8 <title>Policy checklist for upgrading your packages</title>
12 <h1>Policy checklist for upgrading your packages</h1>
14 <h2>About the checklist</h2>
17 The checklist below has been created to simplify the upgrading process
18 of old packages. Note that this list is not `official'; it simply
19 gives an indication of what has changed and whether you are likely to
20 need to make changes to your package in light of this. If you have
21 doubts about a certain topic, if you need more details, or if you
22 think some other package does not comply with policy, please refer to
23 the Policy Manual itself. All of the changes from version 3.0.0
24 onwards indicate which section of the Policy Manual discusses the
25 issue: [3.4] means section 3.4. The section numbering changed when
26 the packaging manual was incorporated into policy; the section numbers
27 used below refer to the current version.
31 Here is how the check list works: Check which policy version your
32 package complies with currently (indicated in the "Standards-Version"
33 field of the source package). Then move upwards until the top and
34 check which of the items on the list might concern your package. Note
35 which sections of policy discuss this, and then check out the Policy
36 Manual for details. If you are upgrading from Policy version < 2.5.0,
37 it may be easier to check through the whole of policy instead of
38 picking your way through this list.
41 <h2>The checklist</h2>
46 * Add DEB_*_ARCH_CPU and DEB_*_ARCH_OS variables and recommend them
47 over GNU-style variables for that information. [4.9]
48 * Source package Architecture fields may contain "all" in combination
49 with other architectures. Clarify when "all" and "any" may be used
50 in different versions of the field. [5.6.8]
51 * The Debian archive software does not support uploading to multiple
52 distributions with one *.changes file. [5.6.14]
53 * Remove the permission for shared library packages to install
54 libraries in a non-standard location and modify ld.so.conf.
55 Packages should either be installed in a standard library directory
56 or packages using them should be built with RPATH. [10.2]
57 * Clarify installation directories for X programs and remove the
58 requirement to pre-depend on x11-common before installing into
59 /usr/include/X11 and /usr/lib/X11. [11.8.7]
60 * Remove the requirement that all characters in a manual page be
61 representable in the legacy encoding for that language. [12.1]
62 * Localized man pages should either be kept up-to-date with the
63 original version or warn that they're not up-to-date, either with
64 warning text or by showing missing or changed portions in the
65 original language. [12.1]
66 * The requirement for Perl modules to have a versioned Depend and
67 Build-Depend on perl >= 5.6.0-16 has been removed. [perl]
71 * The list of archive sections has been significantly expanded. See
72 http://lists.debian.org/debian-devel-announce/2009/03/msg00010.html
73 for the list of new sections and rules for how to categorize
75 * All packages must use debconf or equivalent for user prompting,
76 though essential packages or their dependencies may also fall
77 back on other methods. [3.9.1]
78 * The requirements for source package names are now explicitly
80 * Legacy XFree86 servers no longer get a special exception from the
81 FHS permitting /etc/X11/XF86Config-4. [9.1]
82 * Removed obsolete dependency requirements for packages that use
84 * Speedo fonts are now deprecated. The X backend was disabled
85 starting in lenny. [11.8.5]
86 * The GNU Free Documentation License version 1.3 is included in
87 common-licenses and should be referenced from there. [12.5]
91 * Care should be taken when adding functionality to essential and
92 such additions create an obligation to support that functionality
93 in essential forever unless significant work is done. [3.8]
94 * Changelog files must be encoded in UTF-8. [4.4]
95 * Tighten some format requirements for changelog files from a should
97 * Remove alternative changelog formats. Debian only supports one
98 changelog format for the Debian Archive. [4.4.1]
99 * New nocheck option for DEB_BUILD_OPTIONS indicating any build-time
100 test suite provided by the package should not be run. [4.9.1]
101 * All control files must be encoded in UTF-8. [5.1]
102 * debian/control allows comment lines starting with # with no
103 preceding whitespace. [5.2]
104 * Init scripts ending in .sh are not handled specially. They are not
105 sourced and are not guaranteed to be run by /bin/sh regardless of
106 the #! line. This brings Policy in line with the long-standing
107 behavior of the init system in Debian. [9.3]
108 * The start action of an init script must exit successfully and not
109 start the daemon again if it's already running. [9.3.2]
110 * /var/run and /var/lock may be mounted as temporary filesystems, and
111 init scripts must therefore create any necessary subdirectories
113 * /bin/sh scripts may assume that local can take multiple variable
114 arguments and supports assignment. [10.4]
