[tex-live] luaotfload tries to recompile an existing .luc file

[Christophe Jorssen]

Hello all,

Consider the following snippet:

\documentclass{article}
\usepackage{fontspec}
\begin{document}
Test
\end{document}

Compiling with lualatex, one can read in the log file:

(compiling luc:
/usr/local/texlive/2016/texmf-var/luatex-cache/generic/fonts/otl/lmroman10-regular.luc)
(load luc: /home/christophe/.texlive2016/texmf-var/luatex-cache/generic/fonts/otl/lmroman10-regular.luc))

Note that I installed TeXLive with root privilege.

So luaotfload tries first to compile a .luc file in a directory
without write permission and then load the existing one in an other
directory. I think it should load directly the existing .luc file.

As I don't know if it is a TeXlive or a luaotfload issue, I created a
tracker issue: https://github.com/lualatex/luaotfload/issues/375.

Note also that it was originally a question asked at tex.se:
http://tex.stackexchange.com/q/324564/8425

What do you think?

Thanks
