On a seemingly fresh and perfect server you might see the following events logged in the
May 14 06:29:52 SERVER gdm-password]: pam_unix(gdm-password:auth): Couldn't open /etc/securetty: No such file or directory May 14 07:40:14 SERVER su: pam_unix(su:auth): Couldn't open /etc/securetty: No such file or directory
This is disturbing because it’s a fresh installation and everything else seems fine. Actually the system is working too, but log files are dirty with this message.
