Because of this paragraph from the TeX Policy Draft: ,---- 4.1 Configuration files | In a TeX system, in principle every TeX input file can be changed to | change the behavior of the system, and thus be regarded as a | configuration file. To prevent inflation of configuration files, | packages should not install any TeX input files as conffiles or | configuration files.

If nothing, why is there a debconf notice? We expected that /etc/texmf/web2c/mktex.cnf will never exist on a system unless the local admin has deliberately created it. So this debconf message is targetted at people who already now how to change the TeX system by placing files in appropriate directories below /etc/texmf, and thus also how to deal with the situation. Well, it seems there are other reasons why this file can exist. Without exactly looking at the code, one place that we forgot comes to my mind: The texconfig-sys utility. If this is used to change the system configuration, it will create files in TEXMFSYSCONFIG. So far for the general reasons, so far no conclusion. What's the content of the file on your system? Do you remember having made any changes to the TeX system, maybe with the texconfig utility? Regards, Frank -- Frank Küster Single Molecule Spectroscopy, Protein Folding @ Inst. f. Biochemie, Univ.
