12 <chapt> About the checklist
14 The checklist below has been created to simplify the upgrading process
15 of old packages. Note that this list is not "official"; it simply
16 gives an indication of what has changed and whether you are likely to
17 need to make changes to your package in light of this. If you have
18 doubts about a certain topic, if you need more details, or if you
19 think some other package does not comply with policy, please refer to
20 the Policy Manual itself. All of the changes from version 3.0.0
21 onwards indicate which section of the Policy Manual discusses the
22 issue: [3.4] means section 3.4. The section numbering changed when
23 the packaging manual was incorporated into policy; the section numbers
24 used below refer to the current version.
26 Here is how the check list works: Check which policy version your
27 package was checked against last (indicated in the "Standards-Version"
28 field of the source package). Then move upwards until the top and
29 check which of the items on the list might concern your package. Note
30 which sections of policy discuss this, and then check out the Policy
31 Manual for details. If you are upgrading from Policy version < 2.5.0,
32 it may be easier to check through the whole of policy instead of
33 picking your way through this list.
37 <sect> Version 3.8.5.0
43 <tag>5.6.8, 7.1, 11.1.1</tag>
44 <item>Architecture wildcards may be used in addition to specific
45 architectures in <file>debian/control</file> and <file>*.dsc</file>
46 Architecture fields, and in architecture restrictions in build
50 <item>Maintainer scripts are no longer guaranteed to run with a
51 controlling terminal and must be able to fall back to noninteractive
52 behavior (debconf handles this). Maintainer scripts may abort if there
53 is no controlling terminal and no reasonable default for a high-priority
54 question, but should avoid this if possible.
57 <item>The UID range of user accounts is extended to 1000-59999.
59 <tag>9.3.2, 10.4</tag>
60 <item><file>init.d</file> scripts are a possible exception from the
61 normal requirement to use <tt>set -e</tt> in each shell script.
64 <item><package>perl-base</package> now
65 provides <package>perlapi-<var>abiname</var></package> instead of a
66 package based solely on the Perl version. Perl packages must now depend
67 on <package>perlapi-$Config{debian_abi}</package>, falling back
68 on <tt>$Config{version}</tt> if <tt>$Config{debian_abi}</tt> is not set.
72 <sect> Version 3.8.4.0
79 <item> An FHS exception has been granted for multiarch libraries.
80 Permitting files to instead be installed to <file>/lib/triplet</file> and
81 <file>/usr/lib/triplet</file> directories.
84 <item>Explicitly state that packages may not contain named pipes and
85 should instead create them in postinst and remove them in prerm or postrm.
88 <item><file>/sys</file> and <file>/selinux</file> directories are explicitly
89 allowed as an exception to the FHS.
93 <sect> Version 3.8.3.0
99 <item>Add DEB_*_ARCH_CPU and DEB_*_ARCH_OS variables and
100 recommend them over GNU-style variables for that information.
103 <item>Source package Architecture fields may contain <em/all/ in
104 combination with other architectures. Clarify when <em/all/ and <em/any/
105 may be used in different versions of the field.
108 <item>The Debian archive software does not support uploading
109 to multiple distributions with one <file>*.changes</file> file.
112 <item>The Binary field may span multiple lines.
115 <item>Remove the permission for shared library packages to
116 install libraries in a non-standard location and modify <file/ld.so.conf/.
117 Packages should either be installed in a standard library directory
118 or packages using them should be built with RPATH.
121 <item>Clarify installation directories for X programs and
122 remove the requirement to pre-depend on x11-common before installing
123 into <file>/usr/include/X11</file> and <file>/usr/lib/X11</file>.
126 <item>Remove the requirement that all characters in a manual
127 page be representable in the legacy encoding for that language.
130 <item>Localized man pages should either be kept up-to-date with
131 the original version or warn that they're not up-to-date, either
132 with warning text or by showing missing or changed portions in the
136 <item>install-info is now handled via triggers so packages no
137 longer need to invoke it in maintainer scripts. Info documents
138 should now have directory sections and entries in the document.
139 Packages containing info documents should add a dependency to
140 support partial upgrades.
143 <item>The requirement for Perl modules to have a versioned
144 Depend and Build-Depend on <tt>perl >= 5.6.0-16</tt> has been removed.
148 <sect> Version 3.8.2.0
155 <item>The list of archive sections has been significantly expanded. See
156 <url id="http://lists.debian.org/debian-devel-announce/2009/03/msg00010.html"
157 name="this debian-devel-announce message">
158 for the list of new sections and rules for how to categorize
162 <item>All packages must use debconf or equivalent for user prompting,
163 though essential packages or their dependencies may also fall
164 back on other methods.
