Hello,
I forgot to send a carbon copy to help-guix ML in my last answer, so
I include it here.

Actually, the problem is on the Guix side, and it will be solved in the
"tex-team" branch.
Meanwhile, the solution is to set OSFONTDIR environment variable to
'{$XDG_DATA_DIRS}'.
With it, the following "test.tex" document compiles correctly:
--8<---------------cut here---------------start------------->8---
\documentclass{article}
\usepackage{fontspec}
\setmainfont{Fantasque Sans Mono}
\begin{document}
Test \textbf{Test} \textit{Test}
\end{document}
--8<---------------cut here---------------end--------------->8---
in the following environment
guix shell --pure texlive-collection-latex texlive-fontspec fontconfig
font-fantasque-sans
with the following command
export OSFONTDIR='{$XDG_DATA_DIRS}'; lualatex test.tex
Thank you for the bug report!
