According to the comments in /etc/init/serial.conf you shouldn't have a /etc/init/ttyS0.conf or do anything to /etc/securetty. This is all handled automatically. You just add 'console=tty0 console=ttySX,YZ' to the kernel line in grub and that's it. I did it like this a couple of days ago on 6.5. Works as advertised for me but I have never used a serial console before. -Michael
