## NAME
       pam_namespace_helper - Helper binary that creates home directories

## SYNOPSIS
       **pam**___**namespace**___**helper**

## DESCRIPTION
       _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.
