A

Adoption

The process of taking over as maintainer of a package that has been orphaned or tagged RFA

Advocate

A Debian member who advocates an application. Advocates should know the applicant fairly well and should be able to give an overview of the applicant's work, interests, and plans. Advocates are often the sponsors of an applicant.

Alioth

Alioth is a collaborative development environment based on the FusionForge software as a service for the Debian project and community.

Alioth (guest) account

People willing to participate in the packaging or development of a software can ask for an Alioth guest account, then ask for commit rights to a given project.

Alpha

A port (formerly a release architecture and still available via debports) using the Linux kernel on (Compaq/Digital) Alpha hardware

AM

See Application Manager

Amd64

A port (and release architecture in squeeze) using the Linux kernel on 64bit PCs - technically x86-64 or AMD64 or Intel64, nontechnically most new consumer PCs

ANAIS

Short for "Architecture Not Allowed In Source"; used in bug reports for package removal, usually indicating that the number of architectures for which the package is to be built has been reduced

Applicant

A person requesting membership in the Debian project; prospective Debian developer.

Application Manager (AM)

A Debian member who is assigned to an applicant to collect the information needed by the Debian account managers to decide about an application. One application manager can be assigned to more than one applicant.

APT

Debian's Advanced Package Tool (or perhaps Advanced Packaging Tool - neither is "official"), a library that handles fetching the list of packages, resolving package dependencies, etc. It then uses dpkg to perform the actual package installation, removal, etc. The package apt provides the commandline tools apt-get and apt-cache, but other APT front-ends exist such as aptitude and synaptic.

Architecture
The type of system a piece of software is built for:

Archive
A set of files:

Area

The term used in Debian Policy for the main, contrib, and non-free divisions of the repositories (also known as components)

Arm

A port (superseded by armel and no longer maintained) using the Linux kernel on ARM/StrongARM hardware, a CPU type originally created for the Acorn Archimedes

Armel

A port (and release architecture in squeeze) using the Linux kernel on little-endian ARM/StrongARM chips, now common in embedded/mobile devices

Armhf

A (work-in-progress) port (not yet a release architecture but available via debports) using the Linux kernel on newer ("hard-float") armel-style hardware with an FPU

Avr32

A (work-in-progress) port (not yet a release architecture but available via debports but ) using the Linux kernel on Atmel's 32-bit RISC architecture

B

Backports

Backports are versions of packages from testing and unstable that have been rebuilt to be able to install and run on the stable distribution; especially those hosted on backports.debian.org

Base system

Binary packages with priority required or important; a minimalist set of packages installed before everything else on a new system. Designed to provide just the things you'd be surprised to find missing on a usable UNIX system. Not to be confused with essential, which is much smaller.

BD-Uninstallable

A wanna-build state

Binary
Several potentially confusing (but not Debian-specific) meanings:

Binary package

An installable .deb file as opposed to the source package it's built from. The idea is that this is the "binary" compiled in the package building process (regardless of whether the output .deb contains a binary executable, documentation, or indeed Linux kernel source code). See also Virtual package.

BinNMU

A binary(-package)-only Non-Maintainer Upload - see binNMU

Bo

The codename for Debian 1.3, release date: 1997

BoF

Short for "Birds of a Feather"; a common type of discussion session held at DebConf

BSP

Short for "Bug Squashing Party"; a get-together of Debian enthusiasts (either virtual or In Real Life) for the purpose of fixing as many bugs as possible.

BTS

Short for "Bug Tracking System"

BTS-link

A system for synchronizing bug status in the Debian BTS with external bug tracking systems like Bugzilla. See this mail.

Building

Build-essential

The only package that's literally essential for building a Debian binary package is make (because Policy mandates the use of a Makefile), but the "build-essential" toolkit is a convenient short-cut: a standard set of packages defined to be required for all "normal" Debian packaging work, which can therefore be omitted from lists of build dependencies as obvious, just as essential packages are omitted from install-time dependencies.

