Bing, there's a way to support external bind mounts with criu plugins. You can
look at the criu/test/mounts/ext/ sources for an idea of how this can be done.
The test in question does exactly what we see -- it puts a mountpoint with an
external source directory into the dumpee mount namespace and then puts a plugin
to criu helping it to handle this.

If you need any help in adopting the example to your needs -- let us know on the
mailing list.

Thanks,