115 * User mailboxes may be mode 600 and owned by the user rather than
116 mode 660, owned by user, and group mail. [11.6]
120 * The base section has been removed. contrib and non-free have been
121 removed from the section list; they are only categories. The base
122 system is now defined by priority. [2.4, 3.7]
123 * If dpkg-source -x doesn't provide the source that will be compiled,
124 a debian/rules patch target is recommended and should do whatever
125 else is necessary. [4.9]
126 * Standardized the format of DEB_BUILD_OPTIONS. Specified permitted
127 characters for tags, required that tags be whitespace-separated,
128 allowed packages to assume non-conflicting tags, and required
129 unknown flags be ignored. [4.9.1, 10.1]
130 * Added parallel=n to the standardized DEB_BUILD_OPTIONS tags,
131 indicating that a package should be built using up to n parallel
132 processes if the package supports it [4.9.1]
133 * Debian packages should not use convenience copies of code from other
134 packages unless the included package is explicitly intended to be
135 used that way. [4.13]
136 * If dpkg-source -x doesn't produce source ready for editing and
137 building with dpkg-buildpackage, packages should include a
138 debian/README.source file explaining how to generate the patched
139 source, add a new modification, and remove an existing
140 modification. This file may also be used to document packaging a
141 new upstream release and any other complexity of the Debian build
143 * The Uploaders field in debian/control may be wrapped. [5.6.3]
144 * An empty Debian revision is equivalent to a Debian revision of 0 in
145 a version number. [5.6.12]
146 * New Homepage field for upstream web sites. [5.6.23]
147 * The Breaks field declares that this package breaks another and
148 prevents installation of the breaking package unless the package
149 named in Breaks is deconfigured first. This field should not be
150 used until the dpkg in Debian stable supports it. [6.5, 6.6, 7]
151 * Clarify which files should go into a shared library package, into a
152 separate package, or into the -dev package. Suggest -tools instead
153 of -runtime for runtime support programs, since that naming is more
154 common in Debian. [8.1, 8.2]
155 * Files in /etc/cron.{hourly,daily,weekly,monthly} must be
156 configuration files (upgraded from should). Mention the hourly
158 * Packages providing /etc/X11/Xresources files need not conflict with
159 xbase (<< 3.3.2.3a-2), which is long-obsolete. [11.8.6]
160 * Manual pages in locale-specific directories should use either the
161 legacy encoding for that directory or UTF-8. Country names should
162 not be included in locale-specific manual page directories unless
163 indicating a significant difference in the language. All
164 characters in the manual page source should be representable in the
165 legacy encoding for a locale even if the man page is encoded in
167 * The Apache 2.0 license is now in common-licenses and should be
168 referenced rather than quoted in debian/copyright. [12.5]
169 * Packages in contrib and non-free should state in the copyright file
170 that the package is not part of Debian GNU/Linux and briefly
172 * Underscore (_) is allowed in debconf template names. [debconf]
176 * Package version numbers may contain tildes, which sort before
177 anything, even the end of a part. [5.6.12]
178 * Scripts may assume that /bin/sh supports local (at a basic level)
179 and that its test builtin (if any) supports -a and -o binary
180 logical operators. [10.4]
181 * The substitution variable ${binary:Version} should be used in place
182 of ${Source-Version} for dependencies between packages of the same
184 * Substantial reorganization and renaming of sections in the Debian
185 menu structure. Packages with menu entries should be reviewed to
186 see if the menu section has been renamed or if one of the new
187 sections would be more appropriate. [menu policy]
188 * The Source field in a .changes file may contain a version number
189 in parentheses. [5.6.1]
190 * The acceptable values for the Urgency field are low, medium, high,
191 critical, or emergency. [5.6.17]
192 * The shlibs file now allows an optional type field, indicating the
193 type of package for which the line is valid. The only currently
194 supported type is udeb, used with packages for the Debian
196 * Packages following the Debian Configuration management
197 specification must allow for translation of their messages by using
198 a gettext-based system such as po-debconf. [3.9.1]
199 * GFDL 1.2, GPL 3, and LGPL 3 are now in common-licenses and should
200 be referenced rather than quoted in debian/copyright. [12.5]
204 * Maintainer scripts must not be world writeable (up from a
205 should to a must) [6.1]
209 * Revert the cgi-lib change. [11.5]
213 * It is now possible to create shared libraries without
214 relocatable code (using -fPIC) in certain exceptional cases,
215 provided some procedures are followed, and for creating static
216 libraries with relocatable code (again, using -fPIC).
