>Description:
The Handbook section 11.3 "Core Configuration" has an example rc.conf file containing the following line:
network_interfaces="fxp0 lo0"

According to rc.conf(5) setting this to anything other than AUTO is deprecated:
"Set to the list of network interfaces to configure on this host or ``AUTO'' (the default) for all current interfaces.  Setting the network_interfaces variable to anything other than the default is deprecated."

The URL for the page of the handbook is:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/configtuning-core-configuration.html
>How-To-Repeat:

>Fix:
The line
network_interfaces="fxp0 lo0"
in the example should be removed.
