Cheat Sheet: Configuring Serial Consoles on UNIX-like Systems

Quick and dirty way to configure serial consoles on UNIX-like Systems

Upstart based Ubuntu Systems

Tested on: Ubuntu 12.04

FreeBSD

Tested on: FreeBSD 6,7,8,9

Upstart based CentOS Systems

Tested on: CentOS 6.5

CentOS 6.5 and later Fedora based systems are really easy. The init scripts see if a serial console was configured in grub, and if so then they start one up when the OS boots.