Buzz

The codename for Debian 1.1, release date: 1996

BYHAND

The queue on ftp-master (alongside NEW) for uploads that need special manual handling, such as D-I images

C

CDBS

Short for "Common Debian Build System" (provided by cdbs)

Component

The term used in sources.list(5) for the main, contrib, and non-free archive areas

Conffile

A technical term defined in Policy; a file declared in a binary package's conffiles file is treated specially by dpkg to ensure that local modifications are not blindly overwritten by a package upgrade or deleted by a remove. Conffiles are (always?) stored in /etc, and are often conventional global configuration files but may also be initscripts, cronjobs, or similar.

Configuration file

Any file affecting the operation of a program, or providing site- or host-specific information, or otherwise customizing a program's behavior. May or may not be system-wide, or in an intelligible line-oriented text format, or marked as a conffile. Personal configuration files are traditionally stored as dotfiles in the home directory (see also rc-file).

Contrib
Additional, external software, in either of two senses:

Control file

As defined in Debian Policy:

  • The control file included in the debian directory of each source package contains dependency information required to build the package, and has separate stanzas containing further information for each binary-package

  • The control file included in the DEBIAN directory of each binary .deb (formed from the corresponding stanza in the source control file) contains dependency information required to install the package, plus the package description etc.

  • Any "control file"; that is, any file with the same multi-field syntax as the above - for instance, .dsc files are also counted as control files.

  • Custom Debian Distributions (CDD)

    The old name for subsets of Debian configured to support a particular target group out-of-the-box. Now known as Debian Pure Blends

    Critical
    Has two related Debian-specific meanings:

    Dak

    (Short for "Debian Archive Kit") The toolset used to manage the Debian repositories - see DakHowTo

    DAM

    Short for "Debian Account Manager"

    DD

    Short for "Debian Developer"

    DDP

    Short for the "Debian Documentation Project"

    Debian Developer (DD)

    A Debian Project member who has gone through the New Maintainer process and had their application accepted is called a Debian Developer.

    Debian Documentation Project

    A Debian sub-project covering various documentation issues. See webpages

    Debian Maintainer (DM)

    The status of a person who has passed the Debian Maintainer process. A Debian Maintainer is granted some rights to manage packages - in particular, the right to upload packages to the Debian archives. DMs aren't voting members of the Debian Project. See also Debian Developer, Alioth account. Not to be confused with the role of package Maintainer.

    Debian Member

    Full members of the Debian Project are referred to as Debian Developers. (ToDo: link to one coherent central explanation of the distinction between contributors, developers, maintainers, and uploaders, assuming there is one)

    Debian New Maintainer

    The process of becoming an official Debian Developer, or a person going through that process. See also Applicant.

    Debian Policy Manual

    DEHS

    Short for "Debian External Health Status"

    DEP

    Short for "Debian Enhancement Proposal", an RFC-like mechanism for planning efforts within the Debian Project

    Dependency-based boot

    A scheme, standard since squeeze, for organizing initscripts; "dependency-based" here means checking for things like networking and mounted file systems, not package installation relationships

    Dependency package

    An empty binary package that exists only for the sake of its declared dependencies on other packages, for instance to keep the current default version of gcc installed. See metapackage and transition-package for other common types.

    Dep-wait

    (Plus more rarely dep-wait-removed) A wanna-build state

    Derivative

    A term with various senses in finance, IP law, etc., but used in Debian for "child" distributions like Ubuntu; see the DerivativesFrontDesk

    DFSG

    Short for the "Debian Free Software Guidelines"; the rules of thumb included in the Debian Social Contract that can be used to judge whether material counts for the project's purposes as free. The string dfsg is often appended to package names and version-strings to indicate that the upstream version has been slightly modified to allow it to stay in main.

    D-I

    See Debian-Installer

    Distribution (distro, dist)

    Dist-upgrade

    DM

    See Debian Maintainer.

    DMUP

    Short for "Debian Machine Use Policies"; the Acceptable Use Policy for machines on the Debian network.

