By this do you mean the very idea of having CR support in the kernel?
Or our design of it in the kernel?  Let's go back to July 2008, at the
containers mini-summit, where it was unanimously agreed upon that the
kernel was the right place (Checkpoint/Resetart [CR] under
http://wiki.openvz.org/Containers/Mini-summit_2008_notes ), and that
we would start by supporting a single task with no resources.  Was that
whole discussion effectively misguided, in your opinion?  Or do you
feel that since the first steps outlined in that discussion we've
either "gone too far" or strayed in the subsequent design?
