Interesting. As a XeTeX user, I wasn't even aware of that :-) So, you never need
to run fc-cache manually?

Basically, yes. But, as you may know, we're finally releasing the "restricted
shell-escape" feature in TL10. AFAIK, the list of authorised programs is not
fixed yet, but if it can include fc-list, then mkluatexfontsdb could be invoked
directly from LuaTeX (not using os.system(), but using it directly since it is
lua code).

Somehow unrelated: I just realised mkluatexfontsdb uses io.popen(). Last time I
checked, this function was not working on windows. Did anyone test luaotfload on
