I spent hours changing the name via the DNS tab of system-config-network 
then changing the host file and rebooting only to find that the change 
would not hold.  The only way to have the change hold was to edit 
/etc/sysconfig/nework after a reboot and before the gui.  Any other 
method or combination of methods did not hold during subsequent reboots.
