I believe that the TUI installer should use the same default approach as the gui installer (TUI default is DHCP whereas GUI is to specify the ip address).
Adding to our feature request list. Thanks for your report.
Rather, I think that the GUI should be changed to be like the TUI. That is, it defaults to DHCP. I think most people (at least in environments like corporate networks and cable modems) are using DHCP these days, so I think it makes sense to default to that. Implemented in CVS. Brock, please verify. You'll have to do a CD-ROM install to verify this.
