OK, I see. So during purging of tetex-base we must remove only the
files, which might have been created during postin. The following
patch might do this. The creation of these files is done during
postin of tetex-bin and they are removed during postin on tetex-bin,
so I don't know in the moment, why the entry for /etc/texmf exist
anyway (oh wait, language.dat is not removed during postrm of
tetex-bin). In postin of tetex-bin I found further:

  rm -f ${TEXMFC}* ${FMTCNF}*
  rm -rf ${TEXMFD}
  rm -rf ${FMTD}

in case of purge, with

TEXMFC=/etc/texmf/texmf.cnf
FMTCNF=/etc/texmf/fmtutil.cnf
TEXMFD=/etc/texmf/texmf.d
FMTD=/etc/texmf/fmt.d

which is IMHO the same policy violation. We should remove only the
generated files and the files* versions and then we're done. The last
two commands are surplus.
Who will ever remove /etc/texmf if it is found to be empty? dpkg?
Hope I didn't tell too much nonsense.
