Package: jadetex
Version: 3.13-4
Severity: normal
I experienced the following while upgrading to jadetex 3.13-4:
Preparing to replace jadetex 3.13-3 (using .../jadetex_3.13-4_all.deb) ...
Unpacking replacement jadetex ...
[...]
Setting up jadetex (3.13-4) ...
Configuration file `/etc/texmf/fmt.d/40jadetex.cnf'
==> File on system created by you or by a script.
==> File also in package provided by package maintainer.
What would you like to do about it ? Your options are:
Y or I : install the package maintainer's version
N or O : keep your currently-installed version
D : show the differences between the versions
Z : background this process to examine the situation
The default action is to keep your current version.

I shouldn't have been given a conffile prompt, as I've never customized
that file, and in fact didn't even know it existed.
Steve Langasek tells me this is because /etc/texmf/fmt.d/40jadetex.cnf used
to be a non-conffile configuration file (created by the package "manually"
rather than unpacked to the system), and therefore dpkg believes the local
admin had put the file there.
If there's a small set of existing ways for that file to look, you might be
able to enhance your preinst script to detect an already-installed stock
version and move it out of the way. Because the preinst and postinst
scripts can fail, I would do this transactionally, with a prepare/commit
(or prepare/rollback) approach.
I have had to do something very similar in xfree86, where I have *stopped*
making certain files conffiles. I therefore offer three shell functions
(attached) which you may want to adapt to your needs.
Please let me know if you need any explanations or assistance with this.