217 Discussion on debian-devel@lists.debian.org, getting a rough
218 consensus, and documenting it in README.Debian constitute most
219 of the process. [10.2]
220 * Packages should install any relevant files into the directories
221 /usr/include/X11/and /usr/lib/X11/, but if they do so, they
222 must pre-depend on x11-common (>= 1:7.0.0) [11.8.7]
226 * Packages shipping web server CGI files are expected to install
227 them in /usr/lib/cgi-lib/ directories. This location change
228 perhaps should be documented in NEWS [11.5]
229 * Web server packages should include a standard scriptAlias of
230 cgi-lib to /usr/lib/cgi-lib. [11.5]
231 * The version of FHS mandated by policy has been upped to
232 2.3. There should be no changes required for most packages,
233 though new top level directories /media, /srv, etc may be of
235 * All fields, apart from the Uploaders field, in the control file
236 are supposed to be a single logical line, which may be spread
237 over multiple physical lines (newline followed by space is
238 elided). However, any parser for the control file must allow
239 the Uploaders field to be spread over multiple physical lines
240 as well, to prepare for future changes. [ 5.1, 5.6.3 ]
241 * When scripts are installed into a directory in the system
242 PATH, the script name should not include an extension that
243 denotes the scripting language currently used to implement it.
245 * packages that invoke initscripts now must use invoke-rc.d to do
246 so since it also pays attention to run levels and other local
247 constraints. [ 9.3.3.2 ]
248 * We no longer use /usr/X11R6, since we have migrated away to
249 using Xorg paths. This means, for one thing, fonts live in
250 /usr/share/fonts/X11/ now, and /usr/X11R6 is gone.
251 [ 11.8.5.2, 11.8.7, etc]
255 * Recommend doc-base, and not menu, for registering package documentation.
256 * Run time support programs should live in subdirectories of
257 /usr/lib/ or /usr/share, and preferably the shared lib is named
258 the same as the package name (to avoid name collisions). [8.1]
259 * It is recommended that HTTP servers provide an alias /images to
260 allow packages to share image files with the web server [11.5]
264 + Prompting the user should be done using debconf. Non debconf
265 user prompts are now deprecated. [3.10.1]
269 - Restructuring causing shifts in section numbers and bumping of
270 the minor version number:
271 + Many packaging manual appendices that were integrated into policy
272 sections are now empty, and replaced with links to the Policy.
273 In particular, the appendices that included the list of control
274 fields were updated (new fields like Closes, Changed-By were added)
275 and the list of fields for each of control, .changes and .dsc files
276 is now in Policy, and they're marked mandatory, recommended or
277 optional based on the current practice and the behavior of the
278 deb-building tool-chain.
279 + Elimination of needlessly deep section levels, primarily in the
280 chapter Debian Archive, from which two new chapters were split out,
281 Binary packages and Source packages. What remained was reordered
282 properly, that is, some sect1s became sects etc.
283 + Several sections that were redundant, crufty or simply not designed
284 with any sort of vision, were rearranged according to the formula that
285 everything should be either in the same place or properly interlinked.
286 Some things remained split up between different chapters when they
287 talked about different aspects of files: their content, their syntax,
288 and their placement in the file system. In particular, see the new
289 sections about changelog files.
290 - Added Games/Simulation and Apps/Education to menu sub-policy
292 - Debian changelogs should be UTF-8 encoded. [C.2.2]
293 - shared libraries must be linked against all libraries that they
294 use symbols from in the same way that binaries are. [10.2]
295 - build-depends-indep need not be satisfied during clean
300 - packages providing the x-terminal-emulator virtual package
301 ought to ensure that they interpret the command line exactly
302 like xterm does. [11.8.3]
303 - Window managers compliant with the Window Manager Specification
304 Project may add 40 points for ranking in the alternatives [11.8.4]
308 - The section describing the Description: package field once again has
309 full details of the long description format. [3.4.2]
310 - Clarified that if a package has non-build-essential
311 build-dependencies, it should have them listed in the Build-Depends
312 and related fields (i.e. it's not merely optional). [4.2]
313 - When asked to restart a service that isn't already running,
314 the init script should start the service. [9.3.2]
315 - If the purpose of a package is to provide examples, then the
316 example files can be installed into <tt>/usr/share/doc/package</tt>
317 (rather than <tt>/usr/share/doc/package/examples</tt>). [12.6]
