[Bug 1094872] Re: Installation information cause letter format instead of DIN A4

[Colin Watson]

I did some analysis of the cases where a country has multiple languages
available in /usr/share/i18n/SUPPORTED.  The summary of my conclusion is
that I do not think that this is in general amenable to automation, and
will require a table of special cases.

In some cases there seems to be to be a reasonably clear correct choice.
These include cases where there are special-purpose locales, "joke"
locales, cases where the country has minority language communities but
there is nevertheless a clear majority language that you might
reasonably guess a migrant to that country would adopt, and cases where
there's an official national language which you might therefore see on
road signs etc.  (Note that this decision will not come into effect if
the user's selected language has a locale in the selected country, so it
doesn't affect e.g. Spanish-speaking Mexicans living in the United
States.)

In some cases there appears to be no clear right choice, sometimes due
to geopolitical disputes:

In some cases I'm simply not sure:

Title:
  Installation information cause letter format instead of DIN A4

Bug description:
  Dear ladies and gentlemen,

  I switched to Debian unstable after problems with TeXLive installations introduce about Oneiric.
  As experienced Unix administrator (AIX and RedHat certified) I was astonished not to be able
  to solve the problem.
  After several attempts I found out that my choices given to the installer:
         English - Berlin timezone - German eliminate deadkeys
  yield without any reason to the assumption that the paper format is "letter".
  E.g. scientists in Germany allways use English language and Berlin time (i.e. the real place being Germay),
  which should clearly qualify to DIN A4 choice, so the choice for /etc/papersize (letter) should be altered
  to "a4" under these (and similar) selections.
  The behaviour is there as already stated since Oneiric - before it worked as expected -
  and is present in the latest flavour.
  I currently work under Xubuntu 12.10 but have several installations (including Ubuntu 12.10
  [which is really unstable and Unity still not configurable] and Debian Wheezy [testing,
  the latter working out of the box without changing /etc/papersize manually]).
  As this bug is quite clear I hope you can fix it before 13.04 - this bug is really mean as the
  real problem is hidden for the user and even when trying to change problems relvealed in
  TeXLive installation relying on the wrong set of papersize  the TeXLive scripts for that purpose
  are not working (Debian related).
  But this is _NOT_ a TeXLive problem - when in Germany (Berlin time) and setting English
  (i.e. /etc/default/locale  being: LANG="en_US.UTF-8"), papersize should be a4 and NOT letter.
  Otherwise one should ask for papersize seperately.
  If other data is needed (not think so - but anyway) please contact me:
     Jochen.M.Braun at gmx.de

  Many thanks in advance for your help!

  JMB

  P.S.: If I missed something - like an expert mode of the installer - please inform me.
     But as unexperienced users may have similar selections the problem should be fixed anyway.
