pam_namespace_helper is a helper program for the pam_namespace module that sets up a private namespace
       for a session with polyinstantiated directories. The helper ensures that the namespace mount points exist
       before they are started to be used for the polyinstantiated directories. Mount points for home
       directories (lines with $HOME) are not created.

       pam_namespace_helper should be run by systemd at system startup. It should also be run by the
       administrator after defining the polyinstantiated directories but before enabling them.
