[luatex] shell-escape broken?

[Laube, Ulrich]

​
Hi!

I have tried TL16 on different computers running Linux by now and one thing I noticed is the following:

\documentclass{minimal}
\begin{document}
\immediate\write18{uname -s > "foobar"}
\end{document}

With

pdflatex --shell-escape test.tex

the file foobar is created. With 

lualatex --shell-escape test.text

it is not. Can someone confirm this?

This seems to break (at least)
minted.sty (which tries to do \write18{which "pygmentize" && touch \jobname.aex})
and
ifplatform.sty.


Kind regards
Uli Laube