167 <item>The requirements for source package names are now explicitly
171 <item>Legacy XFree86 servers no longer get a special exception from the
172 FHS permitting <file>/etc/X11/XF86Config-4</file>.
175 <item>Removed obsolete dependency requirements for packages that use
176 <file>/var/mail</file>.
179 <item>Speedo fonts are now deprecated. The X backend was disabled
183 <item>The GNU Free Documentation License version 1.3 is included in
184 common-licenses and should be referenced from there.
188 <sect> Version 3.8.1.0
195 <item>Care should be taken when adding functionality to essential and
196 such additions create an obligation to support that functionality
197 in essential forever unless significant work is done.
200 <item>Changelog files must be encoded in UTF-8.
203 <item>Tighten some format requirements for changelog files from a should
207 <item>Remove alternative changelog formats. Debian only supports one
208 changelog format for the Debian Archive.
211 <item>New nocheck option for DEB_BUILD_OPTIONS indicating any build-time
212 test suite provided by the package should not be run.
215 <item>All control files must be encoded in UTF-8.
218 <item>debian/control allows comment lines starting with # with no
219 preceding whitespace.
222 <item>Init scripts ending in .sh are not handled specially. They are not
223 sourced and are not guaranteed to be run by <prgn>/bin/sh</prgn> regardless
224 of the #! line. This brings Policy in line with the long-standing
225 behavior of the init system in Debian.
228 <item>The start action of an init script must exit successfully and not
229 start the daemon again if it's already running.
232 <item><file>/var/run</file> and <file>/var/lock</file> may be mounted as
233 temporary filesystems, and init scripts must therefore create any necessary
234 subdirectories dynamically.
237 <item> <file>/bin/sh</file> scripts may assume that local can take multiple
238 variable arguments and supports assignment.
241 <item>User mailboxes may be mode 600 and owned by the user rather than
242 mode 660, owned by user, and group mail.
246 <sect> Version 3.8.0.0
253 <item>The base section has been removed. contrib and non-free have been
254 removed from the section list; they are only categories. The base
255 system is now defined by priority.
257 <item>If <prgn>dpkg-source -x</prgn> doesn't provide the source that will be
258 compiled, a debian/rules patch target is recommended and should do whatever
260 <tag>4.9.1, 10.1</tag>
261 <item>Standardized the format of DEB_BUILD_OPTIONS. Specified permitted
262 characters for tags, required that tags be whitespace-separated,
263 allowed packages to assume non-conflicting tags, and required
264 unknown flags be ignored.
266 <item>Added parallel=n to the standardized DEB_BUILD_OPTIONS tags,
267 indicating that a package should be built using up to n parallel
268 processes if the package supports it
270 <item>Debian packages should not use convenience copies of code from other
271 packages unless the included package is explicitly intended to be
274 <item>If dpkg-source -x doesn't produce source ready for editing and
275 building with dpkg-buildpackage, packages should include a
276 <file>debian/README.source</file> file explaining how to generate
277 the patched source, add a new modification, and remove an existing
278 modification. This file may also be used to document packaging a
279 new upstream release and any other complexity of the Debian build
282 <item>The Uploaders field in debian/control may be wrapped.
284 <item>An empty Debian revision is equivalent to a Debian revision of 0 in
287 <item>New Homepage field for upstream web sites.
288 <tag>6.5, 6.6, 7</tag>
289 <item>The Breaks field declares that this package breaks another and
290 prevents installation of the breaking package unless the package
291 named in Breaks is deconfigured first. This field should not be
292 used until the dpkg in Debian stable supports it.
294 <item>Clarify which files should go into a shared library package, into a
295 separate package, or into the -dev package. Suggest -tools instead
296 of -runtime for runtime support programs, since that naming is more
299 <item>Files in <file>/etc/cron.{hourly,daily,weekly,monthly}</file> must be
300 configuration files (upgraded from should). Mention the hourly
303 <item>Packages providing <file>/etc/X11/Xresources</file> files need not
304 conflict with <tt> xbase (<< 3.3.2.3a-2)</tt>, which is
307 <item>Manual pages in locale-specific directories should use either the
308 legacy encoding for that directory or UTF-8. Country names should
309 not be included in locale-specific manual page directories unless
310 indicating a significant difference in the language. All
311 characters in the manual page source should be representable in the
312 legacy encoding for a locale even if the man page is encoded in
315 <item>The Apache 2.0 license is now in common-licenses and should be
316 referenced rather than quoted in <file>debian/copyright</file>.
