HOSTNAME variable

[Hiro Protagonist]

sorry to bother again about this issue, but now i checked that my DNS 
server works correclty:
i can boot into the live system and "# dig" reverse DNS queries.

but "# hostname" still returns "fai-live-host" (which is also in 
/etc/hostname).

"# hostname -f" fails (temporary failure in name resolution). if i log 
in to the live system and change the hostname to the correct hosname by 
hand, "# hostname -f" also works.

the ${HOSTNAME} variable is always "fai-live-host".


again my question: where is the hostname (and the HOSTNAME variable) set 
during the FAI boot? how can i debug what's happening there? or is there 
another check i could run?

any ideas?

thanks in advance!
