Yes, the intention is to integrate criu support into libcontainer next
(which should maybe solve the "detached after restore" issue) and then
finally add hooks to docker (so that you can use "docker dump" and
"docker restore"). At that point, we can probably obsolete this
script.

But while we worked on that, we can share this script that we have
been using to test it internally, so that we can make it easier for
others to try it as well :-)

If you think scripts/ is not the best location for this script, maybe
contrib/ would be good?

Cheers,
Filipe
