== How to teach CRIU to dump them ==
+
+
By default CRIU doesn't dump such mountpoints, because there's no way CRIU will be able to restore it -- the root of these mounts is out of the scope of what CRIU dumped. In the logs you would see the message like
+
+
34:/bar doesn't have a proper root mount
+
+
which will mean, that the mountpoint /bar has inaccessible root.