318 <item>Packages in contrib and non-free should state in the copyright file
319 that the package is not part of Debian GNU/Linux and briefly
322 <item>Underscore (_) is allowed in debconf template names.
325 <sect> Version 3.7.3.0
332 <item>Package version numbers may contain tildes, which sort before
333 anything, even the end of a part.
335 <item>Scripts may assume that <file>/bin/sh</file> supports local (at a basic
336 level) and that its test builtin (if any) supports -a and -o binary
339 <item>The substitution variable ${binary:Version} should be used in place
340 of ${Source-Version} for dependencies between packages of the same
342 <tag>menu policy</tag>
343 <item>Substantial reorganization and renaming of sections in the Debian
344 menu structure. Packages with menu entries should be reviewed to
345 see if the menu section has been renamed or if one of the new
346 sections would be more appropriate.
348 <item>The Source field in a .changes file may contain a version number
351 <item>The acceptable values for the Urgency field are low, medium, high,
352 critical, or emergency.
354 <item>The shlibs file now allows an optional type field, indicating the
355 type of package for which the line is valid. The only currently
356 supported type is udeb, used with packages for the Debian
359 <item>Packages following the Debian Configuration management
360 specification must allow for translation of their messages by using
361 a gettext-based system such as po-debconf.
363 <item>GFDL 1.2, GPL 3, and LGPL 3 are now in common-licenses and should
364 be referenced rather than quoted in debian/copyright.
367 <sect> Version 3.7.2.2
373 <tag>6.1</tag> <item>Maintainer scripts must not be world writeable (up from a
374 should to a must)</item>
377 <sect> Version 3.7.2.0
383 <tag>11.5</tag> <item>Revert the cgi-lib change. </item>
386 <sect> Version 3.7.1.0
393 <item>It is now possible to create shared libraries without
394 relocatable code (using -fPIC) in certain exceptional cases,
395 provided some procedures are followed, and for creating static
396 libraries with relocatable code (again, using -fPIC).
397 Discussion on debian-devel@lists.debian.org, getting a rough
398 consensus, and documenting it in README.Debian constitute most
401 <item>Packages should install any relevant files into the directories
402 <file>/usr/include/X11/</file> and <file>/usr/lib/X11/</file>, but if
403 they do so, they must pre-depend on <tt>x11-common (>= 1:7.0.0)</tt>
406 <sect> Version 3.7.0.0
413 <item>Packages shipping web server CGI files are expected to install
414 them in <file>/usr/lib/cgi-lib/</file> directories. This location change
415 perhaps should be documented in NEWS
417 <item>Web server packages should include a standard scriptAlias of
418 cgi-lib to <file>/usr/lib/cgi-lib</file>.
420 <item>The version of FHS mandated by policy has been upped to
421 2.3. There should be no changes required for most packages,
422 though new top level directories <file>/media</file>, <file>/srv</file>,
423 etc. may be of interest.
424 <tag>5.1, 5.6.3</tag>
425 <item>All fields, apart from the Uploaders field, in the control file
426 are supposed to be a single logical line, which may be spread
427 over multiple physical lines (newline followed by space is
428 elided). However, any parser for the control file must allow
429 the Uploaders field to be spread over multiple physical lines
430 as well, to prepare for future changes.
432 <item>When scripts are installed into a directory in the system
433 PATH, the script name should not include an extension that
434 denotes the scripting language currently used to implement it.
437 <item>packages that invoke initscripts now must use invoke-rc.d to do
438 so since it also pays attention to run levels and other local
440 <tag>11.8.5.2, 11.8.7, etc</tag>
441 <item>We no longer use <file>/usr/X11R6</file>, since we have
442 migrated away to using Xorg paths. This means, for one thing, fonts
443 live in <file>/usr/share/fonts/X11/</file> now, and <file>/usr/X11R6</file>
447 <sect> Version 3.6.2.0
454 <item>Recommend. doc-base, and not menu, for registering package documentation.
457 <item>Run time support programs should live in subdirectories of
458 <file>/usr/lib/</file> or <file>/usr/share</file>, and preferably the shared
459 lib is named the same as the package name (to avoid name collisions).
462 <item>It is recommended that HTTP servers provide an alias /images to
463 allow packages to share image files with the web server
467 <sect> Version 3.6.1.0
474 <item>Prompting the user should be done using debconf. Non debconf
475 user prompts are now deprecated.
