But simply replacing the root port of the child wouldn't be nice,
because usually programs want to access the root file system (for
data, whatever) to function properly.  Instead of doing that, there
could be an additional port to a special in-core filesystem associated
with processes, which want to use this per-process-filesystem-feature.
Then there could be function

  file_name_lookup_private (char *file...)

or something, which is implented via

  file_name_lookup_under (port_to_private_filesystem, file ...).

This way each process would have a private namespace available.
