This - a slight modification of your first suggestion - made
the luatex-0.95.0 binary in /usr/bin/ able to access texmf.cnf:

  cp -s /usr/share/texlive/texmf-dist/web2c/texmf.cnf \
        ~/usrc/luatex/0.95.0/build/

However, when I run

  fmtutil --byengine luatex

it says this, and aborts:

  fmtutil: running `luatex -ini   -jobname=dviluatex
-progname=dviluatex dviluatex.ini' ...
  (...)
  fmtutil: /home/edrx/.texmf-var/web2c/luatex/dviluatex.fmt installed.

It seems that I need to change luatex.ini, or one of the files it
"\input"s, to make it run something like the compatibility code in the
section "2.1.7 The backend primitives \pdf *" of the manual, because
recent luatexes have fewer "\pdf*" primitives that the luatex in
Debian...

Is there a standard way to do that? Where can I find the ".ini"s for
recent luatexes?
