There is no single distribution of the Linux software. Instead, there are many such distributions, available both via anonymous FTP and by mail order on CD-ROM.
The purpose of this document is to provide short summaries of the English-language Linux CD-ROM distributions, and to provide pointers for the reader to find more information. A German Distributions HOWTO was formerly maintained by Marco Budde but seems to have disappeared. We are not aware of any distributions in languages other than English and German.
The information presented here is not complete; there are other Linux distributions than are listed here. By the nature of open source software, anyone that changes anything in their Linux installation and makes it available to others somehow is `a distribution'. A document such as this has to pick somewhere to draw the line. I have picked `available on CD'. This is by no means the definition of a Linux distribution. There are numerous small distributions that offer things the big distros don't, not the least of which is smallness itself.
The information presented here is not complete; there are other Linux distributions than are listed here. If you are associated with a CD-ROM distribution we don't list, please see Submissions To This Document near the end of this document for information on making a submission. It's easy and should take less then five minutes.
For a more complete list of distributions (albeit with sparser information on each) see the Linux HQ Distributions List.
Disclaimer: We make absolutely no guarantee as to the correctness of the information, prices, and ordering details given in this document. Check the last-modified field of each to get an idea of its currency, then go to the vendor's web page for up-to-date information. Furthermore, unless otherwise stated the Linux software comes with ABSOLUTELY NO WARRANTY.
Your editor tries to stick to facts in most of this HOWTO, but he has some opinions on the state of the Linux market. If you care what they are, you can read them under Editorial Recommendations.
Disclosure: I (esr) have no financial connection to any Linux vendor, nor have I accepted any renumeration or perquisites from any vendor other than free product for review (and one T-shirt from Red Hat).

choosing a distribution unless you're willing to hire me at

and I try to put everything I know about choosing a
distribution in this document.
Yggdrasil Plug-And-Play and Craftworks Linux seem no longer to be available for sale, and have been dropped. DOSLINUX has also been dropped due to its specialist nature. KRUD, Linux-Mandrake, and LinuxGT have been added.
In the beginning (say, 1993), a Linux distribution was something you downloaded off the Internet onto floppies. Installation was a laborious process and repeated frustrations due to bad media were common.
Then came cheap CD-ROM drives and the CD-ROM, a medium ideally suited for shipping large volumes of operating-system software cheaply. There's a whole mini-industry now built around commercial CD-ROM Linuxes, and (because the vendors have actual cash flow to fund support and marketing) they increasingly dominate the Linux world. Debian is now the only significant non-commercial release, and even it seems to be propagated largely by shovelware CD-ROMs.
Most of the CD-ROM distributions (including Slackware, Yggdrasil and Red Hat) are still available for FTP from the home sites of their developers. But if you have a CD-ROM drive and a few dollars, you will have many more distributions and more support options to choose from (and you'll usually get some useful paper documentation). For more on the details of installation, see the Linux Installation HOWTO, http://metalab.unc.edu/mdw/HOWTO/Installation-HOWTO.html.
Prices for CD-ROM distributions of Intel Linuxes start at $20 and top out at a whole $50 (and the extra few dollars can buy real value). Many vendors sell subscription deals that will lower your cost-per-CD for regular updates over the subscription period.
Price correlates with features and quality pretty well (as one would expect in a very competitive market). Your editor recommends paying the few extra dollars for a top-drawer original CD-ROM distribution; this will pay off in fewer installation and administration hassles down the road.
Making good choices is much simpler than it used to be. In 1995-96 the Linux market underwent a serious shakeout, with a very few commercial distributions emerging as leaders while weaker ones disappeared or stagnated. The toll among general-purpose non-commercial distributions has been even fiercer; essentially, only Debian survives in this role.
As a result, the three-tier structure of primary distribution builders, value-added repackagers, and bottom-feeding CD shovellers that used to define the market has nearly collapsed. To be competitive in the third millennium, a Linux outfit (whether commercial or noncommercial) has to offer reasonable support and behave like a primary distribution builder, whether it's really one or not. So as long as you look for a recent freeze date, it is pretty hard to get stuck with a dud distribution these days.
Last section, the facts. In this section, my opinions (for whatever they're worth -- and remember the caveat about free advice). There is no substitute for doing your own evaluation based on experience and the data in this guide, and these are intended more to illuminate my possible biases than as a guide to what you should do.
From the beginnings of the Linux CD-ROM industry in 1993 to Fall 1995, Yggdrasil was the king of the hill -- it essentially founded the CD-ROM market and then set the standard for everybody else. I used Yggdrasil, and I recommended it over commercial System V versions for its superior documentation, large collection of applications, and enlightened policy of sending free releases to open-source authors and dedicating part of the price of each CD-ROM to financially supporting free software. But Yggdrasil hasn't issued a new release since 1995 and they've been left behind by the market.
I now run Red Hat Linux and am quite satisfied with it. They have successfully created a de-facto standard in distribution packaging with RPM (now also used by SuSE and Mandrake, among others). They've made most of the right moves at the right times and I consider them the current market leader.
If you're ideologically wedded to using a non-commercial distribution, Debian seems to me to be the clear choice, the only one left with a serious support team behind it.
These opinions should certainly not be interpreted as an unconditional endorsement; different Linux distributions are optimized for different needs, and yours may well be best served by some other distribution (especially if, unlike me, you're mainly a DOS user and are looking for a distribution tuned for dual-boot systems and being launched from DOS).
Furthermore, industry standing is volatile. By the time you read this, Red Hat or Debian may well have fallen off their games and been displaced by hungrier newcomers.
All these distributions are available on CD-ROM (some of the non-commercial ones only show up on network-archive snapshots). Most of these are available for free over the network (but the commercial ones won't support you if you buy this way). They are custom-assembled, rather than just being re-packagings of a pre-existing network release.
They are listed in alphabetical order.

