Here's a little demo.  Please poke holes in it and tell me how to
really do this :-)

#!/bin/sh
sudo lxc-start-ephemeral -o test-container2 -d > log 2>&1
while ! grep "is running" log
do
    sleep 1
done
container=`awk '/is running/ {print $1}' log`
sudo chroot /var/lib/lxc/$container/rootfs touch /xyzzy
sudo chroot /var/lib/lxc/$container/rootfs ls -l /xyzzy
sudo lxc-stop --name $container
