Okay, so after getting the kernel build issues worked around and
documented, I've gotten to part 4 "Checkpoint/restart a simple LXC
container" in the wiki.  It works!  A couple of minor issues with the

> $ lxc-execute --name foo --rcfile lxc-no-netns.conf -- /bin/sleep 1000

The full path to the rcfile needs to be supplied or lxc-execute errors
out.  Also, it seems that the above command needs its own terminal or it
should be run in the background.

> $ lxc-checkpoint --name foo --statefile /root/lxc-foo.ckpt

Is it intentional that this fails if /root/lxc-foo.ckpt already exists?
