>Description:
I have installed a FreeBSD 3.3 machine, and it does not have
a localhost interface. As far as I can remember, I have done the network
configuration after installing bsd, and have played with it a little bit. 
However, I have not worked manually on the configuration files to
get this result.


There is also a second problem: when I enter the sysinstall menu, go to 
configuration/networking and select "interfaces", I get the following
question: "Running multi-user, assume that the network is already configured?"
When I answer yes, the sysinstall coredumps with a segmentation fault.
(when I answer no, everything seems to be ok and I can reconfigure the network interface - 
but after that the problems are still the same)

I have edited rc.conf and corrected (at least I think so) the 
contradictions in the rc.conf, but I still dont have a 
localhost interface, and sysinstall still crashes:
# This file now contains just the overrides from /etc/defaults/rc.conf

>How-To-Repeat:
I can reproduce the sysinstall crash on the machine. However, I cannot
remember what exactly I did to get a system without localhost.
