dhcpd.conf configuration

[mcrosby]

hello,
I am trying to configure my dhcpd.conf file to handle assigning multiple systems ip address' dynamically but i would like each system to mount a different root path. For example:
I want one system to connect with an ip of 192.168.0.1 and then mount /usr/local/boot1
and then if another system connects with an ip of 192.168.0.2 i would like it to mount /usr/local/boot2.
I also do not want to use any hardware ethernet recognition simply assigning dynamic ip addresses.
Below is simply a sample code of our actual config file:
subnet 192.168.0.0 subnet mask 255.255.255.0
{
range 192.168.0.1 192.168.0.100
option root-path "/usr/local/boot1";
}

Does anyone know how I would go about doing so?