    Dotfoo

    For Debian-specific file extensions ("dotdeb" etc.) see . (dot)

    Downgrade

    An action not officially supported in Debian package management, though often possible (and where it isn't, a purge and re-install of the older version is often good enough).

    DPL

    Short for "Debian Project Leader"

    DPMT

    The Debian Python Modules Team, who work to improve the Python modules situation in Debian.

    DSA

    Short for either "Debian Security Advisory" or "Debian Systems Administrators"

    E

    Emergency

    The highest upload urgency level, synonymous with critical

    Essential

    A set of binary packages providing the absolute minimal functionality that must be available and usable on the system at all times. The idea is, if you're hit by a software or hardware failure halfway through an upgrade, leaving your package database in an inconsistent state, the essential packages should still work well enough to let you perform repair work.

    Etch

    The codename for Debian 4.0, release date: 2007

    Experimental

    The experimental repository is an incomplete distribution which developers can use to try out versions of software not intended to migrate to testing, and which users are warned not to install

    F

    Failed

    (Plus more rarely failed-removed) A wanna-build state

    FHS

    See Filesystem Hierarchy Standard.

    Filesystem Hierarchy Standard (FHS)

    the FilesystemHierarchyStandard defines the main directories and their contents in Linux and other Unix-like computer operating systems. The Debian Policy Manual only explains the exceptions applying to Debian.

    Free

    Compliant with the DFSG, and eligible to go in main

    Freeze

    The distribution development freeze is a period of time when the Debian Project is working to finalize and stabilize the content of the testing distribution (resolving Release Critical bugs, making final tweaks to Debian-Installer, deciding the contents of the CDs, etc.) before its release as the new stable. Debian's release policy is one of Release when Ready, so the length of the freeze period isn't fixed, but it tends to last something like six months.

    Front Desk

    The front desk members receive the initial applications, advocation messages, and final application reports. They are the point of contact if problems arise with an application.

    FTBFS

    Short for "Fails To Build From Source", a bugreport type produced by the build infrastructure when a binary package cannot be compiled.

    FTP master
    Several things, none of which necessarily involve the File Transfer Protocol:

    Full-upgrade

    An aptitude action more or less equivalent to (and formerly known as) a dist-upgrade.

    G

    General Resolution (GR)

    A decision ratified by a vote of Debian Developers, according to the procedure specified in the Debian Constitution

    Giveback

    In autobuilder jargon, packages are "taken" when an attempt is made to build them. Failures are often transient, fixed by simply trying again after a few days, so a "giveback" removes the "taken" flag from the package in the wanna-build database and puts it back into the normal needs-build queue.

    GR

    Short for "General Resolution"

    Grave

    An RC bug severity

    H

    Hamm

    The codename for Debian 2.0, release date: 1998

    I

    I386

    A "port" (or rather the original release architecture) using the Linux kernel on 32-bit PCs - the kind dominating the market through the 90s/00s and known variously as IBM-clone, x86, IA-32, or (W)Intel-compatible computers

    Ia64

    A port (and release architecture in squeeze) using the Linux kernel on Intel IA-64 AKA Itanium hardware, not to be confused with amd64

    IANADD

    Short for "I Am Not A Debian Developer" - a caveat in the tradition of IANAL

    IANAL

    Short for "I Am Not A Lawyer", often used on the debian-legal mailing list. Not Debian-specific; see Wikipedia's definition.

    ICE

    Short for "Internal Compiler Error"; used in bug reports for package removal, usually indicating that gcc does not yet fully support a new architecture

    Important
    Two Debian-specific meanings:

    Install

    Installed

    A wanna-build state

    IP
    Short for two things Debian needs to care about:

    ITA

    Short for "Intent to Adopt", used to track the status of orphaned packages (see WNPP) or documentation (see DDP).

    ITD

    Short for "Intent to Document", used by a documentation maintainer who intends to start writing a document. Using the WNPP system avoids duplicated effort; see DDP.

