[lxc-users] CRIU + lxc container

[Serge Hallyn]

I haven't looked at the code yet, but since our tty is actually a
pts, do you need a different plugin than tty.c to checkpoint it?
I think you'll get more useful replies from the criu list.

I do want to get criu+lxc working soon-ish, but other things need
to get tidied up first.
