Re: Bug#929128: fonts-noto-cjk: not recognized by lualatex until mktexlsr

Hi All,

I am sorry. My recognition of the situation was wrong.

You are right. The way to reproduce this issue (not related to mktexlsr)
is
(1) Install texlive-full and fonts-noto-cjk from experimental.
(2) Run lualatex with the below LaTeX source and have error
"Package fontspec Error: The font "NotoSerifCJKJPLight" cannot be found."
(3) Installation of fonts-noto-cjk-extra fixes the issue even though
no font from
   fonts-noto-cjk-extra is used. XeLaTeX (with \usepackage[noto]{zxjafont}) and
   uplatex (with \usepackage[unicode,noto-otc]{pxchfon}) produce the desired
   PDF without fonts-noto-cjk-extra.

\documentclass[a4paper,12pt]{ltjsarticle}
\usepackage[noto-otf]{luatexja-preset}

\begin{document}
日本語
\end{document}

This seems a feature or a bug in TeXLive 2019 upstream, which should not have
been filed in BTS. So I close this issue.

Sorry again for bothering all of you....
