[lxc-devel] Session Leader

[riya khanna]

criu dump --root /usr/local/lib/lxc/rootfs/root --evasive-devices \
--tcp-established --ext-mount-map /dev:dev --file-locks -n net -n mnt \
-n ipc -n pid -vvv -D data -o dump.log -t 74

I don't have dump.log for that run, but if you want I can rerun and
send you dump.log as well.