    Mass bug filing (MBF)

    Reporting a great number of bugs for the same problem. See the Debian Developer's Reference.

    MBF

    Short for "Mass Bug Filing".

    Mentee

    An occasionally seen word for "an individual being mentored". This term, like sponsee, may trigger responses of "that's not even a word" in some speakers (though alternatives like "mentoree" aren't much safer)

    Mentor

    An experienced Debian Member who takes responsibility for assisting a less experienced member or Applicant. Outside occasional efforts such as the Debian Women mentoring program, such relationships generally exist only on an informal and unofficial basis. Every Applicant has an advocate who may effectively act as a mentor; but despite the name of the debian-mentors mailing list, its primary function is to put new maintainers in touch with sponsors.

    Metapackage

    A dependency package designed to automatically pull in a family of packages; may function as a shortcut to simplify installation of a full desktop environment.

    MIA

    Short for "Missing In Action"; (a database tracking) Debian package maintainers who have abandoned their duties without retiring

    Minor

    A low bug severity

    Mips

    A port (and release architecture in squeeze) using the Linux kernel on big-endian SGI-style MIPS hardware

    Mipsel

    A port (and release architecture in squeeze) using the Linux kernel on the little-endian version of mips-style hardware

    N

    Native

    NBS

    Short for "Not Built from Source"; one of the criteria used to detect candidates for automated package removal, in this case removing a binary package that isn't built from any remaining source package. See ftpmaster_Removals.

    Needs-build

    A wanna-build state

    NEW

    The queue on ftp-master for packages uploaded for the first time, which need to be reviewed first - see REJECT. This includes renames, packages moving between areas, and source-packages that build new binary packages

    New Maintainer (NM)

    See Debian New Maintainer, Applicant, Debian Maintainer.

    NMU

    Short for "Non-Maintainer Upload"; a version of a package that wasn't uploaded by an official Maintainer, but rather by another Debian Developer. This typically occurs for security updates, Mass Bug Filings, and when the maintainer is on holiday - see Debian Developer's Reference.

    Non-free

    Not compliant with the DFSG; also, the archive area for software which is non-free but can be legally distributed by Debian.

    Non-US

    (Obsolete) A subdivision of the Debian archives needed for the slink/potato/woody releases to deal with US legal restrictions on the export of cryptographic software. Software such as GPG was hosted only on mirrors outside the USA.

    Normal

    The default bug severity

    Not-for-us

    A wanna-build state (not to be confused with non-us)

    NPOASR

    Short for "Never Part Of A Stable Release"; used in bug reports for package removal, implying that users won't see the package's absence as a regression

    NVIU

    Short for "Newer Version In Unstable"; one of the criteria used to detect candidates for automated package removal, in this case removing an experimental build as superseded by a more recent build already present in unstable. See ftpmaster_Removals.

    O

    O

    Short for the QA status "Orphaned"

    Obsolete

    Oldstable

    The distribution before the current stable release, which continues to receive some level of security support for a while (commonly a year) after it is superseded.

    Oldstable-proposed-updates

    The equivalent to stable-proposed-updates for oldstable

    Optional

    A package priority (the highest priority that's not installed by default)

    Origin

    In Release files and aptitude searches, the organization providing the repository - examples include Debian, Debian Backports, and Google, Inc.

    Orphan

    (Not to be confused with the following) In package management, a stray installed package with no reverse dependencies (such as a library for which the corresponding executable has been purged), which can be detected with tools such as deborphan. Such unwanted relics are now increasingly tracked by APT itself.

    Orphaned (O)

    (Not to be confused with the above) Used in package QA to indicate that a package has no maintainer, and is in need of adoption (see ITA and WNPP). If the package has a priority of standard or higher, the severity of the orphaning bug report should be set to important. The term is similarly used to indicate documentation that the author is declaring abandoned; see DDP.

