So you make this useful for your cases by only using this with
application containers - created using lxc-execute, or, more precisely,
using lxc-init as the container's init.  So a container running a stock
distro can't be checkpointed.

Is this just to keep the patch simple for now, or is there some reason
to keep this limitation in place?
