Not for me. pdftex finds a file without extension, luatex not.

\openin0 makefile % makefile exist in the folder
  \ifeof0         % gives: luatex: don't exist; pdftex: exist
   don't exist
  \else
   exist
  \fi
\closein0

\input makefile %input by both engines

\bye

Imho luatex should find the file with \openin0 as it does with
\input.

yes, the luatex syntax has been extended here (which is fine). That
pdftex doesn't know this syntax is documented and not a problem.
