Surprisingly, this worked on my totally broken Arch Linux so far … I get 
no error messages, seems to be fine.

But this does not work, the .ini files are not found:

[130] arno at tiger> fmtutil --byengine luatex

fmtutil: running `luatex -ini   -jobname=dvilualatex 
-progname=dvilualatex dvilualatex.ini' ...
This is LuaTeX, Version beta-0.77.0-2013051112 (rev 4635)  (INITEX)
! I can't find file `dvilualatex.ini'.
<*> dvilualatex.ini

Please type another input file name:
! Emergency stop.
<*> dvilualatex.ini

This comes for all luatex-based formats. The .ini files and bins are 
located at


Is this a problem? Everything is owned by arno, not by root. Calling 
luatex reports v0.77, so it is found correctly.

Not related to the original problem, but something definitely is wrong 
here …
