Indeed using TeXLive::TLPDB creates via

  our $hyphen = "$texdir/tex/generic/config/language.dat";
  our $hlocal = "/var/lib/texmf/config/language.dat";
  TeXLive::TLUtils::create_language_dat($tlpdb, $hyphen, $hlocal);

the same content as already in archive/hyphen-base.tar.xz ...
beside the first two lines (Generated by / $Id:).
Hacking TeXLive/TLPOBJ.pm to have a method root and skipping the
usermode in TeXLive/TLUtils.pm does only write out one entry.

Do I miss something here?
