For the archives.
Never received a reply. But I continued to work on scripting screen
to run multiple chroot filesystems.
Finally this created a screen in detached mode that was running a
chrooted filesystem.
screen -S $name -d -m chroot /usr/chroot/$name
This was only half of the problem, still needed to script some way to
stop the chroot running in a screen. Tried these different commands
screen -S $name -X exit
screen -p $name -X exit
screen -S $name -X shutdown now
They did not work.
Finally went the kill task method
screen_pid=`screen -ls | grep $name | cut -f 1 -d .`
/bin/kill ${screen_pid}
