I think I've got the basic idea at this point. Below is the solution I have come up with (after installing
openssh-3.8p1-chroot.tar.gz). There is still some glitch somewhere along the line but once I nail it
down I'll repost:
--------------------------------------------------------------------
useradd -s /bin/bash -d /home/chroot/./testssh/ -c "ssh-test" testssh
chown testssh /home/chroot/ -R
chmod 777 /home/chroot/ -R
passwd testssh

cd /home/chroot

mkdir etc bin usr usr/bin lib lib/tls usr/kerberos usr/lib usr/kerberos/lib

grep /etc/passwd -e "^root" -e "^testssh" > etc/passwd
grep /etc/group -e "^root" -e "^testssh" > etc/group
