Hi,

seeing the same (using dhcp for getting an ip address):

backes@eule [backes]: hostid
00000000

backes@eule [backes]: ifconfig
eth0      Link encap:Ethernet  HWaddr 00:0C:76:C0:40:36
          inet addr:192.168.179.182  Bcast:192.168.179.255 
Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:284 errors:0 dropped:0 overruns:0 frame:0
          TX packets:256 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:86392 (84.3 KiB)  TX bytes:25620 (25.0 KiB)
          Interrupt:22 Base address:0x2000

Not seeing this effect on systems without dhcp usage.