485 <item>Restructuring causing shifts in section numbers and bumping of
486 the minor version number:
488 <item>Many packaging manual appendices that were integrated into policy
489 sections are now empty, and replaced with links to the Policy.
490 In particular, the appendices that included the list of control
491 fields were updated (new fields like Closes, Changed-By were added)
492 and the list of fields for each of control, .changes and .dsc files
493 is now in Policy, and they're marked mandatory, recommended or
494 optional based on the current practice and the behavior of the
495 deb-building tool-chain.
497 <item>Elimination of needlessly deep section levels, primarily in the
498 chapter Debian Archive, from which two new chapters were split out,
499 Binary packages and Source packages. What remained was reordered
500 properly, that is, some sects became sects etc.
502 <item>Several sections that were redundant, crufty or simply not designed
503 with any sort of vision, were rearranged according to the formula that
504 everything should be either in the same place or properly interlinked.
505 Some things remained split up between different chapters when they
506 talked about different aspects of files: their content, their syntax,
507 and their placement in the file system. In particular, see the new
508 sections about changelog files.
509 <tag>menu policy</tag>
510 <item>Added Games/Simulation and Apps/Education to menu
513 <item>Debian changelogs should be UTF-8 encoded.
515 <item>shared libraries must be linked against all libraries that they
516 use symbols from in the same way that binaries are.
518 <item>build-depends-indep need not be satisfied during clean
522 <sect> Version 3.5.10
529 <item>packages providing the x-terminal-emulator virtual package
530 ought to ensure that they interpret the command line exactly
533 <item>Window managers compliant with the Window Manager Specification
534 Project may add 40 points for ranking in the alternatives
537 <sect> Version 3.5.9.0
544 <item>The section describing the Description: package field once again has
545 full details of the long description format.
547 <item>Clarified that if a package has non-build-essential
548 build-dependencies, it should have them listed in the Build-Depends
549 and related fields (i.e. it's not merely optional).
551 <item>When asked to restart a service that isn't already running,
552 the init script should start the service.
554 <item>If the purpose of a package is to provide examples, then the
555 example files can be installed into <file>/usr/share/doc/package</file>
556 (rather than <file>/usr/share/doc/package/examples</file>).
559 <sect> Version 3.5.8.0
566 <item>It is no longer necessary to keep a log of changes to the upstream
567 sources in the copyright file. Instead, all such changes should be
568 documented in the changelog file.
570 <item><var/Build-Depends/, <var/Build-Conflicts/, <var/Build-Depends-Indep/,
571 and <var/Build-Conflicts-Indep/ must also be satisfied when the clean
573 <tag>menu policy</tag>
574 <item>A new Apps/Science menu section is available
575 <tag>debconf policy</tag>
576 <item>debconf specification cleared up, various changes.
578 <item>It is no longer recommended to create symlinks from nonexistent
579 manual pages to undocumented(7). Missing manual pages for programs
583 <sect> Version 3.5.7.0
590 <item>Packages no longer have to ask permission to call MAKEDEV in
591 postinst, merely notifying the user ought to be enough.
593 <item>cryptographic software may now be included in the main
596 <item>task packages are no longer permitted; tasks are now created by a
597 special Tasks: field in the control file.
599 <item>window managers that support netwm can now add 20 points when
600 they add themselves as an alternative for
601 <file>/usr/bin/x-window-manager</file>
603 <item>The default compilation options have now changed, one should
604 provide debugging symbols in all cases, and optionally step
605 back optimization to -O0, depending on the DEB_BUILD_OPTIONS
606 environment variable.
608 <item>Added mention of build-arch, build-indep, etc, in describing
609 the relationships with `Build-Depends', `Build-Conflicts',
610 `Build-Depends-Indep', and `Build-Conflicts-Indep'. May need to
611 review the new rules.
613 <item>Changed rules on how, and when, to invoke ldconfig in maintainer
614 scripts. Long rationale.
618 Added the last note in 3.5.6 upgrading checklist item regarding build
619 rules, please see below
622 <sect> Version 3.5.6.0
629 <item>Emacs and TeX are no longer mandated by policy to be priority
632 <item>Programs that access docs need to do so via <file>/usr/share/doc</file>,
633 and not via <file>/usr/doc/</file> as was the policy previously
635 <item>Putting documentation in <file>/usr/doc</file> versus
636 <file>/usr/share/doc</file> is now a ``serious'' policy violation.
