Hello,

I received a reply from the Jeffrey Hutzelman on the dhcp-hackers list who
basically told me not to create multiple classes, but instead put the subnet
specific options within the subnet portion of the shared-network statement.

It results in a rather longer configuration file, but it did the trick.

Thanks again,

Tor