Caldera is shipping OpenLinux 1.2 in a three-tiered family of products: OpenLinux Lite, OpenLinux Base, and OpenLinux Standard.
OpenLinux Lite is a freely available evaluation of the OpenLinux product (it includes a 90-day evalutation of the Caldera integrated Desttop--the full licensed version of the desktop is included in the Base and Standard products). OpenLinxu Lite can be downloaded from Caldera's ftp site, or obtainded on CD for the cost of shipping. It is also designed for use by book and software publishers to provide a commercially stable Linux offering with their books and software products.
OpenLinux Base contains everything that is in Lite plus it is a complete, easy-to-install Linux operating system, with integrated Desktop, Internet client and server components, and Intranet connectivity. OpenLinux Base includes Netscape Navigator and full documentation.
OpenLinux Standard includes what is in Base plus more high-end, name brand, commercial software components (such as Netscape FastTrack Web Server, Netscape Navigator Gold Web browser and authoring tools, ADABAS D database, StarOffice productivity suite, Caldera OpenDOS, and NetWare client and administration tools).
All three tiers of the OpenLinux 1.2 release are currently available.
With Caldera OpenLinux, you can see a whole world of powerful new computing, even the power of a UNIX workstation on your PC! By using a Linux kernel, OpenLinux gives you speed and stability that compare to systems costing thousands of dollars. Open Linux also gives you:
No other Linux system includes a complete, integrated desktop interface with configuration tools and graphical editor. Its powerful drag-and-drop capabilities come pre-configured with thousands of icons and application settings. The Desktop provides a convenient place where you can store your favorite programs and data files for instant access. The Desktop gives you:
By email with PGP key, by phone, by fax, or by conventional mail. Full ordering details are at http://www.caldera.com/mpro/orinfo/orderinfo.html.

Debian Linux is the result of a volunteer effort to create a high-quality non-commercial Linux distribution. Debian Linux 2.0 is a complete and fully-functional Unix-compatible operating system for the personal computer. The system uses ELF executables and libc6 (unlikeprevious Debian versions, which used libc5). At present, Debian Linux is available for the IBM PC architecture (386/486/Pentium) and m68k, with versions for Sparc and Alpha promised for 2.1. ARM, PPC, and UltraSparc ports are underway.
Debian Linux is an easy-to-upgrade distribution that mostly consists of freely redistributable software from a number of different sources and systems. Support for shadow passwords is available, although it should be considered experimental in the 1.1 release. Non-free packages may also obtained, making Debian a well-rounded system.
The benefits of Debian Linux are its upgradability, well-defined dependencies between packages, and its open development. It is the only distribution of Linux that is being developed co-operatively by many individuals through the Internet, in the same spirit as Linux and other open-source operating systems. More than 400 package maintainers are working on over 1500 packages and improving Debian Linux. A sophisticated bug tracking system allows users to easily report bugs and security concerns which are quickly dealt with by the Debian community. A new release of the package will soon occur on well-known ftp archives.
Debian Linux is a very dynamic distribution. Snap-shot releases are made about every three months, the ftp archives are updated daily.
For more information about Debian Linux, please refer to the files at ftp://ftp.debian.org/debian/doc/ or visit our World Wide Web page at http://www.debian.org/. There is also a book, "Running Debian GNU/Linux", from O'Reilly & Associates.
If you're interested in joining this project you are invited to subscribe to either firstname.lastname@example.org or email@example.com by sending a mail to firstname.lastname@example.org (or debian-devel-request respectively) with the word "help" in the subject line.
Debian Linux is available via anonymous FTP from ftp://ftp.debian.org/debian/ and on a mirror near to you.

