Bug#824471: context: luatex finds an undefined control sequence in conf file

[Giacomo Boffi <giacomo.boffi@gmail.com>]

Package: context
Version: 2015.05.18.20150601-2
Severity: normal

Dear Maintainer,

I was installing context and apt-get printed

> Setting up context (2015.05.18.20150601-2) ...
> Running mtxrun --generate. This may take some time... done.
> Pregenerating ConTeXt MarkIV format. This may take some time...

It took a while, so I started another activity and, a few hours later,
when I came back to the terminal running apt-get, I still read

> Pregenerating ConTeXt MarkIV format. This may take some time...

some time is ok, a few hours is too much so I looked for the process
that was running forever and I found  it was

  luatex --ini --lua=/usr/share/texmf/tex/context/base/luat-cod.lua
/usr/share/texmf/tex/context/base/cont-en.mkiv dump

I killed it, and the installation continued and ended, with message

> W: Operation was interrupted before it could finish

I tried to run the command I've killed from the admin prompt

% luatex --ini --lua=/usr/share/texmf/tex/context/base/luat-cod.lua
/usr/share/texmf/tex/context/base/cont-en.mkiv dump
This is LuaTeX, Version 0.95.0 (TeX Live 2016/Debian)  (INITEX)
 system commands enabled.

! Undefined control sequence.
l.1020 \pdfoutput
                             \zerocount
?

and I had to kill also this process too...

Thank you in advance
                                 gb
