I noticed that in runc we have "addCriuRestoreMount" and "addCriuDumpMount".

An example of how they are used is:
https://github.com/opencontainers/runc/commit/af4a5e708a943879c02f7941a1d2e7b845544c66

Perhaps we could extend the interface of runc to allow podman or
contianerd to pass external mounts via those two functions to CRIU?