The charter of the WGS Linux Pro CD is different from all other distributions currently on the market. We are actively pursuing penetration into the commercial marketplace for Linux. Everything we do is aimed at increasing the size of the Linux community, and helping Linux to become THE one true operating system, not just an operating system.
WGS Linux Pro consists of our Main "Stable" Linux CD, for which we select what we consider to be the best Linux distribution available. Then we make bug fixes & minor enhancements. This CD often contains software older than the latest, under the theory that "the latest is not always the greatest". Together with this approach we provide technical support as well as support agreements. For this reason WGS Linux Pro is considered a primary Linux distribution. Optionally, and in addition to our primary CD, we supply supplemental CDs containing all the latest Linux software (including current archives of the tsx-11, metalab, and Red Hat sites). Virtually anything you will get with anyone's Linux product can be found on these supplemental CDs. We continually add more to these supplemental CDs as software becomes available. Even with all this, pricing on our product line is very favorable when correctly compared to other Linux distributions. Also optional (included with Linux Pro+) is a professionally produced and printed manual containing the Linux documentation project and more!
Current version is 4.0a; kernel is 1.2.13 with installable 2.0.x on the CD.
Look in http://www.wgs.com for a list of WGS products, and latest information on the CD-ROM.
WGS Linux Pro is available on CD from dealers and distributors worldwide, and soon from our FTP site.
You may call, fax, email, or mail us, to purchase, or request additional information. We will be happy to respond to any question you have. We accept American Express, Visa, Discover, and MasterCard, or purchase orders with approval of credit.
Complete information is available on our FTP site.
WGS publishes a free E-Mail newsletter on Linux and FlagShip to which you may subscribe by just emailing us your request.
In addition we carry Motif, FlagShip, A line of books, and other products to make your experience with Linux more complete and fulfilling. Check us out!

Red Hat 6.1 is based on the 2.2 kernel and is available for Intel, Sparc and Alpha platforms.
Four installation innovations make Red Hat the easiest Linux to install ever. Our graphical installation mode brings you straight up into X for most of the installation. Our boot disk creation script eases selection of the proper boot disk, and it saves your existing network configuration information and XF86Config so you don't have to configure TCP/IP or X! Our FTP install allows you to install simply by downloading 3 floppy disk images -- the rest is done automatically! And finally, the installation includes seamless support for PCMCIA devices -- install Red Hat on your laptop as easily as on your desktop machine!
After installing Red Hat Linux once, you will never need to reinstall Linux again! The new RPM packaging system is sophisticated enough to allow upgrading to new Red Hat releases without reinstalling your system - no partitioning, no backing up all your files, no headaches.
Available directly from Red Hat Software and most distributors of Linux related products. Please contact Red Hat Software for ordering details (on-line ordering is available through Red Hat's Web). Suggested retail price for the Standard version is $29.95; for the Professional (server) version $149.95; for the Deluxe version $79.95.
1 Nov 1999.
The big selling point of this distribution is RPM, the Red Hat Package Manager. This piece of software is a remarkable advance; it allows you to cleanly install and de-install applications and operating-system components, including the kernel and OS base itself. RPM is now used as well by essentially all other distributions except Debian.

I encourage anyone and everyone who maintains a Linux distribution or mail order service, to submit information on their service to this HOWTO. It's easy and fun, and it's free advertising. This document is posted to many places and is archived (see the next section).
We are interested in submissions for:
If the number of submissions for services and layered products is large, I'll create a separate HOWTO for these items.
To submit an entry to this HOWTO, please send mail to
firstname.lastname@example.org with the following information. This
format is not machine-parsable; any of the fields may be any
length that you wish, but I'd like to keep each entry down to,
say, 50 lines.
Name of service or distribution
Name of company, person, etc. who distributes/maintains the service or distribution. Should include mail, email, phone contact information, and (if possible) a WWW reference.
Description of the distribution or service that you provide. If this is a software distribution, please include information such as what software is included, versions, general overview of installation, requirements, and so on.
Where your service or distribution is available over the Internet; typically a WWW or FTP address.
How to order your distribution or service, if applicable. Include prices, shipping information, methods of payment, etc.
Information on support terms and support contracts.
Anything else that you find relevant.
Last freeze date of the current version(s). Also, your estimated update frequency.
Please keep your entry as short as possible. If you need to include extensive information, please make a reference to where one can FTP or mail to get more information on your distribution; these entries are only meant to be pointers to where one can find information on your service or distribution.
If you provide more than one service or distribution, please use separate entries for each.
I may edit your entries for conciseness and brevity, if I find any irrelevant information, or if the entry is overly verbose. Otherwise the content should remain the same.
When making submissions to the Distribution-HOWTO, you grant implicit permission for me to use the entries in other materials, such as books from the LDP, and other online documents. For example, information from the Distribution-HOWTO may be included in a published Linux book. If you do not want me to include your entry in materials other than the Distribution-HOWTO, please say so.

These restrictions are intended to protect potential readers from stale or mangled versions. If you think you have a good case for an exception, ask me.
This document was originated by Bill Riemers. Matt Welsh maintained the second version. Erik Troan then maintained the document to release 3.0.
In January 1995, Eric Raymond, while unaware of the existence of this document, began to develop a similar FAQ in the format of his now-discontinued "PC-clone UNIX Software Buyer's Guide", which had covered mainly System V UNIXes and BSD/OS.
In March 1995, Eric approached Erik about cooperating on a merged version. In early April 1995, Erik went to work for Red Hat Software, and (wishing to avoid a conflict of interest) handed the document to Eric. Eric merged in a lot of new information and added several new fields to the distribution entries.
Accordingly, this document has been a sort of serial collaboration. The editorial `we' generally tags observations by all the maintainers; `I' is Eric (the current one) speaking.
We are delighted to acknowledge the contributions of all the Linux users and Internet hackers who have contributed information and feedback.
