hostname don't asked when not set in ks.cfg

[Jerome Tournier]

Hello every body,
i set up a kickstart file to do everything automatically, exept the
hostname and network configuration. I whant those parameters to be asked at
the begining of the installation.
So nothing about that appear in ks.cfg.
The network configuration is automatically asked, but not the hostname one.
Anyone have an idea about how to force anaconda to ask me this ?
Thanks !
