Comment:
I thought the dash in `-session` exactly means it's optional, just like for elogind or turnstile:

> If the type value from the list above is prepended with a - character the PAM library will not log to the system log if it is not possible to load the module because it is missing in the system. This can be useful especially for modules which are not always installed on the system and are not required for correct authentication and authorization of the login session.

Isn't this the right way?
