I'm a veteran dhcp user here trying to configure 4.1.0 for the first 
time from scratch on Fedora 11.  Unless I missed something, this 
config file should work:

option domain-name "pvt";
option domain-name-servers;
default-lease-time 600;
max-lease-time 7200;
ddns-update-style none;
#log-facility local7;

filename "vmlinuz";

subnet netmask {
	option subnet-mask;
	option broadcast-address;
	option routers;
	pool {

Here is eth0 interface configuration:

eth0      Link encap:Ethernet  HWaddr 00:1E:37:18:B2:6D  
          inet addr:  Bcast:  Mask:
          inet6 addr: fe80::21e:37ff:fe18:b26d/64 Scope:Link
          RX packets:2286226 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1353637 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100 
          RX bytes:2717713957 (2.5 GiB)  TX bytes:90141218 (85.9 MiB)

When I manually start the server I get the dreaded "No subnet 
declaration for eth0 (" message:

have been made to the base software release in order to make
it work better with this distribution.

Did I miss something, or is there a bug here?
