I compiled successfully the following document (test-font.tex):
--8<---------------cut here---------------start------------->8---
\documentclass[11pt,a4paper]{amsart}
\usepackage{unicode-math}
\setmathfont{Asana Math}
\setmainfont{Droid Serif}
\begin{document}
\[(D_e\Phi_{\gamma(s)})^{-1}(\gamma'(s))=\varphi'(s)(D_e\Phi_{\alpha(\varphi(s))})^{-1}(\alpha'(\varphi(s)))\]
\end{document}
--8<---------------cut here---------------end--------------->8---
using the following command:
guix shell texlive-scheme-small texlive-collection-luatex texlive-droid
texlive-asana-math texlive-unicode-math -- lualatex test-font.tex
However, I don't think it takes into consideration the specified fonts.
In the same environment, `luaotfload-tool --help' reports
--8<---------------cut here---------------start------------->8---
The font database will be saved to
{/gnu/store/f1hdawmb5401cldyl6f27lvc3hvxbw8l-profile/share/texmf-dist/luatex-cache/generic/names/luaotfload-names.lua.gz
{/gnu/store/f1hdawmb5401cldyl6f27lvc3hvxbw8l-profile/share/texmf-dist/luatex-cache/generic/names/luaotfload-names.luc
-------------------------------------------------------------------------------
FONT CACHE
--cache=<directive> operate on font cache, where <directive> is
"show", "purge", or "erase"
The font cache will be written to
{/gnu/store/f1hdawmb5401cldyl6f27lvc3hvxbw8l-profile/share/texmf-dist/luatex-cache/generic/fonts/
--8<---------------cut here---------------end--------------->8---
This doesn't seem good as the store is not writable.
I read[¹] that "texmf.cnf" and "texmfcnf.lua" might be misconfigured. In
particular, `kpsewhich -var-value=TEXMFCACHE' reports a store location.
At the very least, I think TEXMFCACHE in "texmf.cnf" should be set to
$TEXMFVAR instead of $TEXMFSYSVAR;$TEXMFVAR as it is the case currently.
I'm not sure it will help, tho.
Regards,