    P

    Package

    Package Tracking System (PTS)

    The Package Tracking System lets you follow almost everything related to the life of a package, and is of interest for co-maintainers, QA workers, and advanced users

    PAPT

    Short for "Python Applications Packaging Team"

    Pending

    A BTS tag indicating that "a solution to this bug has been found and an upload will be made soon". In practice this may mean anything from "my regular sponsor is away for the weekend" to "it'll be folded into the scheduled major release in the new year"

    Pinning

    APT pinning is the name given to the use of apt_preferences(5) to define a modified system of package-management priorities. This makes it possible, for instance, to run an essentially stable system but specify particular packages for which newer candidates (e.g. backports) will automatically be preferred for installation.

    Piuparts

    Short for "Package Installation, UPgrading And Removal Testing Suite" - see piuparts.

    Point release

    Point releases are updated versions of a release, with incremented minor revision number (hence the name), incorporating all accumulated security fixes and grave bug-fixes. (Also, In Real Life, a type of minor avalanche.)

    Popcon

    The popcon score of a Debian package (see webpage) is meant to reflect its "popularity"; it is derived from data generated via the package popularity-contest, which periodically and anonymously submits statistics about which binary packages are installed on a system and whether they are used.

    Port

    Potato

    The codename for Debian 2.2, release date: 2000

    Powerpc

    A port (and release architecture in squeeze) using the Linux kernel on IBM/Motorola PowerPC hardware, meaning PowerMacs and other pre-Intel Macs

    Release

    see Debian Release

    Release Architecture

    An architecture supported as part of a stable release; ports qualify for this status when their autobuilders prove capable of "keeping up" and successfully building a sufficient proportion of the archive.

    Release Critical (RC)

    A bug that cannot be allowed in stable; a release cannot occur until all such bugs have been handled (by removal if necessary)

    Remove

    RequestTracker (RT)

    The issue-tracking system rt.debian.org, used by the Security and DSA teams (among others)

    Required

    The highest package priority; not to be confused with essential

    Rex

    The codename for Debian 1.2, release date: 1996

    RFA

    Short for "Request For Adoption"; a WNPP bug tag indicating that (due to lack of time, interest, or other resources) the current maintainer is asking for someone else to maintain this package. They will maintain it in the meantime, but perhaps not in the best possible way. Compare Orphaned.

    RFD

    Short for "Request For Documentation"; a DDP bug tag indicating that a manual or other documentation on a given topic is not yet available on the DDP and the reporting user requests that DDP members should give it priority when deciding which documents need to be written.

    RFH

    Short for "Request For Help"; a WNPP bug tag indicating that the current maintainer wants to continue to maintain this package, but needs some help to do this. This may be because the maintainer is overstretched in general, or because this package is particularly hard to maintain, or because bugs require specialist expertise to fix.

    RFP

    Short for "Request For Package"; a WNPP bug tag indicating that the reporter has found an interesting piece of software and would like someone else to maintain it for Debian.

    RM

    Used in subject lines of package removal requests. It might look like it's addressed to the Release Manager, but it's just a shouty version of rm.

    RoM

    Short for "Request of Maintainer"; used in bug reports for package removal, to indicate that it has been agreed with the package's own maintainer.

    Root
    A word with several technical uses (not Debian-specific), all deriving from the same metaphor of a node structure with a root and branches:

    ROP

    Short for "Request Of Porter"; used in bug reports for package removal, to indicate that the package is no longer built on a particular set of architectures

    RoQA

    Short for "Request of Quality Assurance"; used in bug reports for package removal, to indicate that it has been agreed with the QA team (usually because the package is orphaned)

    Short for "Software in the Public Interest, Inc.", the nonprofit foundation that manages resources and accepts donations on behalf of the Debian Project (which has no legal authority for doing so itself).

