Comment # 19 on bug 983636 from Dainius Masiliunas

I just got hit by this too.

>From what I can see, the issue is still there, as installing pam-config
overwrites config files provided by pam (which do include pam-systemd) with its
own ones (which do not include pam-systemd). systemd RPM scripts run pam-config
--add --systemd to readd it, but that is not very robust, apparently, since
otherwise I would not have been hit by this issue.

Why don't pam-config initial files include pam-systemd by default, when pam
itself does?
