[luatex] Problem with package.searchers in TeXLive 2020

[Eduardo Ochs]

No, dednat6 runs fine on the luatex of TeXLive 2020.
The problem is really in the Lua code in:

  /usr/local/texlive/2020/texmf-dist/tex/luatex/lualibs/

As those files are in a directory that doesn't say "latex"
anywhere - they are from ConTeXt - I though that this
could be the right place to ask, but now I am with the
feeling that it is not... =/

Where is the right place to discuss this?
Thanks in advance and sorry for the noise,
  Eduardo Ochs
