Net device, I think you're out of luck.  As for the hostname, if the
DHCP server actually sends a hostname, then you *can* leave it out of
install.cfg.

scripting sysinstall for pxeboot

[Christopher Cowart]

Hello-

I'm working on a project to netboot servers and perform a custom
installation of FreeBSD. I have pxeboot working with tftp, providing an
mfs image over the network.

sysinstall runs as init and attempts to follow my install.cfg. However,
when running my mediaSetFTP command, sysinstall errors with:
"The fxp0 device is not configured. You will need to do so in the
Networking configuration menu before proceeding."

However, I did set tryDHCP=YES. DHCP is working because 1) it just
netbooted from it; and 2) I tried with the installation CD. It doesn't
appear to be honoring my request that it try DHCP.

If I take sysinstall over manually, specifying the network information,
it works just fine.

I want the installation to work with DHCP. Does anyone have any
suggestions for debugging sysinstall in this way?

Thanks for your help,
