    daemon: Create home directory for greeter user
    
    For OSTree, I'm trying to move components to a model where they
    automatically create whatever directories/files are needed in /var.
    This helps with upgrade/downgrade scenarios.
    
    In GDM's case, this is pretty easy to do because we start with full
    root privileges.
