Hello,

This is my first time trying out TeX on Guix, but ran into a problem trying to run lualatex on core-updates-frozen. Since I wasn't sure what I needed, I tried the huge full texlive package in case that solved the problem I was seeing. It did not.

Running lualatex on anything gives the output

This is LuaTeX, Version 1.13.0 (TeX Live 2021/GNU Guix)
 restricted system commands enabled.

kpathsea: Running mktexfmt lualatex.fmt
/gnu/store/cpflshy9z2yzd8dybm0j9a7i0bscpxa2-texlive-bin-20210325/share/texmf-dist/scripts/texlive/fmtutil.pl: Unexpected non-option argument(s): lualatex.fmt
Try "fmtutil --help" for more information.
I can't find the format file `lualatex.fmt'!

xelatex on the same file and environment worked fine. After some digging, I could get the lualatex.fmt file by installing texlive-tex-ini-files and running

lualatex -ini /gnu/store/skznnf2n2f4dwg44gm8bvcn78157z69p-texlive-tex-ini-files-59745/share/texmf-dist/tex/generic/tex-ini-files/lualatex.ini

With this lualatex.fmt file present, lualatex runs and produces the correct output. I'm guessing this is not the expected procedure, though I haven't been able to test on master to compare yet. I wasn't sure if I missed a texlive- package, but xelatex working as is makes me think not.

Hello,

Applied, thanks!

I don’t fully understand the issue but it looks like a reasonable and
non-intrusive fix.
