I don't want to submit a bug since the last time this was discussed it
degenerated into a flamewar and from the text I quote below it seems
it's an emotionally overloaded issue for you.
Installing tetex-bin brings up this:
[!] Configuring Tetex-bin
Now we can generate texmf.cnf, the central configuration file for
TeX system, automatically with update-texmf script. This is
necessary for other TeX related packages to update the contents of
But this overwrites the existing texmf.cnf so if you don't want it,
don't accept this. Then you should modify /etc/texmf/texmf.cnf
manually. But REMARK that you could fail to install some TeX
For many users, it is recommended to accept this, despite the
default was set contrary, because this is necessary to install many
other TeX related packages and, if you want, you can custmize
texmf.cnf freely only with modifying files in /etc/texmf/texmf.d/
and adding necessary file(s) there.
Use automatic generation of texmf.cnf with update-texmf?
So the gist of that text is: "debian packages can manage the
configuration file by themselves, it's a good idea if they do and
there's a chance something will break unless you really really know
what you are doing". Then why does it default to "no"? Along the same
line: why is this high priority question if, by the look of it, only a
handful of people would care? This is release-note worthy or handbook
worthy, but it's not really the kind of thing Average Joe wants to see
when installing Debian afresh, is it?
Small request: please run that text thru our English l10n team
 Which I did just last week... boy, is it confusing!
