You do not have netenv configured yet. An unconfigured netenv package will
ask to do type in a network configuration at boot time. Once you have
configured a network connection you can bypass the netenv prompt by adding a
parameter add the boot prompt. Unless you do that though the machine will
wait for input even if netenv is configured. So take care if you want to
reboot the machine remotely. Please refer to the documentation for details.
You can:
1) Let me try to configure your actual network connection as the default
connection for netenv.
2) Configure one network connection now. Make sure you really save the
configuration. Otherwise you have to enter the configuration again during
the next boot.
3) Disable netenv usage at boot time.
