findings from the statistics are that most installations are done via DVD images. The dominant architecture is

x64. The geographical distribution of users has hardly changed according to these figures. One-third of users are from Germany, 12% are found in the US, 5% in Russia, and 3% in Brazil.[34]

For the openSUSE Leap 15.3 release, the repository for openSUSE Leap and SUSE Linux Enterprise (SLE) was merged and now contains the same source code and binary packages.[35] SLE 15 will be supported until 31 July 2028.[36]

openSUSE MicroOS

MicroOS

container runtime. Some even use it as desktop system.[38]

The system is self-contained and transactional; it updates itself in an all-or-nothing approach (transactional) and rolls back to its previous stage in case something goes wrong. It runs from a read-only file system, preventing accidental changes and malware attacks. The transactional update does not affect the running system.

All software available for Tumbleweed is also available for MicroOS. As it comes with

podman
Container-Runtime, MicroOS is advertised as "the perfect Container-Host."

MicroOS Desktop was the focus for the 2021 Hackweek.

On May 31, 2023, OpenSUSE announced name changes: the Gnome version of MicroOS is now called Aeon, and the Plasma version is called Kalpa.[39]

Factory project

The Factory project is the rolling development code base for openSUSE Tumbleweed,[40] Factory is mainly used as an internal term for openSUSE's distribution developers, and the target project for all contributions to openSUSE's main code base. There is a constant flow of packages going into the Factory. There is no freeze; therefore, the Factory repository is not guaranteed to be fully stable and is not intended to be used by humans.

The core system packages receive automated testing via openQA. When automated testing is completed and the repository is in a consistent state, the repository is synced to the download mirrors and published as openSUSE Tumbleweed, That usually happens several times a week.[41]

Supported Architectures

openSUSE currently (2023) supports installation via

Vagrant, and VirtualBox
. It can also be installed in conventional virtualization environments with a range of architectures e.g. using VirtualBox, VMWare, or Hyper-V.

Features

YaST Control Center

Main article: YaST

SUSE includes an installation and administration program called YaST ("Yet another Setup Tool") which handles hard disk partitioning, system setup, RPM package management, online updates, network, and

firewall configuration, user administration and more in an integrated interface. By 2010, many more YaST modules were added, including one for Bluetooth support.[42]
It also controls all software applications. SaX2 was once integrated into YaST to change monitor settings, however, with openSUSE 11.3 SaX2 has been removed.

The GTK user interface was removed starting with Leap 42.1, however, the ncurses and Qt interfaces remain.

AutoYaST is part of YaST2 and is used for automatic installation. The configuration is stored in an XML file and the installation happens without user interaction.

WebYaST

WebYaST
is a web interface version of YaST. It can configure settings and updates of the openSUSE machine it is running on. It can also shut down and check the status of the host.

ZYpp package management

Main article: ZYpp

ZYpp (or libzypp) is a Linux software management engine. ZYpp is the backend for zypper, the default command line package management tool for openSUSE.

Build Service

Main article: Open Build Service

The

GNU GPLv2+.[43]

Default use of Delta RPM

By default, OpenSUSE uses

Delta RPMs
when updating an installation. A Delta RPM contains the difference between an old and a new version of a package. This means that only the changes between the installed package and the new one, are downloaded. This reduces bandwidth consumption and update time, which is especially important on slow Internet connections.

Desktop innovation

KDE

SUSE was a leading contributor to the

KDEBase, Kontact, and kdenetwork. Other notable projects include: KNetworkManager – a front-end to NetworkManager[44] and Kickoff – a new K menu for KDE Plasma Desktop.[45]

From openSUSE Leap 42.1 to 15.0, the default

Plasma 5 desktop for openSUSE used the traditional cascading Application Menu in place of the upstream default Kickoff-like Application Launcher menu. The openSUSE Leap KDE experience is built on long-term support versions of KDE Plasma, starting with openSUSE Leap 42.2.[46]
With openSUSE Leap 15.1, the Plasma 5 desktop now again defaults to the Kickoff-style application menu.

GNOME

GNOME 3.26 under openSUSE 15.1. openSUSE Leap's GNOME implementation has used Wayland by default since version 15.0.

The

Banshee
. The GNOME desktop used the slab instead of the classic double-panelled GNOME menu bars from openSUSE 10.2 to openSUSE 11.4. In openSUSE 12.1 slab was replaced with the upstream GNOME Shell and GNOME Fallback designs.

Starting with openSUSE Leap 15.0, GNOME on

GNOME Classic
, GNOME on Xorg, and "GNOME SLE" are offered as alternative sessions to the more upstream Wayland-based session.

Releases

10.x series

The initial stable release from the openSUSE Project was SUSE Linux 10.0, released on October 6, 2005.

ISO image and as a boxed retail package, with certain bundled software only included in the retail package.[49]

On May 11, 2006, the

openSUSE Project released SUSE Linux 10.1, with the mailing list announcement identifying Xgl, NetworkManager, AppArmor and Xen as prominent features.[50]

For their third release, the openSUSE Project renamed their distribution, releasing openSUSE 10.2 on December 7, 2006. Several areas that developers focused their efforts on were reworking the menus used to launch programs in KDE and GNOME, moving to

Mozilla Firefox
.

The fourth release, openSUSE 10.3, was made available as a stable version on October 4, 2007.

1-Click-Install), legal MP3 support from Fluendo
and improved boot-time are some of the areas focused on for this release.

