Hi,
I can't seem to make ConTeXt work with system fonts. Let's take this simple example :
---------------------------------------------------------------------
\usemodule[simplefonts][size=12pt]
\setmainfont[liberationsans]
\starttext
Test text
\stoptext
---------------------------------------------------------------------
It won't compile :
---------------------------------------------------------------------
$ context aa.tex
mtx-context | run 1: luatex --fmt="/opt/context/tex/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/formats/luatex/cont-en" --jobname="aa" --lua="/opt/context/tex/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/formats/luatex/cont-en.lui" --no-parse-first-line --c:currentrun=1 --c:fulljobname="./aa" --c:input="./aa" --c:kindofrun=1 --c:maxnofruns=9 "cont-yes.mkiv"
This is LuaTeX, Version beta-0.81.0 (TeX Live 2016/dev) (rev 5350)

!LuaTeX error: cannot find OpenType font file for reading ()
==> Fatal error occurred, no output PDF file produced!
mtx-context | fatal error: return code: 1
---------------------------------------------------------------------
If I understand correctly, it fails on `defining > source file 'LiberationSans-Regular.ttf' is not found`. Yet said file is found by `mtx-run` (and has read access for all) :
---------------------------------------------------------------------
$ mtxrun --script fonts --list --all --pattern=Liberation
