One can distinguish between commercially backed distributions, such as Fedora ( Red Hat ), openSUSE ( Novell ), Ubuntu ( Canonical Ltd .), and Mandriva Linux ( Mandriva ), and entirely community-driven distributions, such as Debian, Mageia and Gentoo.

This can create some awkward situations for users of distributions derived from Debian.

Users can install Moodle from source, but this requires more technical proficiency than other automated approaches such as installing from a Debian package, deploying a ready-to-use TurnKey Moodle appliance or using the Bitnami installer.

Debian packages can be converted into other packages and vice versa using alien, and created from source code using CheckInstall or Debian Package Maker.

By default, Red Hat Enterprise Linux's up2date retrieves packages from a Red Hat Network ( RHN ) server, though users can add directories full of packages or even Debian and yum repositories if they wish.

NetZero has versions of its proprietary dial-up software for computers running Mac OS 9 or Mac OS X. NetZero previously offered a Linux version of the NetZero software advertised as being for Linspire, however the software could be installed on any Debian-based i386 or x86-64 Linux distribution ; NetZero can also be installed on any RPM-based Linux distribution as long as Alien is used to convert the NetZero Debian package into an RPM package.

QEMU can run the MIPS compiled version of Debian GNU / Linux on an x86 platform, along with Windows NT 3. 5, 3. 51 & 4. 0 with binaries here

Any SUSE Linux distributions or Debian installation with real resources assigned can be used as a virtual I / O server.

Progeny Debian aimed to be a model for developing a component-based Linux.

These include Netscape's implementation of SSL ( famously cracked by Ian Goldberg and David Wagner in 1995 ) and a Debian / Ubuntu edition of OpenSSL discovered in 2008 to be flawed.

It fails the Debian Free Software Guidelines, used by several Linux distributions, though it qualifies for the Free Software Foundation's Free Software Definition ; however, it is not compatible with the FSF's GNU General Public License, meaning that products derived from code under both the GPL and the QPL cannot be redistributed.

Dash became the replacement for ash in Debian and was expected to be the default / bin / sh for Debian Lenny.

The Open Source Initiative ( OSI ) has certified it as an open-source license, but the Debian project judged version 1. 1 to be incompatible with the DFSG.

By using Alien, Debian is LSB-compatible for all intents and purposes, but according to the description of their < tt > lsb </ tt > package, the presence of the package " does not imply that we believe that Debian fully complies with the Linux Standard Base, and should not be construed as a statement that Debian is LSB-compliant.

In general, Debian does strive to comply with the LSB, but there may be other limitations.

The < tt > debian-binary </ tt > file must be the first entry in the archive, otherwise it will not be recognized as a Debian package.

By 2000, most large-scale ( Mach-like ) efforts had ended, although OpenStep used an adapted Mach kernel called XNU, which is now used in the OS known as Darwin, which is the open source part of Mac OS X .. As of 2012, the Mach-based GNU Hurd is also functional and its inclusion in testing versions of Arch Linux and Debian in progress.

Despite this restriction, gnuplot is accepted and used by many GNU packages and is widely included in GNU / Linux distributions including the stricter ones such as Debian and Fedora.

deb is the extension of the Debian software package format and the most often used name for such binary packages.

The Schulze method is used by several organizations including Wikimedia, Debian, Ubuntu, Gentoo, and Software in the Public Interest.

FTBFS is used in output from apt-get ( a front-end to " dpkg ", which is the Debian package manager ).

Traditionally it has been used to call attention to a problem reported about a Debian package, early in its lifecycle.

It has also been used in Debian bug reports, to alert a developer to the presence of a problem.

However, since this is generalized symptom of a problem and is not specific to Debian, it may be used elsewhere.

dselect is a computer program used to manage software packages in the Debian operating system.

Debian GNU / Hurd is distributed on a live CD.

The Debian project, among others, have worked on the Hurd project to produce binary distributions of Hurd-based GNU operating systems for IBM PC compatible systems.

Initially it is impossible to find any mention of specific bugs on Microsoft's website, but later he notices that Microsoft has instated a system similar to the Debian one, though sugar-coated so as to not ruin the vision demanded by its customers.

In the same way, the Debian project has its own criteria, the Debian Free Software Guidelines, on which the Open-Source Definition is based.

The definition was based on the Debian Free Software Guidelines, written and adapted primarily by Bruce Perens.

The group adopted the Open Source Definition for open-source software, based on the Debian Free Software Guidelines.

In August 2011, the ARM-based Raspberry Pi credit card-sized computer was shown running a specially compiled ARM version of Quake III on the Debian Linux Operating System.

The added clause to the license was based on the original BSD license's advertising clause, which was viewed by the Free Software Foundation and Debian as incompatible with the GNU General Public License.

Some projects made releases ( notably OpenBSD 3. 5 and 3. 6, and Debian 3. 1 " Sarge ") based on XFree86 version 4. 4 RC2, the last version under the old license.

The OSI Open Source Definition and the Debian Free Software Guidelines specifically allow for restrictions on distribution of modified source code, given explicit permission to distribute both patches and source code.

Linspire was based on Debian ( and later Ubuntu ) with a KDE interface.

Exim 4 is currently the default MTA on Debian GNU / Linux systems.

Because the Debian approach diverges significantly from the Exim one it is common to find a lack of support for the Debian approach on the regular Exim mailing-lists and users are pointed towards the Debian-specific list.
