Hi Hans,

Thanks for the link to the code. A quick install suggests that a 'hello 
world' is working nicely from ConTeXt. However, if I try what you might 
expect from me

     luametatex --ini latex.ltx

things go a bit wrong:

     This is LuaMetaTeX, Version 2.00.0  (INITEX)
     ! error:  (system): missing find_write_file callback

(I also notice there is no plain-like format for testing, or at least 
that just "luametatex" yields an error.)

Clearly things work for ConTeXt, so there must be some early Lua magic 
or similar required. Any thoughts? (I don't get a .log or any other output.)
