At this point, there will be a /var/lib/lxc/ltest/config which will
list lxc.rootfs = /var/lib/lxc/ltest/rootfs.  So these steps are not
quite what you want.

Perhaps you just want to

	sudo lxc-create -n ltest -t ubuntu
	sudo mkdir -p /data/lxc/ltest
	sudo mv /var/lib/lxc/ltest/rootfs /data/lxc/ltest/
	sudo sed -i 's/@/var/lib/lxc@/data/lxc@' /var/lib/lxc/ltest/config
	sudo lxc-start -n ltest
	[ check mac address ]
	sudo lxc-stop -n ltest
	[ change mac address in config ]
	sudo lxc-start -n ltest
	[ check mac address ]
