Does runc supports restoring a process in an existing namespace

Does runc support restoring a process in an existing namespace as CRIU does?

Yes.
First, a container is a process in the view of OS, and the process have independent namespace.
The code is shown blow,
(1) checkout a container
https://github.com/opencontainers/runc/blob/master/main.go#L112
(2)restore a container
https://github.com/opencontainers/runc/blob/master/main.go#L122
The runc call the interface of CRIU to do c/r for container.

I expect the reply can help you!

Thanks for the help.
Actually my question was, after i restore a container, is it possible to again restore another process/process tree into that existing restored container?
