Well, by separating the freeze and checkpoint, we could do things like
snapshot the filesystem or would lxc_checkpoint make an external call
to do that ?

I will leave it as is for my next version and I am guessing it can be done
easily later ?

It can be (by setting the restart_args->freezer). I will leave it in
frozen for now. Maybe later we can add a command line option to let
user choose whether or not to leave it frozen
