I'm having trouble using LuaTeX on Guix. luaotfload doesn't seem to be able to find any fonts, whether system-wide or local (when used with fontspec). I get messages like:
luaotfload | db : Reload initiated (formats: otf,ttf,ttc); reason: Font "Cardo" not found. luaotfload | resolve : sequence of 3 lookups yielded nothing appropriate. ! Package fontspec Error: The font "Cardo" cannot be found. I don't have this issue on other distros, or on Guix when using XeTeX instead of LuaTeX. Is there some additional setup or configuration (or another package ?) that I need on Guix to get LuaTeX/luatofload to work properly ? (pathing issues of some sort ?)
