[Pkg-shadow-devel] Bug#663200: Bug#628843: Bug#659878: cannot set terminal process group (-1): Inappropriate ioctl for device

[Nicolas François]

Hello,

I created a branch (su-C_tty) starting with the patch from Wolfgang Zarre
(comment 141 in #628843). Thanks!

It seems to be the only way to fix this issue, even if it means I have to
maintain something I'm not confident with.
 

There is one thing I don't understand (let's start with this one):
When I execute a command with su –c <command>, it does not react to
SIGTSTP (either from Ctrl-Z or kill -SIGTSTP). It works OK when I execute
a shell.

Is this behavior expected? What is the reason?

Thanks in advance,
