Describe the bug

When I compile documents on nixos that use fira in lualatex with fontsetup the resulting documents have an unreadable font, see screenshot.

Steps To Reproduce

Steps to reproduce the behavior:

1. install nixos
2. create a file test.tex with content

\documentclass[]{article}
\usepackage[fira]{fontsetup}
\usepackage{lipsum}

\begin{document}
\lipsum
\end{document}

3. in the same directory as the file run nix-shell -p texliveFull --run 'lualatex test.tex'

Expected behavior

Have the correct (working) font.

Screenshots

Additional context

according to the log it uses the otf file shipped with texlive not the system wide fira font files (making it even stranger that it is broken).
