How do I set up a terminal log-in via USB port in Raspbian?

Question

How can I set up a log-in focused on a USB port so I can hook up a DB9-to-USB cable I already own up to log in using putty or minicom?

You will need to do 2 things to make this work:

Make the USB->serial cable always use the same device name when you connect it.
This article on noctis.de and this article on redhat magazine describe how you can do this.
Have the system run getty on that serial device.
Add a line like this to your /etc/inittab:
```
T1:23:respawn:/sbin/getty -L **{Device name from step one}** 115200 vt100
```

I have not done this with my RPi (or any Linux system) so I don't know how feasible this is.
