deny option to specific hosts

Actually it is... 10.10.0.1 is an interface on the same router as
192.168.254.1... and DNS is listening on 0.0.0.0

Sometimes I need to take some of the options away from single devices (for
testing purposes) and I thought there would be any easy way to do this...
like "not option ntp-server;"

It actually works the other way around... If a dhcp client is not asking
for option XX you can make dhcpd to send it anyway, via "append
dhcp-parameter-request-list XX;"
