Thanks for the hint.
I just gave it a try as follows:
# start-stop-daemon  -S -x ./shell  --background

Unfortunately, it seems to have the same problem. By daemonizing, the
file descriptor stdin seems to be closed, so my test program loops
forever (which I was able to visualize with strace).

I may need to adapt my program to not use stdio, but rather other
filedescriptors. I suppose that they will not be impacted be
foreground/background issues?



Where do you start start-stop-daemon from? Directly from inittab or
from scripts in /etc/init.d?
How do you start other programs automatically?

Thanks,
Thomas