321 - It is no longer necessary to keep a log of changes to the upstream
322 sources in the copyright file. Instead, all such changes should be
323 documented in the changelog file. [12.7]
324 - <tt>Build-Depends</tt>, <tt>Build-Conflicts</tt>,
325 <tt>Build-Depends-Indep</tt>, and
326 <tt>Build-Conflicts-Indep</tt> must also be satisfied when the
327 clean target is called. [7.6]
328 - A new Apps/Science menu section is available [menu policy]
329 - debconf specification cleared up, various changes. [debconf
331 - It is no longer recommended to create symlinks from nonexistent
332 manual pages to undocumented(7). Missing manual pages for programs
333 are still a bug. [12.1]
337 - Packages no longer have to ask permission to call MAKEDEV in
338 postinst, merely notifying the user ought to be enough. [10.6]
339 - cryptographic software may now be included in the main
341 - task packages are no longer permitted; tasks are now created by a
342 special Tasks: field in the control file. [3.9]
343 - window managers that support netwm can now add 20 points when
344 they add themselves as an alternative for
345 /usr/bin/x-window-manager [11.8.4]
346 - The default compilation options have now changed, one should
347 provide debugging symbols in all cases, and optionally step
348 back optimization to -O0, depending on the DEB_BUILD_OPTIONS
349 environment variable. [10.1]
350 - Added mention of build-arch, build-indep, etc, in describing
351 the relationships with `Build-Depends', `Build-Conflicts',
352 `Build-Depends-Indep', and `Build-Conflicts-Indep'. May need to
353 review the new rules. [7.6, 4.8]
354 - Changed rules on how, and when, to invoke ldconfig in maintainer
355 scripts. Long rationale. [8]
356 - [Added the last note in 3.5.6 upgrading checklist item regarding
357 build rules, please see below]
361 - Emacs and TeX are no longer mandated by policy to be priority
362 standard packages [2.5]
363 - Programs that access docs need to do so via /usr/share/doc, and
364 not via /usr/doc/ as was the policy previously [11.5]
365 - Putting documentation in /usr/doc versus /usr/share/doc is now
366 a ``serious'' policy violation. [12.3]
367 - For web servers, one should not provide non-local access to the
368 /usr/share/doc hierarchy. If one can't provide access controls for
369 the http://localhost/doc/ directory, then it is preferred that one
370 ask permission to expose that information during the install. [11.5]
371 - There are new rules for build-indep/build-arch targets and
372 there is a new Build-Depend-Indep semantic. [7]
376 - Manpages should not rely on header information to have
377 alternative manpage names available; it should only use
378 symlinks or .so pages to do this [12.1]
379 - [Clarified note in 3.5.3.0 upgrading checklist regarding
380 examples and templates: this refers only to those examples used
381 by scripts; see section 10.7.3 for the whole story]
382 - Included a new section 10.9.1 describing the use of
383 dpkg-statoverride; this does not have the weight of policy
384 - Clarify Standards-Version: you don't need to rebuild your
385 packages just to change the Standards-Version!
386 - Plugins are no longer bound by all the rules of shared
388 - X Windows related things:
389 * Clarification of priority levels of X Window System related
391 * Rules for defining x-terminal-emulator improved [11.8.3]
392 * X Font policy rewritten: you must read this if you provide
393 fonts for the X Window System [11.8.5]
394 * Packages must not ship /usr/X11R6/lib/X11/app-defaults/ [11.8.6]
395 * X-related packages should usually use the regular FHS
396 locations; imake-using packages are exempted from this [11.8.7]
397 * OpenMotif linked binaries have the same rules as
398 OSF/Motif-linked ones [11.8.8]
402 - The system-wide mail directory is now /var/mail, no longer
403 /var/spool/mail. Any packages accessing the mail spool should
404 access it via /var/mail and include a suitable Depends field;
406 - The perl policy is now part of Debian policy proper. Perl
407 programs and modules should follow the current Perl policy
412 - Build-Depends arch syntax has been changed to be less
413 ambiguous. This should not affect any current packages [7.1]
414 - Examples and templates files for use by scripts should now live
415 in /usr/share/<package> or /usr/lib/<package>, with
416 symbolic links from /usr/share/doc/<package>/examples as
421 - X app-defaults directory has moved from
422 /usr/X11R6/lib/X11/app-defaults to /etc/X11/app-defaults [11.8.6]
426 - dpkg-shlibdeps now uses objdump, so shared libraries have to be
427 run through dpkg-shlibdeps as well as executables [8.1]
431 - Font packages for the X Window System must now declare a
432 dependency on xutils (>= 4.0.2) [11.8.5]
436 - Daemon startup scripts in /etc/init.d/ should not contain
437 modifiable parameters; these should be moved to a file in
438 /etc/default/; see [9.3.2] for details
