Disable per-host option in dhcpd.conf

[Sam Varshavchik]

Anyone knows how to disable an option in a host-specific entry in  
dhcpd.conf? I have:

subnet 192.168.0.0 netmask 255.255.255.0 {

  # …

   option routers 192.168.0.1;
}

host octopus {

  # I don't want this host to receive the routers option

}

Combing through dhcpd.conf(5), I don't see anything.

The octopus host is dual-homed on 192.168.2.0/24, with a router on  
192.168.2.1 that should be its default router.

I tried to override it with a host-specific "option routers 192.168.2.1"  
setting. This doesn't work, octopus routing is messed up:

default via 192.168.2.1 dev lan0  proto static  metric 1024
192.168.0.0/24 dev lan0  proto kernel  scope link  src 192.168.0.4
192.168.2.0/24 dev wan0  proto kernel  scope link  src 192.168.2.100
192.168.2.1 dev lan0  proto static  scope link  metric 1024

octopus's lan0 is the 192.168.0.0/24 segment. So this is wrong. octopus's  
wan0 port is on 192.168.2.0/24 is also BOOTPROTO=dhcp and I'd expect that  
network's router to control its routing, but looks like lan0's DHCP  
overrides it.

I suppose I can configure octopus's lan0 port for a static, non-DHCP boot,  
but I would like to keep it on DHCP, if possible.
