As far as I can tell, SElinux isn't active. (libselinux is installed,  
but no other selinux package)

Yes, I didn't reinstate the original mtxrun script.

Probably.

That works:

texlua call_uname.lua

version #1 SMP Tue Jul 6 14:34:09 MSD 2010
release 2.6.18-028stab070.2
machine x86_64
nodename        aine.fiee.net
sysname Linux

Now I get the defunct uname again:

16002 15978 TS   21 15:41 ?        00:00:01  \_ /var/www/xxx/bin/ 
python /var/www/.../manage.py run_gunicorn -c /var/www/.../gunicorn- 
settings.py
16210 16002 TS   14 15:42 ?        00:00:08      \_ luatex -- 
interaction=batchmode --fmt=/var/opt/context/tex/texmf-cache/.../ 
formats/cont-en --lua=/var/opt/context/tex/texmf-cache/...
16212 16210 TS   17 15:42 ?        00:00:00          \_ [uname]  
<defunct>

(Meanwhile I switched from fcgi to gunicorn app server, but that  
didn't change anything WRT ConTeXt.)

I get no log output.


BTW: Thank you very much for your patience! I owe you! (And you, Taco,  
of course, and the others!)

Greetlings from Lake Constance!
