About LWN.net

The LWN.net Linux Distribution List

You have found the LWN.net Linux Distributions List. LWN has been tracking Linux distributions since 1999. Early versions of the list consisted of links on the side bars of the weekly Distribution page. By 2001 the list had grown to fill both sidebars of the weekly page, often trailing far below any actual mid-page content. So the list was moved to a flat file and released on October 11, 2001.

The next major release was on February 7, 2002. Additional information was added to each entry, and in the process links were fixed, entries moved to different categories and dead distributions were removed. Minor revisions have been made almost every week since then. A table of contents was added on May 9, 2002. There have been no major releases since then, however new distributions are added when found, dead distributions are removed when found, and link checking remains an ongoing (low-priority) process. Many thanks to Andrew Cater for a massive link-checking effort that took place in May 2020, resulting in a smaller and more up-to-date list.

We once hoped that this list would move to a searchable database, however that now seems unlikely to happen. We do hope you will enjoy this celebration of Linux diversity, with distributions large and small, specialized and generalized, old and new.

Table of Contents

    Leading Distributions

    Leading distributions have usually been around for a while and are well-established. They generally support several architectures and are translated into multiple languages. Some come from companies that supply service and support contracts for their products, others are community projects.

  1. Android
    http://www.android.com/
    Android is Linux without any GNU. Google backs Android, which can be found in the wild in phones, tablets and other devices. These devices usually contain proprietary software, and some of the available apps are proprietary as well. See the Android Open Source Project for the open source parts. Android was first announced November 5, 2007. Android 1.5 (Cupcake) was released April 30, 2009. Android 4.4 (KitKat) was released October 31, 2013. Android 5.1 (Lolipop) was announced March 9, 2015. Android 6.0 (Marshmallow) was released September 2015. Android 7.1.2 (Nougat) was released April 3, 2017. Android 8.1 (Oreo) was released December 5, 2017. Android 9 (Pie) was released August 6, 2018. Android 10 (no more names) was released September 3, 2019. Android 11 was released September 8, 2020.

  2. Debian GNU/Linux
    http://www.debian.org/
    The Debian Project is one of the oldest distributions, dating back to 1993, and is currently the largest volunteer-based distribution provider. Debian, the "universal operating system", has been translated into many languages; works on many hardware platforms; has a large repository with a wide variety of packages; includes experimental kernel variants for kfreebsd and the GNU Hurd; and has many derivatives. Debian Stable releases when ready, not on any fixed schedule, but stable releases happen about every two years and are supported for about 3 years. The LTS team provides commercial support for old-stable releases with security updates for a reduced set of packages after the Debian security team ends official support. The Debian testing branch (currently 11.0 "bullseye") is where the next stable release is prepared; packages are more current than stable while (usually) providing a stable desktop. The unstable branch (sid) is more bleeding edge, while the experimental branch contains packages that aren't yet ready for sid. Debian 12 will be named "bookworm" and Debian 13 "trixie". Debian 9.0 "stretch" was released June 17, 2017. The 13th and final stretch point release, Debian 9.13, was released July 18, 2020. The LTS team will take over maintenance of "stretch". Debian 10.0 "buster" was released July 6, 2019. The sixth buster point release, Debian 10.6, was released September 28, 2020.

  3. Fedora
    http://fedoraproject.org/

It is also a test-bed for Red Hat's Enterprise Linux products. The first Fedora Core release was dated November 5, 2003. Fedora strives for a new release every 6 months and releases will be supported for about 13 months. Fedora Editions include Workstation and Server, with CoreOS and IoT in preview.

Tumbleweed uses a rolling release model that updates to the latest stable software, with frequent snapshots. The more conservative openSUSE Leap is based on core SUSE Linux Enterprise (SLE) components with more up-to-date applications. Its releases follow SLE service packs, with the initial release (42.1) based on SLE 12 SP1. Leap 42.1 was was released November 4, 2015 and reached eol May 16, 2017.

It was released April 7, 2003 and was supported until May 1, 2004. Red Hat Enterprise Linux comes with service and support contracts for those Red Hat customers who require a stable, supported system. There are a number of other Red Hat products for cloud environments. Red Hat was acquired by IBM in July 2019, however no changes are planned for RHEL products and services, or for Fedora and CentOS. Supported versions: RHEL 7 was released June 10, 2014; now at update 7.9, released September 29, 2020. RHEL 8 was released May 7, 2019, now at update 8.3, released October 29, 2020.

In essence, Porteus is a portable Slackware which started out as Fanthom keeping the Slax OS up to date as a community remix project. Unlike a standard linux install, Porteus exists in a compressed state on the portable drive. It has no /root /bin /etc file structure on the portable device itself, rather this is created on the fly during the boot process, which only takes around 20-30 seconds on a relatively new computer. It is modular in design which means extra software comes in the form of 'modules' which can be activated and injected into the live file system. It does not need to be installed and uninstalled as you may expect with other operating systems which takes numerous amounts of clicks and agreements. Porteus joined the list with the release of version 1.0 rc2 x86_64, dated May 7, 2011. Porteus 1.0 was released June 20, 2011. Porteus 3.2.2 was released December 29, 2016.
