FAI not picking up hostname from DNS

[James]

> What's the exact symptom?
System won't pickup classes defined cause it can't define system 
hostname. I noticed it just default sets it to "host" and then choose 
the classes defined in the *) entry in the 50-host-classes file

my hostname is vm00.blahblahblah.com
here's my class entry:

 # use a list of classes for our demo machine
case $HOSTNAME in
    vm*)
        echo "FAIBASE DHCPC SETUPSTORAGE"   ;;
    *)
        echo "FAIBASE DHCPC SETUPSTORAGE"   ;;
esac

(ifclass I386 || ifclass AMD64) && echo GRUB
exit 0

I have no idea how i would set the hostname since i thought it would 
just know from DHCP + BIND

There's only one DHCP server running
