The default is neither "required" nor "optional". The firewall will
start even if the interface doesn't exist, provided that you haven't
used a configuration construct that requires the interface to be up in
order to start.

Is there a discussion somewhere of what

No -- but they are pretty obvious. Given the error message you are
seeing, something you are doing requires the IP address of eth0. Some
possibilities are:

- You are calling find_first_interface_address() in your params file
- You have used "&eth0" or "%eth0" in one of your files
- You have used "detect:" in a rule.
- You have entered "detect" in the ADDRESS column in the masq file
