- or simply try it as a wiki pagename!
Or you can add it yourself. If you can't define it yourself you can put ToDo instead, but always check the sites mentioned above - if it isn't Debian-specific, an existing definition elsewhere is likely to be more helpful.
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 (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.
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
- 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.
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.
- The type of system a piece of software is built for:
(Not Debian-specific) A general category of hardware (such as "486" or "little-endian"), or a variant of some piece of software tailored for this hardware; may specifically mean the category as determined by some particular tool, such as arch or dpkg-architecture
One of the platforms for which Debian packages are built, known by labels such as amd64 or mipsel, and also differentiated by the OS kernel used - the same hardware (not literally an Intel 386 processor) may dualboot i386 and kfreebsd-i386 architectures. See also port, release architecture
- A set of files:
- A set of files, such as a software repository
- 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.
A wanna-build state
- Several potentially confusing (but non-Debian-specific) meanings:
- Any non-textfile, such as a JPEG format image
Any ELF executable (often used generically to include shellscripts and other non-binary executables normally found in a bin directory)
The output of a build process - see binary package
- 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 sourcecode).
The codename for Debian 1.3, release date: 1997
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.
Short for "Bug Tracking System"
A wanna-build state
- (Non-Debian-specific) A piece of architecture in the non-jargon sense
The only package that's literally essential for a Debian package build 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.
The codename for Debian 1.1, release date: 1996
Short for "Common Debian Build System" (provided by cdbs)
A technical term defined in Policy; a file declared in a 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).
- Additional, external software, in either of two senses:
- In various project upstreams, a collection of extra software produced by third parties and included into a distribution "without warranty"
- 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
(Short for "Debian Archive Kit") The toolset used to manage the Debian repositories - see DakHowTo
See Debian Developer
Short for the "Debian Documentation Project"
- Two things distinguished by capitalization:
- Debian Account
- Debian Account Manager (DAM)
- Debian Contributor
- Debian Developer (DD)
- Debian Documentation Project
A Debian sub-project covering various documentation issues. See http://www.debian.org/doc/ddp
- Debian Installer (D-I)
- 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 archive. 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
- Debian Policy Manual
- The document that describes what packages should contain, how they should be configured, and generally how packages fit together to create a Debian system.
- Debian Project
- Debian Project Leader (DPL)
The official representative of the Debian Project to the outside world, with internal managerial and coordinatory duties; elected annually. See http://www.debian.org/devel/leader
- Debian Pure Blends
A subset of Debian that is configured to support a particular target group out-of-the-box. Debian Pure Blends were formerly known as Custom Debian Distributions (CDD).
- Debian Security Advisory (DSA)
- Debian System Administrators (DSA)
Short for "Debian External Health Status" (see DEHS).
- Dependency-based boot
- 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.
(Plus more rarely dep-wait-removed) A wanna-build state
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.
- Distribution (dist)
- (Not Debian-specific) The complete set of software from one upstream project, considered as a unit. MacTeX is a TeX distribution, for instance, whereas NetBSD is a full Operating System distribution. This is the sense in which Debian is "a distribution".
A suite within the Debian repositories capable of providing a fully functional OS on its own, unlike the supplementary ones such as "testing-security". This is the sense in which stable is "a distribution".
In Debian package management, the process of migrating a whole system from one release to the next (dist-upgrades skipping a release are not supported)
In apt specifically, an action that makes relatively aggressive (but intelligent) attempts to bring the system fully up to date, even if this requires some changes to the list of installed packages (that is, it may automatically install, remove, or replace packages). Compare plain upgrade, and aptitude's full-upgrade.
See Debian Maintainer.
Short for "Debian Machine Use Policies"; the documented Acceptable Use Policy for machines on the Debian network.
An action not officially supported in Debian package management, though often possible (and where it isn't, a purge and reinstallation of the older version is often good enough).
Short for "Debian Project Leader"
The Debian Python Modules Team, who work to improve the Python modules situation in Debian.
A set of 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.
The codename for Debian 4.0, release date: 2007
(Plus more rarely failed-removed) A wanna-build state
- 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.