638 <item>For web servers, one should not provide non-local access to the
639 <file>/usr/share/doc</file> hierarchy. If one can't provide access
640 controls for the http://localhost/doc/ directory, then it is preferred
641 that one ask permission to expose that information during the install.
643 <item>There are new rules for build-indep/build-arch targets and
644 there is a new Build-Depend-Indep semantic.
647 <sect> Version 3.5.5.0
654 <item>Manpages should not rely on header information to have
655 alternative manpage names available; it should only use
656 symlinks or .so pages to do this
659 <item><em> Clarified note in 3.5.3.0 upgrading checklist regarding
660 examples and templates: this refers only to those examples used
661 by scripts; see section 10.7.3 for the whole story</em>
664 <item>Included a new section 10.9.1 describing the use of
665 dpkg-statoverride; this does not have the weight of policy
668 <item>Clarify Standards-Version: you don't need to rebuild your
669 packages just to change the Standards-Version!
672 <item>Plugins are no longer bound by all the rules of shared
675 <tag>X Windows related things:</tag>
678 <item>Clarification of priority levels of X Window System related
682 <item>Rules for defining x-terminal-emulator improved </item>
684 <item>X Font policy rewritten: you must read this if you provide
685 fonts for the X Window System
688 <item>Packages must not ship <file>/usr/X11R6/lib/X11/app-defaults/</file>
691 <item>X-related packages should usually use the regular FHS
692 locations; imake-using packages are exempted from this
695 <item>OpenMotif linked binaries have the same rules as
696 OSF/Motif-linked ones
701 <sect> Version 3.5.4.0
702 <p> Released Apr 2001.
706 <item>The system-wide mail directory is now /var/mail, no longer
707 /var/spool/mail. Any packages accessing the mail spool should
708 access it via /var/mail and include a suitable Depends field;
711 <tag>11.9; perl-policy</tag>
712 <item>The perl policy is now part of Debian policy
713 proper. Perl programs and modules should follow the current Perl
718 <sect> Version 3.5.3.0
719 <p> Released Apr 2001
723 <item>Build-Depends arch syntax has been changed to be less
724 ambiguous. This should not affect any current packages
727 <item>Examples and templates files for use by scripts should now live
728 in <file>/usr/share/<package></file> or
729 <file>/usr/lib/<package></file>, with symbolic links from
730 <file>/usr/share/doc/<package>/examples</file> as needed
734 <sect> Version 3.5.2.0
736 <p> Released Feb 2001.
740 <item>X app-defaults directory has moved from
741 <file>/usr/X11R6/lib/X11/app-defaults</file> to
742 <file>/etc/X11/app-defaults</file>
746 <sect> Version 3.5.1.0
748 <p> Released Feb 2001.
752 <item>dpkg-shlibdeps now uses objdump, so shared libraries have to be
753 run through dpkg-shlibdeps as well as executables
757 <sect> Version 3.5.0.0
759 <p> Released Jan 2001.
763 <item>Font packages for the X Window System must now declare a
764 dependency on xutils (>= 4.0.2)
768 <sect> Version 3.2.1.1
770 <p> Released Jan 2001.
774 <item>Daemon startup scripts in <file>/etc/init.d/</file> should not contain
775 modifiable parameters; these should be moved to a file in
776 <file>/etc/default/</file>
779 <item>Files in <file>/usr/share/doc</file> must not be referenced by any
780 program. If such files are needed, they must be placed in
781 <file>/usr/share/<package>/</file>, and symbolic links
782 created as required in <file>/usr/share/doc/<package>/</file>
785 <item>Much of the packaging manual has now been imported into the
790 <sect> Version 3.2.1.0
796 <item>A package of priority standard or higher may provide two
797 binaries, one compiled with support for the X Window System,
798 and the other without
802 <sect> Version 3.2.0.0
808 <item>By default executables should not be built with the debugging
809 option -g. Instead, it is recommended to support building the
810 package with debugging information optionally. Details in
813 <item>Policy for packages where the upstream uses HTML changelog
814 files has been expanded. In short, a plain text changelog file
815 should always be generated for the upstream changes
818 <item>Please note that the new release of the X window system (3.2)
819 shall probably need sweeping changes in policy
822 <item>Policy for packages providing the following X-based features
826 <item>X server (virtual package xserver) </item>
828 <item>X terminal emulator (virtual package x-terminal-emulator) </item>
830 <item>X window manager (virtual package x-window-manager, and
831 <file>/usr/bin/x-window-manager</file> alternative, with priority
832 calculation guidelines)
