I have issues with my ISP where my ssh sessions die at random times, usually (but not always) when I'm away from the computer. So solution for Poudriere was to run it in the background and pipe stdout+stderr to a file in /tmp. Then a tail -f on that file and it's almost as good as running it in the foreground -- but with the advantage that if the connection goes I can just log back in and tail -f again. I also have a script that runs in another window with the output of "poudriere status -b" followed by "sleep 4" in a loop. That way I can just glance to that side of my monitor to see how things are going. -- Kevin P. Neal http://www.pobox.com/~kpn/ "Good grief, I've just noticed I've typed in a rant. Sorry chaps!"
