Hello. I created and installed a dummy package that adds a symlink to
lualatex named dvilualatex in /bin. My use case for dvilualatex is
mostly to render latex previews in org mode, and when I run the command,
I get the following log:

Could I fix this by setting some environment variable? the file seems to
be present in texlive-latex-bin

Cheers.
