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}