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
- FTP master
- Several things, none of which necessarily involve the File Transfer Protocol
The ftp-master server, the primary copy of the Debian archive
The FTPMaster team that looks after this server, doing tasks such as checking the incoming queue for policy or licensing violations
- Senior members of this team also rank as "FTP Masters"
- General Resolution (GR)
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.
Short for "General Resolution"
The codename for Debian 2.0, release date: 1998
Short for "Internal Compiler Error"; used in bug reports for package removal, usually indicating that GCC does not yet fully support a new architecture
To set up an Operating System (e.g. with Debian-Installer), or otherwise introduce software onto a system. Examples include installing a bootable image to your boot-sector, a homebrew kernel in /boot, or a shellscript in /usr/local/sbin. The Debian system is designed to permit various forms of local installation performed outside the package database, but you have to keep track of them yourself.
In Debian package management, to put a binary package onto a system in a way that registers it with the package database. Note that the package management system sees package upgrades as a subcategory of installs.
In APT (or front-ends), a particular action. Note however that install and remove can each be used to perform the opposite function, if given an appropriate suffix (e.g.: apt-get install foo- bar- will remove packages foo and bar).
A wanna-build state
- Short for two things Debian needs to care about:
- Internet Protocol, the primary communications protocol on the Internet; also often used to mean "IP address"
- Intellectual Property, the intangible assets covered by copyright/licensing/patent/trademark law
Short for "Intent to Translate", used by a translator who intends to start translating a document. This like the above is a mechanism to prevent duplication of efforts; see DDP.
- Mass bug filing (MBF)
Reporting a great number of bugs for the same problem. See the Debian Developer's Reference.
Short for "Mass Bug Filing".
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.
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.
Short for "Missing In Action"; (a database tracking) Debian package maintainers who have abandoned their duties without retiring
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.
A wanna-build state
Short for "NonMaintainerUpload"; a version of a package that wasn't uploaded by an official Maintainer, but rather by another developer. This typically occurs for security updates, Mass Bug Filings, and when the maintainer is on holiday - see Debian Developer's Reference.
(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.
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
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.
In aptitude (e.g. aptitude search ?obsolete), any currently installed package which is not available (in any version) from any known archive. This usually means that the system has dist-upgraded to a new stable release that no longer contains that package.Transition packages don't register as obsolete in this sense.
Also used to refer to automatically installed packages that are no longer needed (such as orphan libraries) and would be candidates for autoremoval.
In Release files and aptitude searches, the organization providing the repository - examples include Debian, Debian Backports, and Google, Inc.
(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 needs to be adopted (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.
- (In Java, TeX, etc.) A unit of software with a single shared namespace
- Package Tracking System (PTS)
Short for "Python Applications Packaging Team"
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.
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.)
The popcon score of a Debian package (see http://popcon.debian.org/) 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.
- (Non-Debian-specific) A physical hardware interface
- (Non-Debian-specific) A TCP networking endpoint identified by port number
- (Non-Debian-specific) A platform that software has been converted to run on
The codename for Debian 2.2, release date: 2000
Short for "Package Tracking System"
Short for "Quality Assurance" - see qa.debian.org
- Has several easily confused meanings:
- Short for "Release Candidate", in version strings (v1.9~rc5 comes before v1.9)
Short for "Radio Controlled"; one of the few original Toy Story character names never to have been adopted as a Debian release codename (it was a little buggy)
In a filename such as ~/.bashrc, indicates a type of configuration-file - usually interpreted as short for "runtime configuration", but apparently inspired by the following
- In the MIT Compatible Time-Sharing System back in the sixties, "runcom files"
see Debian Release
The occasion of a new stable version of Debian being declared ready for production use;
- 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)
In Debian package management, to uninstall a package, especially in a fashion that leaves behind conffiles (thus if you remove and then reinstall a package you won't lose your custom setup). See purge
In APT (or front-ends), a particular action. Note however that install and remove can each be used to perform the opposite function, if given an appropriate suffix (e.g.: apt-get remove foo+ bar+ will install packages foo and bar).
- RequestTracker (RT)
The codename for Debian 1.2, release date: 1996
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.
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.
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.
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.
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.
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.
- A word with several (non-Debian-specific) technical uses, all deriving from the same metaphor of a node structure with a root and branches:
The root directory (/) is the top level directory of the file system hierarchy - the part of the "directory tree" that everything else connects to.
