OH MY GOD!!! I have posted this problem before and saw many 'me too'
reponses and thought that this problem is everywhere. After your and
Kostik's posts and decided to make a clean test. Turned off jails
and all custom kernel sysctls. Entered shell and run this cript - it printed:
heck
done!
I have rerun all configs and started jails - still works. Then i remembered
that i have always run this script fro midnight commander.
Started mc
Pressed ENTER on this script and it got suspended.
Now i am lost, whose problem is this? su's or mc's? or both?
If i remove su from the script and run simply
system('echo heck');
from mc it work fine. With su it gets suspended.
