I was utterly wrong in blaming LuaTeX: it's purely a LaTeX problem. lualatexquotejobname.tex expands \jobname at every job, forcing TeX to prematurely choose a job name before the first input file has been read. This can be provoked in any engine and format:

$ tex '\input knuth \bye'
... Output written on knuth.dvi ...
$ tex -ini '\input plain \everyjob{\edef\x{\jobname}}\dump'
... Beginning to dump on file plain.fmt ...
$ tex '&plain' '\input knuth \bye'
... Output written on texput.dvi ...

This means lualatexquotejobname has to be removed from the format, or at least rewritten so that \jobname is never expanded at every job:

$ lualatex '\input sample2e '
... Output written on texput.pdf ...
$ touch lualatexquotejobname.tex
$ lualatex -ini lualatex.ini
... (./lualatexquotejobname.tex) ... Beginning to dump on file lualatex.fmt ...
$ luatex '&lualatex' '\input sample2e '
... Output written on sample2e.pdf ...