The root file system is the primary mountpoint everything else is attached to; it contains the root directory, plus various other essential directories such as /bin and /lib, and may or may not include others such as /var or /home.
- The root user (uid 0) is the so-called "superuser", with unlimited privileges - equivalent to the "Administrator" on some other operating systems. (This name might lead you to expect users to be arranged in some sort of organizational tree structure, but it just means that the superuser can modify the root directory.)
- The root window is the desktop background, the element of the graphical environment that all other windows are defined relative to. (Thus "root tile" as a synonym for "desktop wallpaper".)
- The root zone is the core of the DNS system, where the nameservers that are authoritative for Top Level Domains (the "root nameservers") live.
The directory /root is the home directory of the root user, housed on the root file system. Not to be confused with the root directory as defined above.
- Not forgetting its senses of "inverse exponent", or "gain illicit superuser access, either for malicious purposes or to bypass a proprietary OS", or (in AU/NZ slang) "have sex with"... and it doesn't help that for some it's homophonous with "route".
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
Short for "Request of Stable Release Manager"; used in bug reports for package removal, to indicate that it has been agreed with the powers that be
Short for "Request Tracker"
The codename for Debian 3.1, release date: 2005
- A notional subdivision of the Debian repositories into functional categories such as "admin", "kde", and "video"
Also sometimes used as a synonym for archive area
A ranking system for bugreports, indicating how important it is for it to be fixed, and ranging from wishlist to critical. See http://www.debian.org/Bugs/Developer#severities
- Not a cross between a shrub and a blintz.
Short for shared libraries - that is, dynamically loadable subroutines compiled into object files so that a single copy loaded into memory can be accessed by as many different processes as need it. Normally have the file extension .so, followed by interface-version numbers.
A special file defined in Debian Policy for tracking shared library dependencies
The codename for Debian 2.1, release date: 1999
A package origin defined by a line in sources.list
A bash builtin that executes commands from a file
Compilable code, the input of a build process - see source package
- Source package
A unit of upstream software (with a single build system), which may correspond to several separate binary packages within Debian;
The bundle of files (.dsc file, upstream tarball, etc) used as input to the package-building process.
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).
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.
The stable distribution is the release 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.
A set of closely integrated packages (often multiple source packages)
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
Short for "This Is Not Legal Advice"; compare IANAL.
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
unstable is the Debian distribution where you can find the latest packages introduced into the Debian system.
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
In Debian package management, the process of installing the newest versions of a set of binary packages (by default, all packages that have newer candidates available).
In apt specifically, the kind of upgrade that only fetches and installs new versions of packages, without changing the list of installed packages (so for instance a package whose new version has extra dependencies would be left unupgraded). Compare dist-upgrade, and aptitude's safe-upgrade.
A wanna-build state
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 Policy
- A term with various non-Debian-specific but potentially confusing senses:
- An actual human being currently logged into the system
- Any service recipient (including for instance remote processes accessing a web server)
- An account, which may belong to a user in the first sense or just be a "system" account
In chmod(1), the specific user (in the above sense) with ownership of a file
Any normal, unprivileged account (thus "as a user" versus "as root")
- Any normal, non-technical human user, likely also to be a user in the above sense
None of these have anything to do with the top-level /usr directory, short for Unix System Resources (or some say originally Unix Source Repository).
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
(Of a process) Running outside the kernel; everything up to and including things like udev is a user in this sense. Ambiguous when written as "user space" (which may mean storage capacity available to users).
- 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).
A tool forming part of the autobuild system that maintains a database of the build status of packages (see http://www.debian.org/devel/buildd/wanna-build-states for details)
The codename for the current testing
Short for "Work-Needing and Prospective Packages" - a pseudopackage used to collect reports of packages (and potential packages) in need of (new) maintainers in Debian; see http://www.debian.org/devel/wnpp/, ITP, O, RFA, RFH, RFP.
The codename for Debian 3.0, release date: 2002
- X Strike Force (XSF)
File extension used for the standard installable binary package format used by Debian-based distributions.
File extension used for (proposed) separate translation packages - see Dep-4
File extension used for special packages containing Debian-Installer modules, not intended for installation on a normal system.