    Sponsee

    An occasionally seen word for "an individual being sponsored". This term, like mentee, may trigger responses of "that's not even a word" in some speakers (though alternatives like "sponsoree" aren't much safer)

    Sponsor

    A Debian Member with upload privileges who uses them on behalf of a package maintainer without such privileges. The sponsor is required to take responsibility for checking that there are no show-stopping quality issues, but is not recorded as the maintainer of the package. A sponsorship may be a one-off event, or the sponsor may also act informally as a mentor, helping to track down bugs and improve the packaging. See also advocate.

    Squeeze

    The codename for Debian 6.0, release date: 2011 (the current stable)

    Stable

    The stable suite is the distribution recommended for production use. Each stable release is "promoted" from testing status as the result of a cycle of development, debugging, and integration that usually lasts about two years.

    Stable-proposed-updates

    The suite where proposed fixes for major bugs in stable are queued for inclusion in a point release

    Stable-updates

    The StableUpdates suite (formerly implemented as volatile) is where proposed updates are queued for packages such as virus scanners that become uselessly out of date over the lifespan of a release.

    Standard

    A package priority (the lowest priority that's installed by default)

    Suite

    T

    Testing

    testing is the Debian distribution automatically generated out of packages migrating from unstable. The first step towards a new stable release is that testing undergoes a freeze.

    Testing-proposed-updates

    The equivalent to stable-proposed-updates for testing, used only in cases where the fixes need to bypass unstable

    Testing-security

    The testing-security suite is only roughly the testing equivalent of stable's security support, because it is run by a different ?team and because most new package versions fixing security bugs can simply go through unstable as usual

    TINLA

    Short for "This Is Not Legal Advice"; compare IANAL.

    Transition

    Often short for "library transition". A new version of a widely-used dependency hitting unstable can mean that large numbers of related packages need rebuilds or significant fixes before the whole set can migrate to testing.

    Transition package

    A dependency package designed to automatically replace one package with another, to smooth over a rename or similar migration (especially for users performing a dist-upgrade). Not connected with library transitions

    U

    Unstable

    The unstable distribution is where you can find the latest packages introduced into the Debian system.

    Update

    In APT (or front-ends), the process of refreshing the package-management system's information about what packages are available from the registered sources. Not to be confused with (or omitted before) an upgrade

    Upgrade

    Uploaded

    A wanna-build state

    Urgency

    A ranking system for uploads, indicating how important it is for the new version to reach the archives, and ranging from low to critical. See Debian Policy

    User
    A term with various potentially confusing senses (not Debian-specific):

    Username

    The string (corresponding to a numeric uid) that identifies a user to the system. Ambiguous when written as "user name" - root is a username; "Professor Sam Q. McRandom" is a user name

    Userspace

    (Of a process) Running outside the kernel; everything up to and including init is a user process in this sense. Ambiguous when written as "user space" (which may mean storage capacity available to users).

    V

    Virtual package

    A binary package that exists in name only, with no associated .deb file; used to organize systems of alternative dependencies (multiple binary packages can claim to "Provide" the same virtual package).

    Volatile

    The volatile suite is (roughly speaking) the old name for stable-updates

    W

    Wanna-build

    A tool forming part of the autobuild system that maintains a database of the build status of packages; see definitions

    Wheezy

    The codename for the current testing

    Wishlist

    The lowest bug severity (which can include things that aren't literally bugs at all)

    WNPP

    Short for "Work-Needing and Prospective Packages" - a pseudo-package used to collect reports of packages (and potential packages) in need of (new) maintainers in Debian. See ITP, O, RFA, RFH, RFP.

    Woody

    The codename for Debian 3.0, release date: 2002

    X

    X Strike Force (XSF)

    The team responsible for maintaining packages for the X Window System in Debian

    Y

    Z

    . (dot)

    .deb

    The file extension used for the standard installable binary package format used by Debian-based distributions.

    .dsc

    The file extension used for a Debian Source Control file, which is a particular format of control file forming a crucial component of a source-package

    .tdeb

    The file extension used for (proposed) separate translation packages - see Dep-4

    .udeb

    The file extension used for special binary packages containing Debian-Installer modules, not intended for installation on a normal system.