11.x series

openSUSE 11.0 was released on June 19, 2008. It includes the latest version of GNOME and two versions of KDE (the older, stable 3.5.9 and the newer 4.0.4).[52][53] It comes in three freely downloadable versions: a complete installation DVD (including GNOME, KDE3, and KDE4), and two Live CDs (GNOME, and KDE4 respectively). A KDE3 Live CD was not produced due to limited resources.[53] Package management and installation were made significantly faster with ZYpp.[54]

openSUSE 11.1 was released on December 18, 2008. Updated software includes

Xserver 1.5.2, and Linux kernel 2.6.27.7.[55] openSUSE 11.1 was the first Evergreen supported release.[56]

openSUSE 11.2

hybrid and now support both USB and CD-ROM boot.[59][60]

openSUSE 11.3 was released on July 15, 2010. It includes Plasma 4.4.4, GNOME 2.30.1,

Mozilla Firefox 3.6.6, OpenOffice.org 3.2.1, SpiderOak support, support for the Btrfs filesystem and support for LXDE. It also updates the Linux kernel to version 2.6.34.[59]

openSUSE 11.4 was finished on March 3, 2011, and released on March 10, 2011. It includes Plasma 4.6.0, GNOME 2.32.1,

Mozilla Firefox 4.0 beta 12, and switched from OpenOffice.org to LibreOffice 3.3.1. It updates the Linux kernel to version 2.6.37.[61]

12.x series

openSUSE 12.1 was released on November 16, 2011. This includes Plasma 4.7 and GNOME 3.2 and Firefox 7.0.1. The Linux kernel was updated to 3.1.0[62] It also introduced an advanced disk snapshot tool, called Snapper, for managing Btrfs snapshots.[63] openSUSE 12.1 was also the first release of openSUSE to use systemd by default rather than the traditional System V init. Users can still select to boot to System V init at startup time.

openSUSE 12.2 was to be released on July 11, 2012, but was postponed due to persistent stability issues.[64] The final release candidate was eventually announced on August 2, 2012, and the final release date was September 5, 2012.[65] 12.2 includes the desktop environments Plasma 4.8, GNOME 3.4, Firefox 14.0.1, and Xfce 4.10 and now uses Plymouth and GRUB 2 by default.

openSUSE 12.3 was released on schedule on March 13, 2013. This includes Plasma 4.10, GNOME 3.6, Firefox 19.0, LibreOffice 3.6, and the removal of SuSEconfig. Also, the Live CD images were replaced with Live USB images, and an Xfce rescue image.

13.x series

openSUSE 13.1 was released on November 19, 2013, and includes updates to Plasma 4.11, GNOME 3.10, Firefox 25.0, and LibreOffice 4.1. Some other changes include a YaST port to Ruby, the LightDM KDE greeter, and experimental Wayland support in the GNOME Shell and KDE Plasma Desktop. openSUSE 13.1 is an Evergreen supported release, meaning it will receive community patches for 18 months after SUSE support ends.[66]

openSUSE 13.2 was released on November 4, 2014, and includes updates to Plasma 4.11, KDE Applications 4.14, GNOME 3.14.1, Firefox 33.0 and LibreOffice 4.3.2.2.

Leap 42.x series

The openSUSE team decided that the next version would be based on

the answer to life, the universe and everything);[67]
this was a temporary anomaly in the version number sequence, as the following release series was numbered 15.X.

Leap 42.2 features KDE Plasma 5.8 LTS as its default desktop environment.[68]

Leap 15.x series

openSUSE Leap 15[69][70] is based on SUSE Linux Enterprise (SLE). The name "Leap 15" is meant to match the SUSE Linux Enterprise version it is based on. Leap 15 (just like SUSE Linux Enterprise 15) uses Linux kernel 4.12 LTS, and the default desktop is KDE Plasma 5.12 LTS. It also allows users to switch to its enterprise variant - SUSE Linux Enterprise 15. The latest Leap 15.5 (released on 7 June 2023) uses Linux kernel 5.14.21, KDE Plasma 5.27 and comes with a new support of Python 3.11.[71] It is expected to be the penultimate release of Leap 15, with version 15.6 scheduled to be released in early June 2024.[72]

Version history

Starting with version Leap (after version 13.2), each major release (e.g. 15.0) is expected to be supported for at least 36 months, until the next major version is available (e.g. 16.0), aligned with SUSE Linux Enterprise Releases. Each minor release (e.g. 15.5, 15.6 etc.) is expected to be released annually, aligned with SUSE Linux Enterprise Service Packs, and users are expected to upgrade to the latest minor release within 6 months of its availability, leading to an expected support lifecycle of 18 months.

Tumbleweed[73][74] is updated on a rolling basis, and requires no upgrades beyond the regular installation of small updates and snapshots.[75]

Evergreen[56] was a community effort to prolong maintenance of selected openSUSE versions after they reached official end-of-life before the Leap series.

From 2009 to 2014, the openSUSE project aimed to release a new version every eight months. Prior to the Leap series, versions 11.2-13.2 were provided with critical updates for two releases plus two months, which resulted in an expected support lifetime of 18 months.[76][77]

Version timeline

Derivatives

The project has spawned a few forks and derivative versions over the years, namely SUPER, SLICK Linux,[115] FyreLinux, Gibux (for the Turkish Revenue Administration), Lietukas Linux, Nelson GNU/Linux-libre, Edu Li-f-E, Linux Kamarada,[116] and GeckoLinux.[117]

Reception

Jesse Smith from DistroWatch Weekly reviewed openSUSE Leap 15.0, lauding the "work that has gone into the system installer", simplify for new users, but criticized the lack of media support, and performance issues, like a slow startup or slow shutdown.[118]
