Kickstart does not find client hostname when configuring networking

Issue

• using config file to set up /etc/hosts file during kickstart from Satellite

• config file uses macros to store client's hostname and IP address in /etc/hosts, e.g.:

  {| rhn.system.net_interface.ip_address(eth0) |}   {| rhn.system.hostname |} 
  

• hostname is not found, and is populated in /etc/hosts as "unknown"

• also, /etc/sysconfig/network has "localhost.localdomain" as the HOSTNAME
