Indeed.

Information about the namespaces has to be saved at checkpoint time no
matter what, right? I guess I don't see any compelling reason to not
have the restart operation replicate the environment of the original
process. Otherwise we require userspace to read and interpret the
checkpoint stream and selectively feed the bits that the kernel is
responsible for to the kernel and process the rest itself (or have the
kernel ignore those records).
What's the argument for depending on userspace to set this up?
