Linux-PAM supports -prefix everywhere, but it simply means "ignore nonexistent modules instead of warning". (Therefore it doesn't make sense on distros where pam_systemd is guaranteed to exist.)
However, the dash prefix never ignores errors returned by the module itself – that's what the 'optional' field is for.
