I realise that this is older post but the question is related.
Thanks for the solution Jeff, it works but as soon as I reboot the omega2 it reverts back to its original hostname. Is there any way to make the hostname change permanent? I tried making a script on boot that will change the hostname, which works but I still cant use the new name to access the console via the browser or SSH into omega2 (the old name still works though).
Thanks in advance
