Package: tasksel=20
Priority: wishlist
Version: 2.24
Tags: patch

[ I was considering setting this as an 'important' bug as I consider this a
failure in the installation system and it has been reported too many times
but not acted upon. I have refrained myself but I feel this should be done=
for sarge ]

Note: This issue has also been brought up a number of times before, please=
see #270676, #246357, #272406 and #272586. I've opened up #301138 too which=
would fix this "properly" but I don't expect that to happend before the=20
release. The proposed patch below could, however, be safely included in=20

The deal here is that tasksel calls aptitude on new installations asking it=
to install all the 'Standard' packages but our 'standard' system is not=20
properly standard and will pull in packages that are really development=20
only and used by a minority of our users (see #301138). This has happened=
before and needs to be cut by ftp overrides, but until a consensus is=20
reached the d-i team could prevent this from happening by having tasksel=20
explicitly tell aptitude to _not_ install those packages. After all, a=20
development task should be introduced in tasksel (and has been asked for=20
already in #266702)

The attached patch fixes this issue with a temporary hack that works OK for=
sarge. I have tested the patch with simulated runs of all tasks currently=
provided and aptitude installs them just fine. The behaviour is as follows:

- IF tasksel is called on new installations and the user has selected a=20
task, then tasksel will ask aptitude to _not_ install any of the=20
development packages (compilers, headers, and such) of the Standard=20

- IF no tasks are selected in new installations, then users get the full
Standard: installation, including development packages.

On all other cases, the behaviour of tasksel remains the same.=20

Why would I like to see this on sarge and not postponed to etch:

- There have been a number of installation reports complaining about this
- Installing by default a compiler in an operating system is against all=20
security-wise recommendations, has been exploited by worms in the past and=
will be in the future.

Hopefully the patch is self-explanatory, feel free to ask for additional=20
information. I've tested it in a chroot jail will all of the current tasks=
and aptitude works OK for me in an updated sarge environment. I don't=20
expect this to fail in a chrooted sarge and I will test it if time permits.

   * Joey Hess
     - Add libtheora0 to desktop task so totem can play these files.
       (See #301262)
     - Add Bulgarian language and desktop language tasks contributed by
       Anton Zinoviev. Closes: #271178
     - Add tf2pt1, ttf2pt1-chinese and ttfprint to chinese-s an chinese-t to
       support printing of asian fonts. Closes: #305148
     - Remove language-env from chinese-t, since language-env does not support
       Chinese simplified yet. See #301496
     - Add scim-chewing and m17n-env to chinese-t-desktop, remove old cpanel
       and chinput input methods. Closes: #301496
     - Also remove language-env from chinese-s as it doesn't support that
       either, and remove obsolete cpanel from chinese-s-desktop too.
     - Add basic Arabic tasks. Closes: #282493
     - Add printconf to print-server for automatic printer setup. Closes: #293108
     - Add windbind to file-server since it's commonly used with samba.
       Closes: #292936
     - Look for desc files in /usr/local/share/tasksel too. Closes: #286170
     - Replace mozilla with firefox in desktop task. Closes: #282166
     - Add "force" test script contributed by Free Ekanayaka. This allows
       adding Test-force lines to tasks that force them to be installed,
       skipped, marked, or shown, without needing to write any code,
       and may be useful for CDDs. Closes: #275303
     - Allow later task descs to override earlier ones, useful if you
       want to blow away the standard Debian tasks, perhaps by using Test-force
       to hide them. Closes: #274936
     - Add a "new-install" test script (and export NEW_INSTALL for test
       scripts), to allow special control of tasks during new installs.
     - Add a new "standard" task which defaults to being marked for install
       on new installs and is otherwise hidden (because removing it makes
       little sense), and which causes all standard or above priority packages
       to be installed. Closes: #301273, #298702
     - Remove the -r, -i, and -s switches as unnecessary given the standard
     - Remove the -n switch since it was intended to be used with other removed
     - Make the lang test only do anything on new installs, to avoid tasksel
       looking at the LANG variable in everyday use.
     - Rename Packages field in input task files to Packages-list to allow
       really specifying a Packages value.
     - Deal better with ctrl-c cancel while in debconf.
   * KÄ?stutis BiliÅ«nas
     - Added openoffice.org-l10n-lt to lithuanian-desktop task.
     - Commented out kde-i18n-lt as the Lithuanian language currently is
       not supported by upstream.
     - Added aspell-lt to lithuanian task.
   * Christian Perrier
     - Fix errors in English descriptions of tasks:
       - web-server: "select packages"
       - *-desktop : "localises the desktop"
                     "that make it"
       - thai      : "for Thai speaking people"
       All translations unfuzzied
       Closes: #306081
   * Translations
     - All Bosnian translations completed by Safir Secerovic
     - All Malagasy translations added by Jaonary Rabarisoa
     - Fixes to Danish translations of language tasks by Claus Hindsgaul
     - All Vietnamese translations added by Clytie Siddall
     - Estonian translations of debconf templates by Siim Põder. Closes: #312464
     - Estonian translations of tasks by Siim Põder. Closes: #312463
     - Estonian translations of tasksel by Siim Põder. Closes: #312462
