In fact, it is not really a distro-provided package because Slackware 14.1 is not providing TexLive.
It is a package that I have built using a script from: http://slackbuilds.org/
Anyway, the problem is the same: If I need help with this package, I need to contact the packager, not this mailing-list.
However, I think my problem is not relative to the package itself as I am just wondering how TexLive is managing the path to find the texmf.cnf file.

And you have answered well, thank you:

$ kpsewhich --all texmf.cnf

$ kpsewhich --show-path=cnf

I see these interesting path:
- /usr/share/texmf-dist/web2c
- /usr/share/texmf/web2c

They are interesting for me because the prefix "/usr/share" is my favourite in the prefix proposed by the command and because the "/usr/share/texmf-dist/web2c" and "/usr/share/texmf/" directories already exist in my system.

Is there a reason to prefer using the "/usr/share/texmf/web2c/texmf.cnf" file instead of "/usr/share/texmf-dist/web2c/web2c/texmf.cnf"?
What happen if two "texmf.cnf" are available (one in each of these directories)?
Is there a way to have a local "texmf.cnf" file containing only my 3 added lines, and a global "texmf.cnf" file containing all the default lines in order to override only the part I want by editing my local file?
Maybe it should be better to have a hidden directory somewhere in my home directory to contain my "texmf.cnf" file?