439 - Files in /usr/share/doc must not be referenced by any
440 program. If such files are needed, they must be placed in
441 /usr/share/<package>/, and symbolic links created as required
442 in /usr/share/doc/<package>/ [12.3]
443 - Much of the packaging manual has now been imported into the
448 - A package of priority standard or higher may provide two
449 binaries, one compiled with support for the X Window System,
450 and the other without [11.8.1]
454 - By default executables should not be built with the debugging
455 option -g. Instead, it is recommended to support building the
456 package with debugging information optionally. Details in [10.1]
457 - Policy for packages where the upstream uses HTML changelog
458 files has been expanded. In short, a plain text changelog file
459 should always be generated for the upstream changes [12.8]
460 - Please note that the new release of the X window system (3.2)
461 shall probably need sweeping changes in policy
462 - Policy for packages providing the following X-based features
464 - X server (virtual package xserver) [11.8.2]
465 - X terminal emulator (virtual package x-terminal-emulator) [11.8.3]
466 - X window manager (virtual package x-window-manager, and
467 /usr/bin/x-window-manager alternative, with priority
468 calculation guidelines) [11.8.4]
469 - X fonts (this section has been written from scratch) [12.8.5]
470 - X application defaults [11.8.6]
471 - Policy for packages using the X Window System and FHS issues
472 has been clarified; see [11.8.7]
473 - No package may contain or make hard links to conffiles [11.7.3]
474 - Noted that newer dpkg versions do not require extreme care in
475 always creating the shared lib before the symlink, so the unpack
480 - Correction to semantics of architecture lists in Build-Depends
481 etc. Should not affect many packages [7.1]
485 - /usr/doc/<package> has to be a symlink pointing to
486 /usr/share/doc/<package>, to be maintained by postinst
487 and prerm scripts. Details are in [defunct]
488 - Introduced source dependencies (Build-Depends, etc.) [7.1, 7.6]
489 - /etc/rc.boot has been deprecated in favour of /etc/rcS.d.
490 (Packages should not be touching this directory, but should use
491 update-rc.d instead) [9.3.4]
492 - update-rc.d is now the *only* allowable way of accessing the
493 /etc/rc?.d/[SK]??* links. Any scripts which manipulate them
494 directly must be changed to use update-rc.d instead. (This is
495 because the file-rc package handles this information in an
496 incompatible way.) [9.3.3]
497 - Architecture-specific examples go in /usr/lib/<package>/examples
498 with symlinks from /usr/share/doc/<package>/examples/* or from
499 /usr/share/doc/<package>/examples itself [12.7]
500 - Updated FHS to a 2.1 draft; this reverts /var/state to
502 - Added MIME sub-policy document [9.7; mime-policy]
503 - VISUAL is allowed as a (higher priority) alternative to EDITOR [12.4]
504 - Modified liblockfile description, which affects
505 mailbox-accessing programs. Please see the policy document for
507 - If a package provides a changelog in HTML format, a text-only
508 version should also be included. (Such a version may be prepared
509 using lynx -dump -nolist.) [12.7]
510 - Description of how to handle version numbers based on dates
515 - Added the clarification that the .la files are essential for the
516 packages using libtool's libltdl library, in which case the
517 .la files must go in the run-time library package [10.2]
521 - Debian formally moves from the FSSTND to the FHS. This is a
522 major change, and the implications of this move are probably
524 - Only 3 digits of the Standards version need be included in
525 control files, though all four digits are still permitted. [4.1]
526 - The location of the GPL has changed to
527 /usr/share/common-licenses. This may require changing the
528 copyright files to point to the correct location of the GPL and
529 other major licenses [12.6]
530 - Packages that use libtool to create shared libraries must
531 include the .la files in the -dev packages [10.2]
532 - Use logrotate to rotate log files [10.8]
533 - section 5.8 has been rewritten (Programs for the X Window
535 - There is now an associated menu policy, in a separate document,
536 that carries the full weight of Debian policy [9.6; menu-policy]
537 - Programs which need to modify the files /var/run/utmp,
538 /var/log/wtmp and /var/log/lastlog must be installed setgid utmp [11.3]
541 ** Please note that section numbers below this point may not be up to date **
547 - Rearranged the manual to create a new Section 4, Files
548 + Section 3.3 ("Files") was moved to Section 4. The Sections
549 that were Section 4 and Section 5 were moved down to become
550 Section 5 and Section 6.
551 + What was Section 5.5 ("Log files") is now a subsection of the
552 new Section 4 ("Files"), becoming section 4.8, placed after
553 "Configuration files", moving the Section 4.8 ("Permissions
