FWIW, we set our own "newhost" kernel parameter which we enable via  
"fai-chboot" (eg: fai-chboot -k newhost=mymachine ...).

The "newhost" kernel parameter is checked by our 
"/srv/fai/config/hooks/setup.DEFAULT.source" (attached).  As a fallback, 
if neither the HOSTNAME nor newhost variables are set, the hostname is 
set to be the ip-address of eth0, with dots converted to dashes.

So far, this reliably sets the hostname to the value of newhost in the 
newly installed target system.
